Near Mammoth Lakes in Mono County, California — The American West (Pacific Coastal)
The White Mountain Range, to the east, is the home of the bristlecone pines, the world's oldest living thing.
The banded light and dark colored formations of the Sierra Nevada was once sediment deposited by an ancient sea and is approximately 450 million years old.
This basin is a caldera, created by the collapse of a large volcano over 500,000 years ago. the collapse was preceded by violent and tremendous explosions known as nuees ardentes, which caused the catastrophic ejection of approximately 35 cubic miles of super-heated material over an area of 450 square miles. This resulted in the extensive tableland seen to the east and south which is known as the Bishop Tuff.
