Fossil Falls Stream Bed Fossil Falls Stream Bed. Where water from Owens River use to flow. October 9, 2010. 2:47 pm.
Fossil Falls Fossil Falls was formed from melt water from glaciers, that pooled into lakes, including Owens lake and river. The falls were formed when the river was forced to divert its course over a basalt flow, polishing and reshaping the rock into a variety of unique shapes and forms. October 9, 2010. 2:44 pm.
Metate Holes Metate holes at Fossil Falls were used by the Native Americans to grind up acorns or other foods. October 9, 2010. 2:24 pm.

San Andreas Rift Zone The San Andreas Rift Zone is a continental transform fault that runs a length of roughly 810 miles through California. The fault's motion is right-lateral strike-slip. It forms the tectonic boundary between the Pacific Plate and the North American Plate. October 9, 2010. 10:19 am. Rift Zone
Mt. Whitney & inyo- white mts. Mt. Whitney is the highest summit in the U.S. The granite that forms Mount Whitney is part of the Sierra Nevada batholiths. In Cretaceous time, masses of molten rock that originated from subduction that rose underneath what is now Whitney and solidified underground to form large expanses of granite. In the last few million years, the Sierra has started to rise. This has enabled glacial and river erosion to strip the upper layers of rock to reveal the resistant granite that makes up Mount Whitney today. November 5, 2010. 1:46 pm. Mt. Whitney
Diaz Lake Diaz Lake was formed in 1872 by the Lone Pine Earthquake. Eighteen miles of the Owens Valley dropped approximately 20ft, causing a new spring to open and , causing water to fill the lowland. November 5, 2010. 1:28 pm.
Lone Pine Fault The Lone Pine Fault is part of a twin system of normal faults that run along the base of two parallel mountain ranges; the Sierra Nevada on the west and Inyo Mountains on the east flank of Owens Valley. The Lone Pine fault helped generate one of the largest earthquakes in California in 1872, with the epicenter near Lone Pine. November 5, 2010. 1:27 pm. Lone Pine Fault
Manzanar The Lone Pine Fault is part of a twin system of normal faults that run along the base of two parallel mountain ranges; the Sierra Nevada on the west and Inyo Mountains on the east flank of Owens Valley. The Lone Pine fault helped generate one of the largest earthquakes in California in 1872, with the epicenter near Lone Pine. November 5, 2010. 1:27 pm.
Mono Lake and Islands Negit Paoha Mono Lake is believed to have been formed by the Long Valley eruption. In order to provide water needs for the growing City of Los Angeles, water was diverted from the Owens River into the Los Angeles Aqueduct in 1913. In 1941 the Los Angeles Department of Water and Power extended the Los Angeles Aqueduct system further upriver into the Mono Basin. So much water was diverted that evaporation soon exceeded inflow and the surface level of Mono Lake fell rapidly. By 1982 the lake was reduced to 37,688 acres, losing 31 percent of its 1941 surface area. As a result alkaline sands and once-submerged tufa towers became exposed and Island became land bridged, exposing the nests of gulls to predators and forcing the breeding colony to abandon the site. It has an unusually productive ecosystem, and is a critical nesting habitat for several bird species. November 6, 2010. 11:27 am.
Mono Lake former shore lines Mono lakes shorelines have changed over the years because of water being diverted from the Los Angeles aqueduct. Former shore line
Tufa Tufa is a variety of limestone, formed by the precipitation of carbonate minerals from ambient temperature water bodies. The tufa at Mono Lake were formed underwater and then exposed as the water level of Mono Lake began to fall, exposing the tufa. The tufa provided nesting area for birds and other animals.
Panum Crater Panum Crater is a volcanic cone that is part of the Mono-Inyo Craters. Panum Crater formed in a sequence of events. The first event was caused by magma rising from deep within the Earth's crust. When this extremely hot, liquid rock made contact with water just below the surface, the water expanded into steam and a large, violent eruption occurred. So much debris was blown out that a gaping crater was left behind. November 6, 2010. 12:31 pm.
