Cinder HillCinder Hill is a cinder cone which is a mound “of basaltic scoria that forms by streaming gases that carry lava blobs and ribbons into the atmosphere to form lava fountains.” http://www.bing.com/images/search?q=lava+flows+cinder+hill%2C+CA&view=detail&id=CB5D5FA31F9EEB72C823CC8AABA6891359EC026D&first=1&FORM=IDFRIR
The lava blobs usually harden before they hit the ground.
Cinder Hill
The height of the cone is determined by the length of the eruption.
There are 21 composite volcanoes around Little Lake, CA . The last eruption occurred 500 years ago. Cinders are still seen in the soil around the volcanoes today.
Lava Flows
Lava flows move very slowly and are the least hazardous part of an eruption.
Cinder Rock
Orange Lichen Moss
Lichen moss slowly breaks down the rock it grows on and is a combination of moss and fungus.

Extras and Wildlife
Basalt forms created by quickly cooling lava emerging from an eruption.
Fossil Falls
Fossil Falls
Metate Hole
The rocks in fossil falls are made of basalt. During the ice age the Owens River flowed south out of Owens Lake. An eruption of the nearby volcanoes dammed up the river and flowed over the falls creating the shapes of rock you now see.
Metate holes are created by small rocks oscillating in place due to rapid running water.

Native American
“Workspace”
The obsidian flakes seen near Fossil Falls are actually signs of human life. Obsidian are actually big chunks of rock when they come out of the volcano but due to the Native Americans, that once inhabited the area, carving obsidian to use it for tools there are now millions of flakes of it everywhere.
This curved tall rock might have been the perfect shady workspace for tool production.

Petroglyphes
House Ring
Petroglyphes are carvings on rock walls of animals people and stories, in North America, carved by native Americans.
House rings are of what's left of Native American tipis; an area designated for their house surrounded by rocks.

Mormon Rocks
Granular Structure
Mormon Rock is not one solid rock, it actually consists of many different kinds of rock all embedded together from water flow during rainy seasons. As you can see, the granular structure has many “layers”. These layers show the amount of rain the area got that year depending on how many different rocks you see.
Sedimentary rocks are present due to the fault/earthquakes.

Dragon Lubber Grasshopper
Wildlife
The San Andreas Rift Zone is a natural stream bed that shows when the San Andreas slip fault has been active.
This fault is the boundary between the north and south plates of which are moving in opposite directions.
Diaz Lake
Diaz Lake
Lone Pine Fault
Diaz Lake was formed by the Lone Pine earthquake of 1872, opening a new spring and filling the area.
The 1872 Lone Pine earthquake on lone pine fault was one of the biggest recorded earthquakes to hit California.

Mt. Whitney
Inyo-White Mountains and Alluvial Fan
Mt. Whitney is the mountain in North America with an elevation 14,505 feet.
On the sides of the mountain are Sequoia National Park, Yosemite National Park, and Inyo National Park.
The Inyo Mountains separate Owens Valley and Saline Valley.
Alluvial fans are created by debris falling down the mountain side.
Keogh Hot Spring
The Keogh hot springs are the largest natural hot springs on the eastern side of the sierras.
Mono Lake
Former Shorelines
Tufa Formations
The ancient shoreline can be prominently seen at the base of the hills surrounding mono lake (the white line beneath them). The old shoreline is where all the bushes and vegetation cease before you get to the beach, and the current shoreline is seen where the water stops and land begins.
Mono Lake’s water is filled with sale and alkali so fish no longer live in it and birds are more scarce than before. There were cold and hot springs all around the lake and when fresh water would flow in from outside of the like and mix with the diluted water over time it created tufas, which are made of calcium carbonate and lime.

Convict Lake
Terminal Moraine
Convict lakeYellow: lateral moraineBlack: oldest rock formations in the sierras
Convict Lake was named after an incident in 1871 when a group of convicts escaped from prison and hid in the lake area.
The metamorphic rock layers are the oldest in the Sierras dating back almost 400 million years
Lateral moraines are lines of sediment deposited along the sides of a glacier and can run from the top of the glacier down to the bottom.
Terminal moraine is the sediment deposition furthest from the source of the glacier.

Bristlecone trees on top of the Inyo-White Mountains
Bristlecone trees are the oldest living organisms known today.
The swallows like to nest near water.
Benchmarks indicate the elevation of the area it is placed.

This is a slab of a Bristlecone Pine tree. I found it interesting because it shows how old it is by labeling major events in history with the grain in the wood.
Manzanar
Area where the main office used to be
Names and dates embedded in the stone circle
Manzanar was an internment camp for the Japanese during WW2 to keep both the country safe from potential domestic terrorism and violence against the Japanese-American people.
People relocated to the camp had to build their own houses and administrative buildings.
