Mountain Range Along California's Eastern Border

The Sierra Nevada runs the length of California's eastern border, stretching about 400 miles (640 km) from the Klamath Mountains in the north to the Tehachapi Mountains in the south. Its highest peak, Mount Whitney (14,505 ft / 4,421 m), is also the tallest mountain in the contiguous United States. The range is a premier destination for hiking, camping, fishing, and skiing.
