Subject: Review and Assessment of Newspaper Articles associated with the West
Berkeley Shellmound (CA-ALA-307) and the Spatial Relationship of this
Prehistoric Site to the Proposed 1900 Fourth Street Project
At your request, my associates and I have carefully reviewed the newspaper articles pertaining to
the West Berkeley Shellmound (formally designated as CA-ALA-307) as collected by Mr. Richard
Schwartz.
My associates and I have reviewed the articles and other materials provided by Mr. Schwartz, and
have also reviewed his comments on the Draft Environmental Impact Report (DEIR). The majority
of the accounts related to the excavation of the above-ground portion West Berkeley mound itself
and its immediate environs. These articles and notes, which ranged in time from the later 19th
century to well into the 20th century, recounted both amateur and academic explorations of the
mound. Those that provided location information placed the mound in its known location one
block west of the 1900 4th Street lot, or provided information that clearly tied the excavation to the
known mound.
A number of the articles on record recounted that the mound was being hauled away for road
bedding. As detailed in our testing report, the fact that the mound was moved during the historic
period is one factor that may create secondary shell midden deposits. Several of these early
newspaper accounts also mention attempts to preserve the mound.
Most informative were the articles recounting accidental discoveries of human remains and
associated artifacts in locations outside the block where the known portion of CA-ALA-307 once
stood. Though such finds reflect the neighborhood’s high sensitivity for prehistoric archaeological
remains, none of these accounts described locating any cultural materials within the 1900 4th Street
block. Such finds were concentrated primarily within and to the north and west of the CA-ALA-
307 block.
Allow me to turn my attention to the question about the 1884 article in the Berkeley Advocate that
describes burials being found at the Franklin House. The article refers to ten burials found at “the
2 5283 Broadway, Oakland, California 94618 ▪ (510) 601-6185 ▪ Fax (510) 601-8203 ▪ [email protected]
shell mound back [sic] of the Franklin House in West Berkeley” and notes that the remains were
turned over to university students (Anon 1884).
Schwartz, in his DEIR comments, states that “this find of ten human remains would have likely
been on the 1900 Fourth Street lot”. Our research shows that the Franklin House was located across
the tracks to the west of the 1900 4th Street lot, on the same block as the West Berkeley
Shellmound.
The Franklin House was a two-story hotel built along the railroad line in the late 1870s (Cohen
2008). It was illustrated in an 1885 promotional publication as a large, two-story structure with a
wraparound covered veranda (Elliott 1885). City directories dating to the late 19th and early 20th
centuries specified its location at the intersection of 3rd and University. The Franklin House
changed its name to the Ocean View Hotel in 1904 (Husted 1904:655).
Husted’s 1892-93 city directory clearly specifies that the Franklin House was located at the
northwest corner of 3rd and University, which is across the railroad tracks from the 1900 4th
Street block (Husted 1892:806). Maps dating to the era – specifically, the 1905 U.S. Coast Survey
map and the 1911 Sanborn map – accordingly show structures on the northwest, but not northeast,
corner of that intersection.
City directories list Cornelius Maloney as the Franklin House proprietor in 1887 (Husted 1887).
In the 1890s, John J. Higgins ran the hotel; he was succeeded in the first decade of the 20th century
by Joseph Doran, during which time the name changed from Franklin House to Ocean View Hotel
(Husted 1892:806; 1903:1009; 1904:655). Henry Moskowitz was the proprietor in 1910 (Husted
1910:1100), around the time that the Sanborn Map was drawn. The 1911 Sanborn Map clearly
labels the structure at the northwest corner of 3rd and University as the Ocean View Hotel (Sanborn
Map Company 1911:61).
At this point, my associates and I are satisfied that neither the Franklin House/Ocean View Hotel,
nor the “mound back of” it, was located within the 1900 Fourth Street block, and that the above-
described evidence will suffice to convince Mr. Schwartz and any other concerned parties. If
additional evidence is required, we would be happy to look further into the matter.
I have also reviewed the map created based on Mr. Schwartz’s information and believe that it plots
the identified locations as accurately as possible given the limited information provided in many
of the referenced sources.
I hope the remarks in this letter are of use to you and your associates.
