Field assignment the scoop in lake tahoe

  1. 1. The Scoop on the History of Lake Tahoe Allyssa Little Summer 2013 GEL 103-01 Professor Lawler
  2. 2. Geology of Lake Tahoe • The Lake tahoe basin is considered to be anywhere around the lake that you could see the lake. (Bowl shape) • The Lake Tahoe basin was formed by geologic block faulting (normal). • A geologic block fault is a fracture in the Earth's crust causing chunks of land to move up or down. • Formed about 2-3 million years ago
  3. 3. Geology of Lake Tahoe Cont. • Snow, rain and streams eventually filled the lowered section of land which made the ancestral Lake Tahoe • Modern Lake Tahoe was shaped by glaciers moving and melting during the Great Ice Age • Lake Tahoe is the second deepest lake in the United States, with its lowest point being lower in sea level than Carson City NV • It is the tenth deepest in the world
  4. 4. Rocks found in the Lake Tahoe Basin This is Granite. The main type of rock found in the basin. This is an igneous rock. The small rocks were formed when the glacier was moving through breaking off parts of the mountains. This is the most common type of granite you will see. Grey/White with Black spots.
  5. 5. Rocks found in the Lake Tahoe Basin This is granite an igneous rock. Although granite is igneous by nature, it can also be metamorphic. The rock on the left. Collections of minerals began to grow in magma and continued to develop as the magma quickly cooled. Making it metamorphic. When on trails in the area, you will be able to see the differences in these types of rocks.
  6. 6. Rocks found in the Lake Tahoe Basin This is granite as well, an igneous rock. There is more color in this rock because of a couple possible reasons: • High levels of iodine in the creek beds • When the water runs over the rock and the sun hits it, greens and yellows even creep out. Lake Tahoe is a beautiful and magical geological place.
  7. 7. Animals in the Lake Tahoe Basin This is a bald eagle, a bird of prey. The bald eagle lives in Lake Tahoe as well as many other parts of the country. They like to live by water. The bald eagle’s diet mainly consists of fish. Swooping down and catching the fish in water. There are two sub species of the bald eagle. The Bald Eagle is the National Animal and National Bird of the USA.
  8. 8. Animals in the Lake Tahoe Basin This is the Raccoon. The raccoon is native to North America. Raccoons are very prominent critters in Lake Tahoe. The original habitats of the raccoon were mainly deciduous and mixed forests; however, they are very adaptable and can live in much harsher climates. They are survivors probably because of their excellent ability to scavenge. My trash is constantly being eaten by a raccoon.
  9. 9. A plant from the Lake Tahoe Basin This is the Shasta Daisy. The scientific name is Leucanthemum superbum. This daisy is named after Lake Shasta because the petals were the color of the snow. This plant is a flowering perennial plant meaning it has flowers and it comes back every year. This plant grows incredibly well in Lake Tahoe. They are study plants that can take the cold more than most.
