Table of Contents The California desert is a land of stark contrasts: Extreme heat and bitter cold. A geology hewn by volcanic fire and Ice Age lakes. Sahara-like dunes shimmer in the sere heat, and lush green oases beckon with year-round water.
Guarding this primeval beauty are pastel-hued mountain ranges and vast valleys spanning almost endlessly across the horizon.
It is a place that stirs our imagination and pioneer spirit.
This is the American West, and its timeless desert treasures are rich in culture and heritage. It’s where visitors can see traces of prehistoric peoples, Spanish and stagecoach trails, and the origins of the first U.S. highways.
Life also thrives here, even in the harshest of conditions.
In the Amargosa River – where air temperatures can soar past 115, or dip to near freezing – a tiny pupfish can live in salty waters, a holdout from a wetter climate thousands of years ago.
The desert is also home to bighorn sheep, desert tortoise, hundreds of birds, reptiles and many other animals, all well-adapted to heat and low precipitation.
Forests fill these wild lands, but their Joshua trees, spiny cholla and yucca are more akin to whimsical Dr. Seuss characters than stately pines. And after winter rains or summer thunderstorms, this arid landscape magically transforms into a fleeting panorama of vibrant wildflowers and blooming shrubs.
The unique legacy of the California desert attracts residents and visitors with its spectacular scenery, recreation opportunities and diverse history. These delicate wild lands can continue to be places of discovery if they are preserved.
California’s desert treasures should be protected from renewable energy and other development. Safeguarding the desert will ensure it will be enjoyed by today’s families and generations to come.

Ice age lakes fed a mighty Owens River
that rushed over black basalt from volcanic
eruptions as recent as 20,000 years ago. As
fiery lava poured into the river, the rushing
water sculpted and polished the rock into
waterfall-like formations.
Visitors to Fossil Falls can explore this
volcanic landscape by peering over the
steep drops of the now-dry falls. Also, to
the north, a red cinder cone looms. The cone
was formed when underground magma and
gas exploded into the air from a vent on the
Earth’s surface.
Fossil Falls is also rich in prehistoric
and Native American cultures.
Boulders bear well-worn metate marks
where seeds were ground into food.
Rock rings are the remnants of former
tule grass shelters. And some rocks are
carved with ancient petroglyphs etched
by native peoples.
Early inhabitants also crafted volcanic rock
such as obsidian into tools and spear points.
Today, evidence of this skilled tool making
can still be found in the many stone chips
and flakes that litter the ground.
Archaeological sites at Fossil Falls are dated
between 4000 BC and the 19th century.
Indians had thrived here for millennia,
up until the Little Lake Shoshone were
met by the first European explorers.
Fossil Falls is a short drive off of
Highway 395 and there is a rest area,
picnic tables and restrooms. An easy
trail leads to the falls and there’s a
rustic campground.

Stop off the highway, and seconds of
absolute silence seem to slow to minutes.
The horizon is unobscured, and a column of
thunderclouds can easily be 10 miles away,
or perhaps 100 – one’s vision tricked by
the land’s emptiness. Sunrises extend their
first rays onto the magnificent Argus Range
on the west, across Panamint Valley, to the
towering Panamint Range in Death Valley
National Park to the east.
Sitting 1,000 feet above sea level, and
spanning 65 miles from north to south,
Panamint Valley offers a glimpse of its
historic mining legacy, rains that spawn
seasonal wetlands and wildflower fields
and side trips to unusual sights.
In the southeastern end of the valley,
a four-wheel drive and hike up Surprise
Canyon will delight visitors with a year-
round cold and clear stream tumbling out
of the mountainside – an oasis for humans
and wildlife including desert bighorn sheep.
Mining and history buffs can also ponder the
facts, or fiction, of the ghost town Ballarat
that lies near the base of Surprise Canyon.
Much of the valley can be enjoyed by
simply driving. To explore the northern
areas, Highway 190 to Death Valley
offers spectacular views. And when road
conditions allow, take the Trona-Wildrose
Road, a scenic, two-wheel drive route
linking Panamint Valley to the unusual
formations of Trona Pinnacles in
Searles Valley to the south.

2Fire and ice conspired to create
dramatic Fossil Falls, a geologic wonder
at the southern tip of the Owens Valley.
Panamint Valley’s stunning beauty reveals itself in
the vastness of its wild vistas. A time-traveler’s dream,
the valley downshifts visitors to nature’s rhythm.