Sincerely yours,

Attention: Ms. Lauren Seaver Vice President, Development
Subject: Holocene Geology and Land Filling History 1900 4th Street, Berkeley, California 94710 Geosphere Project No. 91-03190-D
Dear Ms. Seaver:
At your request, Geosphere Consultants, Inc. (Geosphere), is pleased to present this report which documents the history of land fill and development in the area of the proposed project site at University Avenue and 4th Street in Berkeley California, commonly known as the Spenger’s Restaurant parking lot. We previously performed a design level geotechnical engineering study for the project, as well as provided supplemental design-related consultations. The scope of our current work addresses the history of fill placement and general development of the project area, and consisted of research of historic maps which document the site improvements and cultural history of the site. Of particular interest is the interaction of filling of the site with documentation of adjacent shell mounds. The presence of shell mounds is noted on various geologic and topographic maps and this letter provides a summary of the historic documentation of these shell mounds.
Site Description
The proposed project is located west of 4th Street in Berkeley, and bound by 4th Street on the east, University Avenue on the south, Hearst Avenue on the north, and the Union Pacific Railroad (UPRR) tracks on the west, as shown on Figure 1 - Site Vicinity Map. The geographic coordinates of the proposed site improvements are approximately 37.868 degrees north latitude and 122.300 degrees west longitude. The proposed project site is about 96,260 square feet in area, and is mostly occupied by a paved parking lot. A small, single-story building, occupies the southwest corner of the property. The property measures approximately 238 feet by 405 feet, and is essentially level. Project site elevations range between approximately 9.0 at the northwest and southwest corners of the property, to about 11.1 near the northeast corner of the property, based on City of Berkeley (COB) Datum (El. 100.00 COB Datum = El. 103.17 NGVD 1929 or Mean Sea Level Datum). The local topography slopes west toward San Francisco Bay. Site drainage is controlled by nearby Strawberry Creek which has been placed into a culvert and re-routed away from the site. Historically, Strawberry Creek passed through the majority of the site, and the creek has subsequently been re-routed into a culvert located below adjacent University Avenue (Sowers and Richard, 2009).
Site Geology
Geologic maps indicate native materials underlying the site and Strawberry Creek alluvial and marsh deposits to consist of Quaternary-age alluvial fan deposits of the Temescal Formation. A generalized geologic map of the site vicinity is presented as Figure 2 - Site Vicinity Geologic Map. Holocene geologic mapping (Radbruch, 1957) shows
Geosphere Project No. 91-03190-D January 31, 2017

deeper soft Bay Mud deposits located adjacent to the southwest corner of the proposed site within the old tidal inlet, and creek flood plain deposits extending across the site in a southwest to northeast direction, crossing to the east side of 4th Street. Our previous site investigation encountered fill within the upper four to five feet of the site with deep estuary/marsh deposits below. The majority of the site is underlain by young marsh deposits, with no marsh deposits present at the far north end of the site. A cross-section of the Holocene geology is presented in the attached Figure 3 – Cross Section A-A’.
Land Filling History
We performed a review of historic maps available through sources including the following:
U.S. Geological Survey County of Alameda University of California, Berkeley
California Geological Survey City of Berkeley U.S. Coast and Geodetic Survey
Based on this research, we developed a history of fill placement within the project location. Attached with this report are copies of the maps discussed in the following sections.
1856 U.S. Coast and Geodetic Survey (Figure 4)
This map is the earliest map that we could readily find of the site. This map showed some of the preliminary land subdivision lines which were remnant of the original California Rancho subdivision of the land, as well as the original alignment of San Pablo Road (present San Pablo Avenue). We used these landmarks to overlay the existing site location on the map. At the time of this map, there were almost no identified structures and there was no filling of the bay marshlands. This map reflected an unaltered shoreline and estuary area. To the west and east of the project site were two topographic mounds as shown on this map. These mounds are not depicted on the project site. These two mounds were later interpreted to be shell mounds (Nels Nelson, 1909). The topographic map showed that the majority of the site was occupied by the Strawberry Creek estuary and the site was flat with no topographic rise on it.
