MORMON ROCKS
Bunna Roeum     The Mormon Rocks are a series of
                cemented sandstone beds much more
                resistant to erosion than the
                surrounding gravel and silt sands. The
                Mormon rocks lies right over the fault
                that divides the Pacific and North
                American plate and formed the rocks.In
                1851, a group of Mormon settlers led
                by Amasa M. Lyman and Charles C
                Rich traveled through the Cajon Pass in
                covered wagon on their way from Salt
                Lake City to Southern California. A
                prominent rock formation in the pass,
                where the Mormon trail and the railway
                merge.
GRANULAR STRUCTURE
Bunna Roeum



                         The Granular Structure The
                         Mormon Rocks are made up
                         of underlying sedimentary
                         rocks that have been pushed
                         through the eroded soil from
                         the San Gabriel Mountains.
SAN ANDREAS RIFT ZONE AND STREAM BED

                                     The San Andreas Rift zone is a
Bunna Roeum
                                     continental transform fault that
                                     runs a length of roughly 810 miles
                                     (1,300 km) through California in
                                     the United States. The fault's
                                     motion is right lateral strike slip
                                     (horizontal motion). It forms the
                                     tectonic boundary between the
                                     Pacific plate and the North
                                     American plate. The San Andreas
                                     rift zone It is located along the dirt
                                     /walkway you see in the picture to
                                     the left.
CINDER HILL
 Bunna Roeum




               Red Hill,or Cinder Hill is a basaltic
               cinder cone type of Volcano located
               in the Coso Volcanic field near
               Fossil Falls State Park
LAVA FLOW
            Lava flows are streams of
            molten rock that pour or ooze
            from an erupting vent. Lava is
            erupted during either
            nonexplosive activity or
            explosive lava fountains. Lava
            flows destroy everything in their
            path, but most move slowly
            enough that people can move
            out of the way.
STREAM BED
FOSSIL FALLS
Bunna Roeum    •   During the last ice age the glaciers
                   had fomred in the Sierra Nevade. The
                   meltwater from the glaciers pooled into
                   lakes including Ownes Lake and the
                   Owens River. The river had traveled
                   through to Indian Wells Valley. Fossil
                   falls were formed when the river was
                   forced to divert its course over a basalt
                   flow, polishing and reshaping the rock
                   into a varitety of uniques shapes and
                   forms. All of the lava flows at fossil
                   falls are basaltc.
METATE HOLES




• Metate holes were created when pieces of debris would drill into the
  basalt from the former water flow and would spin and create the
  metate holes
OBSIDIAN FLAKES
                   •   Flakes of obsidian can be found
Bunna Roeum            in the area, for the Native
                       Americans would camp near
                       Fossil Falls and chip obsidian
                       from the Coso Mountains to
                       form their tools. Remains of rock
                       foundations from their homes
                       and obsidian chips from too
                       lmaking are evidence of various
                       occupations of this site between
                       12,000 and 3,000 years ago.
                       Obsidian flakes are a result from
                       the Volcanic glass.
PETROGLYPH
             •   The Indians who lived in this fossil
                 falls site were the ones who had
                 carved these animals/petroglyphs
                 pictured on the rock.
             •   Petroglyphs are also known as
                 rock engravings. Petroglyphs are
                 found worldwide and are often
                 associated with prehistoric people.
             •   Petroglyphs are rock carvings left
                 by the indians who came before us
                 and had told stories by engraving
                 them onto the rocks.
HOUSE RINGS

              • House rings were former
                homes for the Native
                Americans. The native
                Americans would stay here
                during the summer for cooler
                climates and during the winter
                would migrate to the flatter
                lands during the winter.
TRIP TWO
       NORTHERN OWENS VALLEY
EASTERN SIERRA/LONE PINE/MANZANAR/ DIAZ
     LAKE/ MONO LAKE/CONVICT LAKE
                4/13/2012
DIAZ LAKE
Bunna Roeum               Diaz Lake was created
              Diaz Lake
                          from and Earthquake
                          along the Lone Pine
                          Fault in 1872. This kind
                          of lake is known as a
                          Sag Pond. The
                          earthquake caused the
                          land to sink and the
                          sunk water filled up the
                          pond creating Diaz lake.
Bunna Roeum
                         Lone pine fault




 •   In 1872 the large earthquake was caused by a vertical and right lateral
     displacement along the lone pine fault. The earthquake caused the fault to move
     back and created diaz lake.
MONO LAKE
Bunna Roeum
ISLANDS AT MONO LAKE
Bunna Roeum
                             Paoha Island
                                                           Negit island




Paoha Island located on the left of this slide is a volcanic island that was formed in the 17th
century. The Negit Island is considered a volcanic cone. Negit island is dark because it was
composed by lava flows.
TUFA FORMATIONS
Bunna Roeum


                      tufa




When calcium rich springs flow up through the lake bottom the calcium bonds to
carbonates in the lake water. Together they form calcium carbonate, a type of limestone.
This solid material builds on itself forming a tufa tower. When the Lake level drops the
exposed tufa stops growing.