History
Amargosa River
Located near the southeastern entrance to
Death Valley National Park, the Amargosa
River is a rare perennial waterway in the
Mojave Desert. Dubbed the hide-and-seek
river because much of it is underground,
it surfaces and winds through Amargosa
Canyon, nurturing lush “hanging gardens,”
marshes and mud flats.
The Amargosa’s waters sustain a rich tule
marsh habitat attracting bobcat, badger,
the endangered Amargosa vole, the
Amargosa pupfish and more than
200 bird species including Phainopepla
and Summer tanager.
Humans have also been drawn here.
What are believed to be prehistoric paths
later evolved into overland routes including
the Old Spanish Trail used by 1820s
traders in the former Spanish territory.
Early American explorers and Mormons
later favored this route.
Today’s travelers can enjoy scenic vistas
off Highway 178 or the Old Spanish Trail
Highway, east toward Pahrump, Nevada.
Well-equipped, four-wheel drive vehicles
can retrace the old Tonopah and
Tidewater railroad bed.
Hikers can access scenic Amargosa Canyon
trails starting at the China Ranch Date Farm.
One path meanders along the river, another
reaches a narrow slot canyon with steep
walls. And an easy one-mile walk connects
to the Grimshaw Lake wildlife site.
Former mining towns also have visitor
activities. Tecopa has hot springs,
and there’s a local and natural history
museum in Shoshone.

In fact, water played a key role in forming
the unique, often eerie, spires at Trona
Pinnacles. Between 10,000 to 100,000
years ago, this part of the Mojave desert
was underwater and part of the alkaline
Searles Lake. Over time, calcium carbonate,
in a form known as tufa, formed
underwater pinnacles.
As the Ice Age receded, Searles Lake,
one in a chain of Pleistocene lakes along
California’s northeast spine, went dry,
exposing several hundred tufa towers.
Today, this alien landscape is popular for
hiking, primitive camping and movie and TV
shoots (including sci-fi productions “Lost In
Space” and “Battlestar Galactica”).
In 1968, Trona Pinnacles was designated a
National Natural Landmark by the Bureau of
Land Management to protect these rare tufa
formations and their curious shapes:
• Towers: Taller than they are wide, these
are 30 to 40 feet high, with pointed,
rounded, or flat tops.
• Tombstones: Dense and squat,
like a headstone, these can rise to
20 to 30 feet.
• Ridges: These are massive and toothy
tufa expanses. The largest at Trona
Pinnacles is 800 feet long,
500 feet wide and 140 feet tall.
• Cones: Less than 10 feet tall, cones
can be pointy or mounded.
To explore Trona Pinnacles, there’s a
half-mile hiking trail, dirt driving routes
and primitive camping. Its solitary beauty
is best experienced at sunrise, sunset,
or lit by a full moon.

Trona Pinnacles
3 4When desert winds whisper through Trona Pinnacles,
they resemble the lull of ocean waves heard
through a conch shell.
With its rare year-round desert river, the Amargosa River
region has enticed ancient peoples, wildlife and explorers
for thousands of years.

Subtle, multicolored layers of sandstone,
tuff and siltstone are striated in pink,
sienna, green and cream, their hue
and intensity changing from early
morning to dusk.
The rock walls and craggy formations
also bear evidence of erosion as well
as earthquake faults that have bent
and folded the earth’s crust like
saltwater taffy.
Hidden within these layers, and exposed
over time from erosion, researchers have
identified a significant trove of mammal
fossils dating back 15 million years.
Fossil plants hint at an ancient landscape
far different from today: tree-filled hills
by a lake, populated by giant bear dogs,
rhinoceros, early camels and horses. Today,
only researchers with a special permit
can collect fossils, to protect this rare and
important site.
Much of Rainbow Basin’s scenic beauty can
be enjoyed by driving the marked roads,
while walkers can get a closer view on
established hiking trails. Photographers
also are drawn to this unusual landscape
that reveals its character across all seasons.
Four-wheel-drive vehicles can explore
the Fossil Canyon Loop road.
Wildlife thrives here and the best
opportunities to observe animals are
during early morning and evening hours.
Birdwatchers favor Fossil, Coon, and
Owl Canyons. Primitive camping is
available at Owl Canyon Campground.
Today, this vast valley, ringed by desert
mountain ranges, echoes with the vibrant
history of the Old West.
Archaeologists have found traces of
the Old Spanish Trail – the bustling,
1,200-mile historic trade route that linked
New Mexico to Los Angeles until the late
1800s. Recently, remnants of a ceramic
smoking pipe, its bowl shaped with the
head of President Zachary Taylor, and other
relics were discovered in Silurian Valley.
It’s also a place where winter rains foster
spring wildflower blooms and temporary
lakes draw migratory birds.
But the enduring beauty of Silurian Valley
is in the sheer size of the landscape:
a cyclorama vista of expansive valley
guarded by the majestic Avawatz Mountains,
Soda Mountains and Kingston Range and
crowned by endless sky.
The valley also lies between two of
California’s most scenic natural landmarks,
the Mojave National Preserve and Death
Valley National Park, connecting the parks
with nearby wilderness areas.
Standing within Silurian Valley today,
one can imagine what it was like to be
an early explorer heading west to the
“promised land” of California.