1884 Dingee Real Estate Map with Shell Mound (Figure 5)
Between this time and the 1856 map, significant subdivision and development of the West Berkeley area had taken place. The site is located adjacent to the Central Pacific Railroad alignment and was designated as Lot 88. The adjacent parcel to the west, across the railroad alignment, was designated as Lot 89. Lot 89 appeared to have a topographic hill depicted on it which we interpret to be a remnant of the shell mound identified in the 1856 U.S. Coast and Geodetic Survey map. We note that Lot 87 to the east and 74 to the northeast showed no similar topographic hill depiction and we can only surmise that the eastern mound may have been removed for development purposes. At this time, the original bay margin to the west appeared to be unaltered by bay filling.
1909 Nels Nelson Shell Heaps Map (Figure 6)
This map is part of a work performed by UC Berkeley Professor Nels Nelson to document the shell mounds of the San Francisco Bay. The map is a key map identifying locations in a general location and does not have site specific locations and boundaries. It provides a general designation that there were shell mounds near the mouth of Strawberry Creek but does not provide the site specific detail in the 1856 or 1884 Dingee maps.
1915 USGS Topo Map (Figure 7)
At this time, the area was developing. The topographic map shows Strawberry Creek crossing through the southern side of the site. Buildings were located on the southeast and central east side of the site. There were
Geosphere Project No. 91-03190-D January 31, 2017

structures shown on the parcels to the east and west, but Strawberry Creek was still shown as a surface-flowing creek. Based on the more constrained alignment of the creek, it appears that some filling of the north-central portion of the site may have occurred by this time. Some filling of the bay is observed along the north side of the Berkeley Pier.
1942 USGS Topo Map (Figure 8)
By 1942, it appeared that Strawberry Creek had been placed into a culvert several blocks to the east. A small building still occupied the southeast corner and a much larger structure occupied the northeast 1/3 of the site. Filling of the bay lands was taking place to the northwest of the area near present day Golden Gate Fields, but lands adjacent to the Berkeley Pier appeared to be similar to the 1915 map. Filling had taken place for the construction of U.S. Highway 40, which would later become Interstate 80.
1946 USGS Topo Map (Figure 9)
By this time, the filling and adjustments to the subject site appeared to be consistent with today. The large structure in the northeast side of the site was still shown on the topographic map. Future filling will occur at the Berkeley Marina to the west, but the subject site had no further evidence of change, except for the removal of the buildings shown on the site.
1957 USGS Geology and Topo Map (Figure 10)
The 1957 Radbruch map was prepared as an engineering geology/ geologic map which included a summary of previous data from the 1856 U.S. Coast and Geodetic Survey map as well as provided mapping of the extent of estuary deposits related to Strawberry Creek. This map superimposed select 1856 mapping of water-related features (e.g., shell mound locations, tidal flats, old shorelines, and historic location of creeks, including the Strawberry Creek channel) on a map showing 1957 topographic contours and physical features (e.g., streets and significant buildings), as well as geologic mapping of soil and bedrock formations. On this map, the shell mounds are clearly mapped to the west and east of the site, with no shell mounds present on the project site itself. In addition, the map shows the project site to clearly be occupied by the filled tidal flat and marsh area associated with the mouth of Strawberry Creek.
Figure 11 is a composite figure with data compiled from the 1856 shoreline map, 1884 subdivision map, and 1957 geologic map and showing the location of the project site. This figure shows that all of the mapped shell mounds are in close proximity to, but not encroaching upon the project site. Figure 12, which shows the mapped shell mounds superimposed on the 1957 topographic map showing present day street locations, is similar to Figure 11, showing that the mapped shell mounds do not encroach onto the project site.
Conclusions
We have traced the site development through a review of published maps readily available through public records as well as our borings. The subject site started to be developed between 1856 and 1884. This most likely occurred as the Central Pacific Railroad was constructed to provide access in the 1870s. Mapping from 1856 showed the vast majority of the site to have been occupied by the Strawberry Creek tidal marsh. This mapping is consistent with the information generated from our exploratory test borings, and our findings during our site investigation. The cross-section of soils readily shows that most of the site is underlain by the marsh deposits. Our research shows that topographic mounds interpreted to be shell mounds were located on the lot to the west and the lot to the east, but not on the subject project site itself. The historic maps indicate that the Strawberry Creek channel area occupied the project site until sometime between 1915 and 1942, when the project site was filled, and the

Subject: Review and Assessment of the Boundaries of the Prehistoric Archaeological
Site Commonly Known as the West Berkeley Shellmound (CA-ALA-307) and
the Spatial Relationship of this Prehistoric Site to the Proposed 1900 Fourth
Street Project
Dear Ms. Seaver:
At your request, my associates and I have carefully reviewed the substantial body of literature
(consisting of both scientific studies and anecdotal sources) pertaining to the West Berkeley
Shellmound (formally designated as CA-ALA-307) in an attempt to determine the most likely
location, boundaries and dimensions of this prehistoric archaeological site before it was
subjected to massive and repeated episodes of topographic modification and degradation,
beginning nearly 150 years ago and continuing well into the second half of the 20th century.
