    • Field Trip 1
      Coso Volcanic Range
      Fossil Falls
      Mormon Rocks
    • Coso Volcanic Range
      Cinder Hill is one of the most prominent features in this range of young volcanoes. It is an example of a composite cinder cone and rises over a field of lava beds. One can find formations of intrusive basalt and extrusive lava flows. These signature volcanic features can be seen across the valley to the Sierra Nevada Mountains in the West and to the Inyo-White Mountains to the East.

      The two photos below show some more unique features in the volcanic area. On the left, an extrusive lava flow is circled. You can also see evidence of the landscape changing where the basalt has eroded away to form a gorge at the edge of the desert; and, the grasses growing in an intrusive basalt formation.

    • Fossil Falls
      Where the Owens River once flowed is a scarred ecosystem. One of the endangered “species”- water, actually became extinct in the floodplain. What it left behind were these amazing “fossils” of a former water fall, where the Owens once majestically dropped 200 feet before meandering to Owens Lake. The unique and beautiful shapes at Fossil Falls are due to the once rushing water pounding and smoothing the volcanic basalt.

    • Fossil Falls
      Before Los Angeles grew to be a major metropolis, the Owens River once flowed through here. Without running water some parts of the stream bed are beginning to fade into the surrounding landscape. However, this picture clearly shows the banks of the former flood plain.

    • Fossil Falls
      Examples of metate holes. These were created in the falls by rocks which were captured by a current subsequently weathering the basalt into a pot like hole.

    • Fossil Falls
      The area around Fossil Falls was inhabited by Paiute and Shoshone peoples. They lived a nomadic lifestyle, spending the warmer months in the Sierra foothills and the cooler months near the Owens River. Evidence of their native way of life can still be seen today.

      (drawings) can be
      found on rocks

    • Fossil Falls
      Shown here is the foundation for a Native dwelling, known as a house ring. When covered with reeds, this would have provided shelter for the hunter-gatherers.

    • Fossil Falls
      Among the stones found around Fossil Falls are many pieces of obsidian. This igneous rock is created when hot magma cools. It looks and feels like glass, and was used as a valuable tool by the Paiute and Shoshone. You can also see examples of other igneous rocks: basalt (black stones), scoria (red stones), pumice (inset).

    • Mormon Rocks
      Officially designated The Rock Candy Mountains, the more common name for these sandstone rock outcroppings is Mormon Rocks. These sandstone rock fault blocks are formed as the pressure of the N. American plate and Pacific slide past each other. The unique shape and pockmarked (inset) texture made this formation an easy “sign” to travelers ending their journey across the Mojave Desert and into the San Bernardino Valley The moniker honors the early Mormon settlers who found the route through Cajon Pass more pleasing than the original Mojave Indian Trail.

    • Mormon Rocks
      This photo shows a closer image of the granular structure of the Mormon Rocks. This sandstone is more resistant to weathering than the sediment rocks which were around it, making them a prominent geographic feature of the area.

    • Mormon Rocks
      This photo shows the stream bed of Cajon Wash – the seasonal river which flows past Mormon Rocks.
      Of interest, also, is the railroad bridge which crosses the river and suggests the flow of water here can be enough to disrupt our human landscape.

    • Mormon Rocks
      While this may look peaceful and iconic, you are actually viewing of photo of one of the most geologically active areas in the world. This is the place where the North American Plate and Pacific Plate meet and slid past one another. The action of this strike/slip, known as the San Andreas, created the rift valley below.

    • Diaz Lake
      Diaz Lake is a feature known as a sag pond. A sag pond is created when a large earthquake displaces land and causes it to sink. The land displaced by the 1872 earthquake was enough that the lake filled as Diaz Creek flowed into the sag. Several springs and run off from the nearby Alabama Hills also feed the lake.

    • Diaz Lake
      The area around Diaz Lake is representative of what the Owens Valley looked like prior to the export of its river water. This grove of Cottonwood trees is a tell that water is nearby. Also, in this picture are the Alabama Hills which trace to location of the Lone Pine Fault. The dark line along the base of the hills is the Los Angeles Aqueduct.

    • Mt. Whitney Interagency Visitor Center
      At 14, 505 feet, Mt. Whitney is the highest peak in the contiguous forty-eight United States. It is deceiving in the picture, as Mt. Whitney looks lower. However, this is caused by the near Lone Pine Peak looking taller.

      Sierra Nevada Range
      The Inyo-White Mountains form
      the eastern side of the Owens
      Valley. The key difference
      Between the Sierra Nevada and
      the White Mountains is their weathering.
      The “v”-shaped valley on the Whites indicate
      water erosion, while the “u”-shaped valleys
      on the Sierra Nevada indicate glacial erosion.

    • Keough’s Hot Springs
      The hot creek and pools is fed from a spring in the Alabama Foothills. The water is warmed underground through geothermal processes.

    • Mono Lake
      Mono Lake at one time covered nearly 1000 sq. miles. Through drought, evaporation, and recently, diversion Mono Lake currently covers about 66 sq. miles. Protected from diversion, three streams feed this terminal lake. Also, the two islands at the north shore provide a safe breeding ground for seagulls who feed on alkali flies and brine shrimp.

    • Mono Lake
      Mono Lake’s beauty and unique chemistry helped save it from the fate shared by many others in the Owens Valley. The lake and its watershed are protected and will continue to be an important Eastern California ecosystem.

    • Mono Lake
      Mono Lake is a terminal lake, meaning it has no natural outlet but evaporation. As lake levels dropped these amazing tufa formations were exposed. Tufas are created where a spring vents into the lake. The mixture of fresh water into the lake’s unique alkaline, saline, and arsenic rich water creates the otherworldly feature.

      I felt this was an interesting artifact because it demonstrates how little control over the local economy and ecology the residents of the Owens Valley have. Its unfortunate how they were taken advantage of by Los Angeles, and how the way of life was altered. I think that the lessons learned from the Owens River/LA Aqueduct should resonate for future generations and how important sustainability is to our survival as a culture and as humans.

    • Manzanar
      During WW II about 10,000 Americans of Japanese decent were ordered to this concentration
      camp for their safety and the fear of their threat to America.
      This would have been the location of the warehousing district inside Manzanar.
      There were dry and refrigerated storage facilities for imported and exported good.
      Manzanar was a working apple orchard.

    • SETI Site
      The Search for Extra-Terrestrial Intelligence Institute operates a site in the Owens Valley. The location far from civilization and between the Inyo-White and Sierra Nevada Ranges creates a sort of quiet zone for “listening at the stars.”
      Brandon Thrakulchavee
    • Water & Power
      The California Aqueduct brings water from Central California into the Inland Empire and is part of the tremendous effort by Southern Californian’s to supply this vital resource to the arid south. Other notable aqueducts in this system include the Los Angeles Aqueduct and the Colorado River Aqueduct.
      Part of the Owens River/L.A. Aqueduct system, is the development of geothermal- and hydro-power. The generated electricity is carried south power high tension power lines.

    • Cucamonga Alluvial Fan
      An alluvial fan is created at the base of ravine where water and runoff leave a mountain valley. Over time sediments are deposited to build this triangular feature at the foot of mountain ranges. The Cucamonga fan, a combination of several depository fans, at the base of the San Gabriel Mountains is the largest in California.
