You can also see that Mt Whitney is a part of the Inyo National Forest which covers an area of over two million acres. The Inyo National Forest not only contains Mt Whitney, but is also home to many beautiful landscapes such as Mono Lake, Mammoth Lakes Basin, and the Ancient Bristlecone Pine Forest located just to the east in the White Mountains. The Inyo National Forest also contains nine Congressionally-designated Wilderness areas, comprising over 800,000 acres of land. Most of the forest is in California but it includes about 60,700 acres in western Nevada. It stretches from the eastern side of Yosemite to south of Sequoia National Park.