Specifically, my associates and I have evaluated the available historical sources to determine
whether the historical boundaries of CA-ALA-307 correspond to that portion of West Berkeley
that has been designated, or “Landmarked,” by the State of California and the City of Berkeley
as representing the horizontal extent of the West Berkeley Shellmound. Finally, as I have done
on numerous past occasions, I shall comment upon the body of evidence concerning the spatial
relationship between the location and boundaries of CA-ALA-307 and the proposed 1900 Fourth
Street Project – i.e., the block of West Berkeley bounded by University Avenue on the south,
Hearst Avenue on the north, Fourth Street on the east and the Union Pacific Railroad tracks on
the west.
Allow me to come directly to the point. While there can be no question that the area that has
been designated for Landmark status by both the State of California and the City of Berkeley as
representing the horizontal borders of CA-ALA-307 exists within a zone of prehistoric
archaeological sensitivity, it is much less clear whether significant portions of the West Berkeley
Shellmound ever actually covered portions of this designated area, including much, if not all, of
the proposed 1900 Fourth Street Project block. Indeed, a review of the available historical
evidence suggests that this prehistoric shellmound was situated largely, perhaps entirely, to the
west of the Union Pacific Railroad tracks and, hence, beyond the borders of the 1900 Fourth
Street Project area.
2 5283 Broadway, Oakland, California 94618 ▪ (510) 601-6185 ▪ Fax (510) 601-8203 ▪ [email protected]
The primary lines of inquiry that led to this conclusion are these:
1. Although the exact boundaries of the “original” West Berkeley Shellmound were unclear even in the early 1900s, early archaeological studies generally agreed that the majority or
entirety of the shellmound were situated to the west of the railroad tracks prior to
historical disturbance.
2. Historical sources, including the 1856 Coast Survey manuscript map and archaeological notes from 1900-1911 (U.S. Coast Survey 1856; Nelson and Peterson 1911), indicate that
a second smaller shellmound was present to the east of what we now call the West
Berkeley Shellmound; the second mound was recorded roughly where the Anthropologie
store is now, and is probably the origin of human remains found recently east of Fourth
Street.
3. Subsurface investigations that my associates and I carried out in 1999, 2000, and 2014 identified lenses of shell in what is, in my estimation, a disturbed context underneath the
1900 Fourth Street property; we found no evidence of an in situ extension of the
shellmound or human remains.
4. A geoarchaeological study by Garcia and Associates in the early 2000s identified a distinctive paleosol in the vicinity of the West Berkeley Shellmound, which they believed
to correspond with the soil layer recorded immediately underneath the shellmound. This
paleosol was carved away and repeatedly flooded by the many branches of Strawberry
Creek while the site was occupied; instances of shell observed in Archeo-Tec’s repeated
investigations of the 1900 Fourth Street property have all been found within the alluvial
creek deposits rather than on the paleosol, and so were most likely displaced from their
original locations.
Before proceeding further, it is not my intention here to once again reiterate the findings of
previous archaeological studies concerning the areal extent of the West Berkeley Shellmound.
These studies have been adequately discussed and assessed in a variety of reports and other
documents, including Archeo-Tec’s 2014 detailed report entitled “A Report on the
Archaeological Testing Conducted within the Spenger’s Parking Lot, Bounded by University
Avenue, Hearst Avenue, Fourth Street and the Tracks of the Union Pacific Railroad, City of
Berkeley, Alameda County, California” (Archeo-Tec 2014). Rather, my intention in this letter is
to provide a synopsis of what is known and what remains undetermined about the location,
boundaries and dimensions of the West Berkeley Shellmound.
