Great Basin protects 77,000 acres of the central Nevada high desert anchored by Wheeler Peak — at 13,063 ft, the second-highest mountain in Nevada and the centerpiece of the only mountain range in the state with a Pleistocene glacier still active in its cirque. The park is famous for three features: the Lehman Caves marble cavern system at the base of Wheeler Peak, the bristlecone pine groves above 10,000 ft (containing trees over 4,500 years old — among the oldest known living things on earth), and some of the darkest measured night skies in the contiguous US. The park is genuinely remote — the access road, US-50, is officially nicknamed "the Loneliest Road in America." From I-15 the standard route is Exit 174 in Holden, UT, then 175 mi west on US-50 to Baker, NV; from I-80 in Wendover, US-93A south is shorter (135 mi) but less commonly used.
