  • 1. Field Trip Journal
    Adela Lopez
    Professor Schmidt
    Chino, Mondays @ 1
    Geography 5
    Section 63650
  • 2. Mormon Rocks- Trip #1 March 12, 2011 9:30- 11:00am
  • 3. Mormon Rock
    Formation
    Stream bed/San Andreas rift Zone
    Mormon Rocks “rock candy”
    Mormon Rocks Formation- When faults move (earthquakes or seismic activity)bottom of stream bed is picked up and the rocks begin to form.
    Stream Bed/ San Andreas Rift Zone- dried up river, and the clashing of san Bernardino and San Gabriel mountains because of tectonic plates **Train Passing through
  • 4. Granular Structure
    We can see the levels as they are formed in layers. Depending on the size of the layers and the amount and size of debris and rocks we are able to find out the amount of precipitation that year.
    This is a very small but great example of how the giant Mormon rocks start to form. On this 10 ft wall. You can see the layers of sandstone start to build up and how high the water reaches at times in this dried up river during our rain season.
    Thick layer =lots of rain
    Water line of recent precipitation
  • 5. Granular Structure & Mormon Rocks
    Big wholes are formed because of the constant wind and because over time the rocks or giant boulders fall out.
    Dried up waterfall
    Small hole, where rock fell out
    Water line of a recent waterfall, no longer there at time of field trip
  • 6. Field Trip #2-April 8, 2011
    Around noon
  • 7. StreamBed
    Little Lake Dry stream bed
    Once called “Owens Little Lake “
  • 8. Fossil Falls
    Little Owens lake flowed through here once until the volcanic lava disturbed and changed the direction of the streams.
    40 FT. dry water fall
  • 9. Fossil Falls & Metate Holes
    Fossil Falls
    Metate Holes: were used by woman to crack the shells off nuts and plant seeds.
  • 10. ObsidianFlakes
    Volcanic glass that was used to make arrowheads and other tools
  • 11. Petro glyph
  • 12. HousErinGs
    These rings were the foundation of their homes, which were covered with animal skins and grass and brush maybe.
    Entrance to ring
    HouseRing
  • 13. Cinder Hill
    Cinder hill is a result of a violent eruption of trapped gases and molten material from a vent in the earths crust.
    As the material cooled quite fast after air hit it, the hill was formed called Scoria
  • 14. Lava Flows
    440,00 years ago the Coso Mountain range was an active chain of volcanoes that erupted a number of times . Slow flowing dark lava called Basalt.
  • 15. Keoughs Hot Springs
    The hot springs are warm springs that are formed because of the faults that have left cracks and when the water gets in the cracks and comes up making the water warm
    Hi!!
  • 16. Mono Lake Committee Visitors Center
    April 9, 2011 around 11:00am
  • 17. Mono Lake Committee Visitors Center
    You can come here to learn some history about Mono Lake
  • 18. Mono Lake
    April 9, 2011
    Around noon
  • 19. Lake and Islands
    Negit Island
    Black point
    Mono lake
    “Sea of the desert”
  • 20. Mono Lake former shore lines
    In 1963 the elevation of the lake was at 6392 ft.
    This deck was built in order to set a goal of where Mono lakes water should rise too.
  • 21. Mono Lake
    Former Shore lines
  • 22. Tufa
    Tufa is formed where there was once a hot water spring under water, the bubbles that come through up to the surface.
  • 23. Glaciated Valley and Moraines
    Panum Crater
    Glaciated Valley
  • 24. Convict Lake
    April 9, 2001
    Around 3:00pm
  • 25. Convict Lake and Oldest rock formation
  • 26. Lateral and Terminal Moraines
  • 27. Owens River
    April 9, 2011
    Around 5:30 pm
  • 28. Owens River & Swallows Nests
    This river used to flow into Owens Lake but it has been transitioned to California and LA aqueduct.
  • 29. Inyo-White Mountains with Bristlecones
    Benchmark
    Oldest Trees on earth and only ones left.
  • 30. Extra Credit
    Solar Power Plant
    Doppler Radar Tower
  • 31. Extra Credit
    Mine Tailings
    Joshua trees
  • 32. Extra Credit
    Dry Owens Lake
    SETI TOWERS
  • 33. Field Questions
    Mormon Rocks Formation-
    This are is very important because this is where the Andreas Fault is and where a lot of seismic activity and earthquakes start.
    The rocks are formed when there is a earthquake the bottom of the stream bed is then inverted and starts to form the rocks upward the oldest rocks being at the top. The rocks are formed because the water from the stream picks up all the debris and rocks and then it dries with the intense heat and cold desert temperatures.
    2. Cinder (red) Hill/Fossil Falls
    I saw the red cinder hill, red cinder all over the ground, the Lava rock formations, the house rings, and Fossil falls which are very high up.
    3 things that show evidence of Native American habitation are the pyroglyphs, house rings and the broken obsidian.
  • 34. Field Questions
    Mt. Whitney Interagency Center
    A. The Sierra Nevada Mountains are shaped in a “U” form because they are made by glaciers and the Inyo/White Mountains are “V” shaped because water has been a main ingredient to their formation.
    4. Analema- On April 9th the sub solar angle was at 60 degrees North.
    5. Mono Lake-
    The land forms I saw at Mono Lake were the Tufa’s, Islands, volcanoes.
    3 evidences of former lake levels:
    Tufa’s that are far away from the water away from the shore lines which had to grow in the actual water.
    You can see the water levels on the mountains surrounding the lake.
    The wooden panels of where the deck was connected to the water.