At this point, it is important to note that the exact location, dimensions and boundaries of the
West Berkeley Shellmound (CA-ALA-307) were never delineated with any degree of precision.
This lack of crucial information can be attributed to a variety of factors. For one, by the time
archaeologists arrived on the scene to assess the West Berkeley Shellmound during the first
decade of the 20th century, the site had already been subject to massive disturbance (Furlong et
al. 2006). Substantial portions of the mound had already been leveled, and the disturbed deposit
had been spread over a relatively widespread area of West Berkeley. There are numerous
accounts of site looting and the unauthorized collection of artifacts and human remains at the
West Berkeley Shellmound between the later years of the 19th century and at least the mid-20th
century. As such, even more than a century ago, the task of determining the specific location and
dimensions of the mound in its “original” state is extremely difficult.

In addition, one has to be careful about what is meant when one speaks of the mound in its
“original” condition. There is no doubt that the West Berkeley Shellmound is one of the oldest
prehistoric archaeological sites in the San Francisco Bay region. There is general agreement
within the local archaeological community that CA-ALA-307 was first inhabited some 3,500
years ago, possibly even earlier than that. There can be little doubt that the location, dimensions,
constituents, and number of inhabitants of the site changed substantially over this long span of
time. Hence, if we are talking about the size and condition of the mound at the beginning of the
historic era, toward the close of the 18th century, that is not necessarily the same as assessing the
size and condition of the site 500, or 1,000, or 1,5000 years earlier. The changing conditions of
the site over time, and the reflections of these changes in the archaeological record, must be
borne in mind even though they are very difficult to assess with any degree of specificity.
With these interpretive obstacles in mind, let me summarize what is known, or generally
believed, about the location and dimensions of the West Berkeley Shellmound. Most of the early
scientific studies, including the pioneering early 20th century work of N.C. Nelson and the mid-
20th century investigations of Wallace and Lathrap, concur that the specific location, size and
dimensions of CA-ALA-307 were never properly or precisely delineated (Furlong et al. 2006;
Wallace and Lathrap 1975). For the most part, these studies seem to offer general agreement that
the most substantial portion, if not the entirety, of CA-ALA-307 was, in its “original” state,
situated to the west of the Union Pacific Railroad tracks, and hence, to the west of the western
border of the 1900 Fourth Street Project site. Indeed, recent construction work monitored by
archaeological observers has confirmed that a substantial prehistoric deposit, presumably a
remnant of the West Berkeley Shellmound, exists below the surface of the ground to the west of
the Union Pacific Railroad tracks.
It should be noted, however, that N.C. Nelson’s 1910-1911 notes, which he indicates are a
revision of Peterson’s 1904 work, make reference to a second shellmound, located in relatively
close proximity to the east of CA-ALA-307 (Nelson and Peterson 1911). It is possible that
Nelson’s observation may be reflected in the recent discovery of prehistoric archaeological
materials, including human remains, within the 1919 Fourth Street Project site, situated directly
to the east of the 1900 Fourth Street Project site. It should be stressed that the spatial, functional,
temporal and/or historical relationships, if any, between the West Berkeley Shellmound and the
recently-discovered prehistoric cultural deposit at 1919 Fourth Street remain undetermined at the
present time.
In 1999, 2000, and 2014, my associates and I undertook systematic subsurface archaeological
investigations within the borders of the 1900 Fourth Street Project site. In 1999 and 2000, my
associates and I excavated and evaluated a total of 43 mechanical exploratory borings within the
borders of the Spenger’s Parking Lot (Pastron 2000). In 2014, my associates and I excavated
and evaluated a series of mechanical exploratory trenches and one large areal exposure at
selected places within the project area (Archeo-Tec 2014). As indicated in Archeo-Tec’s 2014
report, a number of thin, scattered lenses of shell, possibly derived from the nearby CA-ALA-
307, were identified in various locations beneath the surface of the ground within the 1900
Fourth Street site. However, nothing that was found was deemed to represent a primary (in situ)
prehistoric archaeological deposit. Indeed, the archaeological investigations failed to identify
any “historically significant” prehistoric cultural resources or, most importantly, human remains.

