  1. 1. Geology 3 Field assignment<br />A Journey Through the Magnificent Sequoias<br />By: Amanda Stone<br />*Photos of Sequoia National Park are from personal album<br />
  2. 2. The Sierra Nevada MountainsView from atop Moro Rock<br />Geography of the Sierra mountains<br />Present day<br />
  3. 3. The Sierra Nevada MountainsView from atop Moro Rock<br />How has it changed?<br />The uplift of the Sierra Nevada Mountains began relatively recently about 10 million years ago (NPS: http://www.nps.gov/seki/naturescience/geology_overview.htm)<br />Made up mostly of granitic (red) and metamorphic rock (blue), the Sierra Nevada formed mostly during the Mezozoic/Paleozoic, placing its origins around 500 to 65 million years old (Note 17, 2002)<br />150 million years ago the Nevadan mountains were the Western coast of the US and the seas only extended to the Eastern edges of the Central Valley (snobear.colorado.edu). This makes it easy to understand how sediment rich the valley is (or was). <br />
  4. 4. The Giant SequoiasSequoiadendrongiganteum<br />Present day<br />These beautiful giants are between 1800 and 2700 years old and grow up to 26 stories tall (http://www.nps.gov/seki/naturescience/bigtrees.htm)<br />
  5. 5. The Giant SequoiasSequoiadendrongiganteum<br />How has it changed?<br />Gymnosperms, like the sequoias, were present during the Jurassic and Cretaceous (Levin, 2006)<br />How seeds evolve<br />
  6. 6. Mule Deer<br />Present day<br />How many mule deer live in the park today?<br />Habits, appearance<br />Their impact on the environment<br />
  7. 7. Mule Deer<br />How has it changed?<br />Evolution of deer<br />Relationship to syndyoceras<br />
  8. 8. Huge Granite BatholithsView from in TokopahCanyon<br />Present day<br />About 210 mya the Nevadan Orogeny uplifted the ancient mountains generated enormous amounts of magma which formed these granite batholiths (Levin, 2006)<br />The forces pushing out these granitic rocks continued until about 90 million years ago. (snobear.colorado.edu)<br />Impact of glaciation on modern appearance (NPS)<br />
  9. 9. Huge Granite BatholithsView from in TokopahCanyon<br />How has it changed?<br />About 210 mya the Nevadan Orogeny uplifted the ancient mountains generated enormous amounts of magma which formed these granite batholiths (igneous rock) (Levin, 2006)<br />The forces pushing out these granitic rocks continued until about 90 million years ago. (snobear.colorado.edu)<br />
  10. 10. Present day<br />How many visitors to the park each day<br />Human impact on the park<br />Humans<br />
  11. 11. How has it changed?<br />Human evolution<br />What tribes existed long ago?<br />How did humans get to this area?<br />Humans<br />
