Mount Whitney is the highest summit in the contiguous United States with an elevation of 14,505 feet (4,421 m). It is on the boundary between California's Inyo and Tulare counties, 84.6 miles (136.2 km) west-northwest of the lowest point in North America at Badwater in Death Valley National Park (282 feet (86 m) below sea level). The west slope of the mountain is in Sequoia National Park and the summit is the south end of the John Muir Trail which runs 211.9 miles (341.0 km) from Happy Isles in Yosemite Valley. The east slope is in the Inyo National Forest in Inyo County.
The summit of Whitney is on the Sierra Crest and near many of the highest peaks of the Sierra Nevada. The peak rises 10,778 feet (3,285 m) or just over two miles above the town of Lone Pine in the Owens Valley below.
Mount Whitney is above the tree line and has an alpine climate and ecology. Very few plants grow near the summit: one example is the Sky Pilot, a cushion plant that grows low to the ground. The only animals are transient, such as the butterfly Parnassius phoebus and the Gray-crowned Rosy Finch.
The estimated elevation of the summit of Mount Whitney has changed over the years. The technology of elevation measurement has become more refined and, more importantly, the vertical coordinate system has changed. The peak was commonly said to be at 14,494 feet (4,418 m) and this is the elevation stamped on the USGS brass benchmark disk on the summit. An older plaque on the summit (sheet metal with black lettering on white enamel) reads "elevation 14,496.811 feet" but this was estimated using the older vertical datum (NVGD29) from 1929. Since then the shape of the Earth (the geoid) has been estimated more accurately. Using a new vertical datum established in 1988 (NAVD88) the benchmark is now estimated to be at 14,505 feet (4,421 m).
The eastern slope of Whitney is far steeper than its western slope. This is because the entire Sierra Nevada is the result of a fault-block that is analogous to a door: the door is hinged on the west and is slowly rising on the east. The rise is caused by a normal fault system that runs along the eastern base of the Sierra, below Mount Whitney. Thus, the granite that forms Mount Whitney is the same as the granite that forms the Alabama Hills thousands of feet below. The raising of Whitney (and the downdrop of the Owens Valley) is due to the same geological forces that cause the Basin and Range Province: the crust of much of the intermontane west is slowly being stretched.
The granite that forms Mount Whitney is part of the Sierra Nevada batholith. In Cretaceous time, masses of molten rock that originated from subduction rose underneath what is now Whitney and solidified underground to form large expanses of granite. In the last few million years, the Sierra has started to rise. This has enabled glacial and river erosion to strip the upper layers of rock to reveal the resistant granite that makes up Mount Whitney today.
During the same expedition, geologist Clarence King attempted to climb Whitney from its west side, but stopped just short. In 1871, King returned to climb what he believed to be Whitney, but having taken a different approach, he actually summited nearby Mount Langley. Upon learning of his mistake in 1873, King finally completed his own first ascent of Whitney, but did so a month too late to claim the first recorded ascent.
A month earlier on August 18, 1873, Charles Begole, A. H. Johnson, and John Lucas of nearby Lone Pine, had become the first to reach the highest summit in the contiguous United States. As they were fishermen, they called the mountain Fisherman's Peak. But in 1891, the United States Geological Survey's Board on Geographic Names decided to recognize the earlier name of Mount Whitney. The name Whitney has remained, resisting a movement after World War II to rename the mountain for Winston Churchill.
Residents of Lone Pine financed the first trail to the summit, engineered by Gustave Marsh, and completed on July 22, 1904. Just four days later, the new trail enabled the first recorded death on Whitney. Having hiked the trail, U.S. Bureau of Fisheries employee Bryd Surby was struck and killed by lightning while eating lunch on the exposed summit. In response to this event, Marsh began work on the stone hut that would become the Smithsonian Institution Shelter, and completed it in 1909.
The most popular route to the summit is by way of the Mount Whitney Trail which starts at Whitney Portal (8,360 feet (2,550 m)) 13 miles (21 km) west of the town of Lone Pine. The hike is about 22 miles (35 km) round trip with an elevation gain of over 6,100 feet (1,900 m). Permits are required year round, and to prevent overuse a limited number of permits are issued by the Forest Service between May 1 and November 1. Most hikers do the trip in two days. Those in good physical condition sometimes attempt to reach the summit and return to Whitney Portal in one day, thus requiring only a somewhat easier-to-obtain "day use" permit rather than the overnight permit. This is considered an "extreme" day hike, which normally involves leaving Whitney Portal before sunrise and 12 to 18 hours of strenuous hiking, while struggling with altitude sickness, cold air, and occasionally treacherous surface conditions (because snow and/or ice are normally present on parts of the trail, except for a short period from early July to late September.)
Longer approaches to Whitney arrive at its west side, connecting to the Mount Whitney Trail near the summit by way of the John Muir Trail.
The fastest recorded time up this route to the summit and back to the portal is 3 hours 10 minutes, by Jason Lakey of Bishop.
The steep eastern side of the mountain offers a variety of climbing challenges. The East Face route, first climbed in 1931, is a classic route in the Sierra Nevada and involves technical free climbing (Class 5.7) but is mostly Class 4. Other routes range up to Class 5.10.
South of the main summit there are a series of minor summits that are completely inconspicuous from the west but appear as a series of "needles" from the east. The routes on these include some of the finest big-wall climbing in the high Sierra. Two of the needles were named after participants in an 1880 scientific expedition to the mountain. Keeler Needle was named for James Keeler and Day Needle was named for William Cathcart Day. The latter has now been renamed Crooks Peak after Hulda Crooks who hiked up Mount Whitney every year until well into her nineties.