5 6Nature’s soft pastel palette and its artful sculpting of
desert geology lie within the hills, canyons and washes of
the Rainbow Basin Natural Area just north of Barstow.
The remote and beautiful Silurian Valley is named for an
ancient geologic period, when plants and animals began
to emerge from the sea onto land.
Rainbow BasinSilurian Valley
The river’s canyon, nestled between the
San Jacinto and San Bernardino Mountains,
sustains a rich habitat for bighorn sheep,
bears and endangered species including
Southwestern willow flycatcher and the
Coachella Valley fringe-toed lizard.
Winter views are framed by white-capped
rapids and dramatic snow-capped peaks,
while hot summers can dry the river to a
trickle, leaving only underground flows.
One of the best places to explore the area
is at the 2,851-acre Whitewater Preserve,
nearly hidden in a canyon just north of
Interstate 10 near Palm Springs.
Preserve trails offer wilderness mountain
views and some sections intersect the
Pacific Crest National Scenic Trail. Historic
trout ponds, a visitor center and camping
are managed by The Wildlands Conservancy.
In the cooler spring, families can enjoy
bird watching, star gazing and childrens’
catch-and-release fishing.
Most of the Whitewater River’s
headwaters start high atop 11,503-foot
Mt. San Gorgonio, Southern California’s
tallest peak, rushing down through alpine
forests to the desert floor far below.
In the 1800s, Spanish explorers dubbed the
river “agua blanca” or “white water” for its
turbulent rapids. In 1850, the Whitewater
Ranch was established, later serving as a
stagecoach stopover.
Today, the former cattle ranch is the
preserve, and downstream the Whitewater
River eventually disappears underground,
percolating through the arid desert floor,
replenishing a critical aquifer for the
Coachella Valley.

By the 1920s – and the birth of U.S.
Highway 66 – streams of automobiles
were traveling across the Southwest and
the California desert.
Today, the longest remaining undeveloped
stretch of ‘the Mother Road’ in eastern
San Bernardino County offers spectacular
and serene desert vistas of Old California.
Route 66’s unique scenery includes the
Cady Mountains that tower 3,980 feet above
Sleeping Beauty Valley—one of the few
intact Mojave valleys with hundreds of plant
species, some of them rare. This area is also
an essential corridor for desert tortoise and
desert bighorn sheep.
Just beyond these wildflower-dappled lands
are several prominent features including:
dramatic Amboy Crater, a National Natural
Landmark; the Pisgah lava flow; the Clipper
Mountains and expansive Fenner Valley.
These former railroad lands are now publicly
owned by the Bureau of Land Management
(BLM), and towns along Route 66 are
working with the BLM to preserve its unique
heritage and beauty.
Important historic landmarks include ghost
towns and the Harvey House rail depot
in Barstow. Route 66, also known as the
National Trails Highway, was named by
Smithsonian Magazine as one of
10 Must-See Endangered Cultural Treasures.
10
7 8Beneath the aging pavement of historic Route 66 lie the dusty trails
once traveled by hardy pioneers who settled the Old West. Later,
railroads followed these trails and further opened frontier lands.
Its waters nourishing parched lands, the year-round
Whitewater River has enticed explorers, wildlife and visitors
drawn to this rare desert creek for centuries.