  • 3. MORMON ROCKS Bunna Roeum The Mormon Rocks are a series of cemented sandstone beds much more resistant to erosion than the surrounding gravel and silt sands. The Mormon rocks lies right over the fault that divides the Pacific and North American plate and formed the rocks.In 1851, a group of Mormon settlers led by Amasa M. Lyman and Charles C Rich traveled through the Cajon Pass in covered wagon on their way from Salt Lake City to Southern California. A prominent rock formation in the pass, where the Mormon trail and the railway merge.
  • 4. GRANULAR STRUCTURE Bunna Roeum The Granular Structure The Mormon Rocks are made up of underlying sedimentary rocks that have been pushed through the eroded soil from the San Gabriel Mountains.
  • 5. SAN ANDREAS RIFT ZONE AND STREAM BED The San Andreas Rift zone is a Bunna Roeum continental transform fault that runs a length of roughly 810 miles (1,300 km) through California in the United States. The fault's motion is right lateral strike slip (horizontal motion). It forms the tectonic boundary between the Pacific plate and the North American plate. The San Andreas rift zone It is located along the dirt /walkway you see in the picture to the left.
  • 6. CINDER HILL Bunna Roeum Red Hill,or Cinder Hill is a basaltic cinder cone type of Volcano located in the Coso Volcanic field near Fossil Falls State Park
  • 7. LAVA FLOW Lava flows are streams of molten rock that pour or ooze from an erupting vent. Lava is erupted during either nonexplosive activity or explosive lava fountains. Lava flows destroy everything in their path, but most move slowly enough that people can move out of the way.

Fossil falls were formed when the river was forced to divert its course over a basalt flow, polishing and reshaping the rock into a varitety of uniques shapes and forms. All of the lava flows at fossil falls are basaltc.
  • 10. METATE HOLES • Metate holes were created when pieces of debris would drill into the basalt from the former water flow and would spin and create the metate holes
  • 11. OBSIDIAN FLAKES • Flakes of obsidian can be found Bunna Roeum in the area, for the Native Americans would camp near Fossil Falls and chip obsidian from the Coso Mountains to form their tools. Remains of rock foundations from their homes and obsidian chips from too lmaking are evidence of various occupations of this site between 12,000 and 3,000 years ago. Obsidian flakes are a result from the Volcanic glass.
  • 12. PETROGLYPH • The Indians who lived in this fossil falls site were the ones who had carved these animals/petroglyphs pictured on the rock. • Petroglyphs are also known as rock engravings. Petroglyphs are found worldwide and are often associated with prehistoric people. • Petroglyphs are rock carvings left by the indians who came before us and had told stories by engraving them onto the rocks.
  • 13. HOUSE RINGS • House rings were former homes for the Native Americans. The native Americans would stay here during the summer for cooler climates and during the winter would migrate to the flatter lands during the winter.

  • 15. DIAZ LAKE Bunna Roeum Diaz Lake was created Diaz Lake from and Earthquake along the Lone Pine Fault in 1872. This kind of lake is known as a Sag Pond. The earthquake caused the land to sink and the sunk water filled up the pond creating Diaz lake.
  • 16. Bunna Roeum Lone pine fault • In 1872 the large earthquake was caused by a vertical and right lateral displacement along the lone pine fault. The earthquake caused the fault to move back and created diaz lake.
  • 18. ISLANDS AT MONO LAKE Bunna Roeum Paoha Island Negit island Paoha Island located on the left of this slide is a volcanic island that was formed in the 17th century. The Negit Island is considered a volcanic cone. Negit island is dark because it was composed by lava flows.
  • 19. TUFA FORMATIONS Bunna Roeum tufa When calcium rich springs flow up through the lake bottom the calcium bonds to carbonates in the lake water. Together they form calcium carbonate, a type of limestone. This solid material builds on itself forming a tufa tower. When the Lake level drops the exposed tufa stops growing.