Finally, allow me to address the question from a geoarchaeological perspective. Shellmounds,
and the geographic history of their associated landscapes, are extremely complex features. The
West Berkeley Shellmound was formed by changing populations, in a dynamic landscape, over
millennia. Geographic changes (e.g., sea level changes, shifting locations and depths of
Strawberry Creek, seasonal flooding, erosion of the bay shore by wave action) took place before,
during, and after the mound was deposited. Geoarchaeology takes this geomorphology into
account in assessing site formation and natural post-depositional processes, all of which took
place before 19th- and 20th-century removal of the mound resulted in human-caused re-
deposition, and before these layers were subsequently buried by landfill.
In 2001, Garcia and Associates, under Principal Investigator Christopher Dore, performed a
geoarchaeological assessment of the neighborhood surrounding both the 1900 4th Street block
and the known location of CA-ALA-307 (Dore et al. 2002). A hundred and twenty-four cores
were placed, and detailed information regarding the area’s geomorphology, as well as cultural
deposits, was collected. Thirty-three of these samples revealed cultural deposits, and of these,
sixteen were interpreted as primary deposits.
Dore’s study was able to identify a paleosol—an ancient soil layer clearly pre-dating human
occupation—at numerous locations within his study area. This layer, consisting of a flat alluvial
deposit topped with clay, sits atop bay mud and was deposited before all known human activity;
it thus forms a sort of basement for cultural deposits. According to Dore’s assessment of Wallace
and Lathrap’s mid-20th century archaeological excavation, CA-ALA-307 appears to sit directly
atop this intact layer, suggesting that it represents a prehistoric habitation surface. During periods
of low sea level, the many shifting channels of Strawberry Creek carved through this paleosol
level all the way down to the underlying bay mud.
In a 2004 paper detailing the geoarchaeological investigations in West Berkeley, Dore et al.
suggest that midden deposits identified in Archeo-Tec’s 1999-2000 study, which was ambiguous
at the time due to the limited context available from a boring, were in a primary rather than
secondary context (Dore et al. 2004:30). However, this question has been made clearer by our
larger 2014 exposures at 1900 Fourth Street, which targeted the areas in which deposits had been
identified in the earlier borings. Small pockets of shell midden were found during our testing
program amid deep alluvial gravels from ancient channels of Strawberry Creek directly
overlying bay mud, rather than, as at the West Berkeley Shellmound, atop the intact paleosol.
As our testing report points out (Archeo-Tec 2014:36), the trace midden deposits that were found
during our testing program appear to be materials from the nearby shellmounds that were
redeposited, either by the creek (in the case of deeper deposits found in natural alluvial layers) or
by historic period disturbance to the shellmound (in the case of deposits found alongside
historical trash deposits). It remains my opinion that the prehistoric materials we have identified
within the 1900 Fourth Street property are depositionally distinct from CA-ALA-307 and does
not likely represent an extension of the mound itself.
In summary, based on the information my associates and I have reviewed and assessed, there is
no evidence that demonstrates that any portion of the primary deposit associated with CA-ALA-
307 exists within the borders of the proposed 1900 Fourth Street Project. This is not to
conclusively state that such cultural remains may not exist somewhere within the block bounded
by University Avenue, Hearst Avenue, Fourth Street, and the Union Pacific Railroad tracks.

What I can state is that such evidence was not encountered at any time during the course of the
three discrete programs of subsurface archaeological investigation conducted under my
supervision by personnel of Archeo-Tec within the above-described project site between 1999
and 2014. Similarly, my review of prior archaeological investigations and anecdotal reports did
not provide any evidence either. Given these findings, it is my conclusions that the area that has
been “Landmarked” by the City of Berkeley and the State of California may, in fact, not
correspond directly with the location and dimensions of CA-ALA-307. Based on the evidence I
have reviewed, the evidence suggest that the West Berkeley Shellmound was located primarily,
if not entirely, to the west of the Union Pacific Railroad tracks and that the outer boundaries of
the West Berkeley Shellmound remain somewhat ambiguous. Although the exact boundaries
remain ambiguous, none of the deposits found during my extensive subsurface archaeological
investigations included primary (in situ) prehistoric archaeological deposit, so at this time there
is no evidence that the West Berkeley Shellmound exists within the borders of the proposed 1900
Fourth Street Project.
I hope the remarks in this letter are of use to you and your associates.