Keoughs Hot spring Keoughs Hot Springs were produced by the emergence of geothermally heated groundwater from the Earth's crust. November 5, 2010. 3:50 pm.
Convict Lake Convict Lake gets its name from a hanging that took place in 1871. The mountains surrounding convict lake have some of the oldest formations of rocks. November 6, 2010. 4:30pm. Lateral & Terminal Moraine Oldest formation of rocks
Grant lake Grant Lake is a man made lake that was a dam before it became a reservoir for the LADWP. November 6,2010. 3:30 pm
Waterfall & Moraines The water fall near Silver Lake cascade s into Silver Lake and Rush Creek. These moraines were glacially formed and by accumulation of unconsolidated glacial debris (soil and rock) which can occur in currently glaciated and formerly glaciated regions, such as those areas acted upon by a past ice age. November 6, 2010. 3;42 pm. Moraines Waterfall
Silver lake Silver Lake is found in the June Lake Loop. The overflow from June lake and Gull Lake flows back toward the mountain range and thus is named Reversed Creek. Reversed Creek reaches a confluence with Rush Creek and flows through Silver Lake and Grant Lake, completing the "loop" to the Mono Basin. November 6, 2010. 3:41 pm
Cucamonga Alluvial Fan The Cucamonga Alluvial Fan was formed by the outwash of streams draining the southern slopes of the eastern part of the San Gabriel Mountains, in the Cucamonga and San Bernardino quadrangles. Photo credit to Aaron Bratton. Date and time unknown. Alluvial Fan
Eastern California museum I picked these shoes from the 1860’s because I found it interesting that at the time these shoes were made they were made to fit either the left or the right foot. It wasn’t until after the civil war that shoes were mass produced specifically for left and right feet. November 7, 2010. 10:20 am.
Solar power plant & Doppler Radar tower The solar power plants in the Mojave Desert supply power to the electricity grid. Solar Energy Generating Systems is the name given to nine solar power plants in the Mojave Desert which were built in the 1980s. October 9, 2010. 11:49 am. The Doppler Radar is a specialized radar that makes use of the Doppler effect to produce velocity data about objects at a distance. These Doppler tower in the desert provide info for weather in California. October 9, 2010. 11:54 am.
Mine tailings & the garlock fault Garlock Fault Mine Tailings Mine tailings are the materials left over after the process of separating the valuable fraction from the uneconomic fraction of an ore. October 9, 2010. 12:20pm. The Garlock Fault is a left-lateral strike-slip fault running approximately northeast-southwest in southern California for much of its length along the southern base of the Tehachapi Mountains. It marks the northern boundary of the area known as the Mojave Block, as well as the southern ends of the Sierra Nevada and the valleys of the westernmost Basin and Range province.

California Aqueduct &Owens dry lake Owens Dry Lake The California Aqueduct is a system of canals, tunnels, and pipelines that conveys water collected from the Sierra Nevada Mountains and valleys of Northern- and Central California to Southern California. October 9,2010. 12:14 pm. Owens Dry Lake is a mostly dry lake in the eastern Sierra Nevada of Inyo County, California, located about 5 miles south of Lone Pine, California. Unlike most dry lakes in the Basin and Range Province that have been dry for thousands of years, Owens held significant water until 1924, until much of the Owens River was diverted into the Los Angeles Aqueduct, causing it to desiccate. Today, some of the flow of the river has been restored, and the lake now contains some water. November 5, 2010. 1:07 pm.
Joshua tree, creosote, & burroweed grass Joshua Tree Creosote Bush Burroweed Grass Joshua trees are fast growers, if it survives the rigors of the desert it can live for hundreds of years with some specimens surviving up to a thousand years. Creosote bush is most common on the well-drained soils of alluvial fans and flats. Burroweed is a member of the Sunflower Family. The rounded shrub grows to 3 feet in height and has green, deeply lobed leaves that grow on alternate sides of the stem.. The plant typically grows in dry, gravelly to sandy soils on roadsides, waste places, alluvial plains, mesas, and slopes. October 9, 2010. 11:15 am.