Located northeast of the Salton Sea, an
aerial view of the bench reveals a bajada
–an alluvial fan or triangular sweep of land
striated by washes, nestled between the
Chuckwalla Mountains and the
Chocolate Mountains.
During seasonal storms, the bajada’s
‘irrigation’ system sustains a thriving
desert forest of yellow-flowering palo verde,
ironwood trees dappled in lilac blooms,
scarlet ocotillo, desert willow with its showy
pink flowers, mesquite, Joshua trees and
the rare Munz cholla.
This diverse habitat attracts a rainbow of
bird species including hawks, warblers,
tanagers and hummingbirds. The rarely
seen burro deer, a thriving population
of endangered desert tortoise and the
namesake chuckwalla also live here.
History buffs are drawn to the Bradshaw
Trail, once part of a 70-mile-long
stagecoach route from the 1860s named
for miner William David Bradshaw. The route
was quickly dubbed the “Gold Road” for the
many miners traveling to the Arizona gold
fields from San Bernardino in search of their
glittering fortunes.
Today, it is a popular four-wheel-drive road
with sweeping mountain and valley vistas,
bighorn sheep sightings, and primitive
desert camping for well-equipped visitors.
Named for the Morongo Indians who thrived
here before the arrival of white settlers,
it is the only spot in the desert where
Big Morongo Creek surfaces and feeds a
verdant marsh and oasis. The creek bubbles
for three miles along a fault in the canyon
before it disappears underground.
Today this 31,000-acre nature preserve is
shaded by a dense canopy of cottonwoods
and willows that make it among the
10 largest river habitats of its type
in California.
Located off Highway 62, southeast of
Morongo Valley (and 15 miles north
of Palm Springs), the preserve is an
internationally recognized bird-watching
destination that draws wildlife seekers
who can view a remarkable diversity of
birds, plants and animals.
The Audubon Society identifies Big Morongo
Canyon as one of California’s most important
bird habitat areas and the American Bird
Conservancy considers it one of the United
States’ Important Bird Areas. Hundreds of
species are seen here including Vermillion
flycatcher, Yellow-breasted chat, Golden
eagle and endangered Least Bell’s vireo.
Bobcats, desert bighorn sheep, mule deer,
Pacific tree frogs and other animals are
also common.
Big Morongo Canyon is a unique transition
zone and wildlife corridor connecting the
higher Mojave Desert and Joshua Tree
National Park to the lower Colorado Desert.
The canyon is open daily and features trails,
a wheelchair-accessible boardwalk, picnic
facilities, restrooms and trail displays.

Chuckwalla BenchBig Morongo Canyon
9 10Like a hidden desert jewel, Chuckwalla Bench is rich with stagecoach
history, a flourishing desert woodland and a cornucopia of wildlife
including endangered desert tortoise and more than 150 bird species.
For centuries, the desert oasis in Big Morongo Canyon
enticed both Native Americans and animals drawn to
its life-sustaining creek.
14
The valley is laced with an intricate array
of alluvial washes, or bajadas, flourishing
with ironwood and palo verde trees. At
the northwest end of the valley, up toward
Palen Pass, is one of the largest and lushest
ironwood forests in the California desert.
Some individual trees are so impressive
scientists have named them the
“Palen Pass Huge Ironwood Trees.”
Indians once made tools and weapons
extensively from ironwood because of the
wood’s durability; it is so dense, it sinks in
water. Ironwood seeds were also a key
food source for tribes.
Natural rock depressions along the
flanks of the nearby mountains known as
tanks fill with seasonal rainwater. These
life-giving water sources drew Indians,
explorers and wildlife over the centuries.
Evidence of ancient people can be found in
petroglyphs, cleared circles, used pottery
and groundstones.
Wildlife thrives in the wooded bajadas
including burro deer, coyote, bobcat, gray
fox and mountain lion. Desert tortoise
frequently make their home here.
And bighorn sheep roam the mountains and
the bajadas and drink at the tanks.
This area, from the deep slanted canyons
and jagged peaks of Indian Pass Wilderness
to the old mesquites, palo verde trees, and
ironwoods in Milpitas Wash, hosts a diverse
variety of wildlife. The washes and rocky
slopes are home to desert tortoise and
mule deer. Signs of mountain lion and
bighorn sheep are also evident in nearby
crags and canyons.
For thousands of years, these lands have
been an important part of the traditional
homeland of the Quechan tribe who were
formerly known as Yuma Indians. Ancient
trails, intaglios (large ground etchings),
rock alignments, sleeping circles, remnants
of stone tools and other evidence of
the tribe’s long history are still found
throughout the area. Many cultural sites are
nearly invisible to the untrained eye but are
still used today by tribal members.
A forest, lush by desert standards, thrives
in the lowlands of the Milpitas Wash region.
Some trees stand almost 15 feet high, and
showy desert willow grows in the washes.
The Quechan buried their relatives on
these lands, and spiritual journeys
through the trails and canyons hold special
significance to the tribe. It is still possible
to detect ancient trails walked by their
people for generations.

Upper McCoy Valley Indian Pass to Milpitas Wash
11 12Upper McCoy Valley is nestled between the Palen Mountains
and the Little Maria Mountains. Surrounded on three sides
by the Palen-McCoy wilderness, it is remote and primitive.
Driving south along Highway 78 from Blythe, past the
Cibola National Wildlife Refuge, one crosses Milpitas Wash.
Nearby, the Chocolate Mountains rise from the desert floor.
