 and loss was not taken into consideration. It is estimated that, when hiking north to south, the amount of ascent of the JMT is just over 46000 feet (14,020.8 m) and the total descent is just over 38000 feet (11,582.4 m), for a total of about 84000 feet (25,603.2 m), or almost 16 miles (25.7 km); however, this does not mean the total length is increased by 16 miles (25.7 km).

History

The idea of the trail along the backbone of the High Sierra originated with Theodore Solomons
Theodore Solomons
Theodore Seixas Solomons was an explorer and early member of the Sierra Club. From 1892 to 1897 he explored and named the Mount Goddard, Evolution Valley and Evolution Basin region in what is now northern Kings Canyon National Park in eastern California...

. Solomons later recalled that the concept originated in his adolescence. "The idea of a crest-parallel trail came to me one day while herding my uncle's cattle in an immense unfenced alfalfa field near Fresno. It was 1884 and I was 14." He began advocating construction of the trail shortly after the Sierra Club

, he pioneered a high mountain route in 1908 from Yosemite National Park to Kings Canyon, roughly along the route of the modern JMT. In 28 days, they completed a trip of 228 miles through the high mountains, including several previously unexplored sections. In 1914, the Sierra Club appointed a committee to cooperate with the State of California to begin construction of the trail. John Muir died later that year, and the proposed trail was renamed in his honor.

Construction of the JMT began a year after Muir's death in 1915 with a $10,000 grant from the California legislature. State Engineer Wilbut F. McClure was responsible for selecting the final route. He secured the cooperation of the United States Forest Service

, which managed and supervised much of the actual construction. The California state legislature made additional appropriations of $10,000 each in 1917, 1925, 1927 and 1929.

After the Depression began, assistance from the California state government came to an end, and there were still two difficult sections yet to be completed. One was the connection from the Kings River to the Kern River over Forester Pass, at an elevation of 13153 feet (4,009 m). The Forester Pass section was completed in 1932 as the result of a joint effort between the Forest Service and the National Park Service

) in 1938. This section passes by the headwaters of the Middle Fork of the Kings River and over Mather Pass by the "Golden Staircase" to the headwaters of the South Fork of the Kings River.

. Backpackers travelling at a generous pace usually complete the trail within three weeks.

A permit is required to hike the JMT, which is obtained from the national park or forest where the hiker begins the hike. This single permit is valid for the entire hike. Permits can be hard to obtain for JMT thru-hikers. Both ends of the JMT, Yosemite and Whitney Portal have a lottery for wilderness permits. In addition, in Yosemite hikers face competition with other backpackers simply wanting to camp overnight while hiking Half Dome or to Tuolumne Meadows. Backpackers

, which are common in the region.

About 75-90 percent of hikers hike north to south, from Yosemite Valley to Mt. Whitney. There are advantages to starting in Yosemite Valley and hiking south. Although there is a significant net altitude gain this way, starting at a lower altitude allows the hiker time to acclimatize to the elevations of the trail rather than immediately having to tackle a 6,000-foot (1,800 m) climb to the summit of Mount Whitney. In addition, there are several resupply points convenient to the JMT during its northern half (Tuolumne Meadows, Reds Meadow, Vermillion Valley Resort, Muir Trail Ranch), allowing the hiker to carry a lighter food load early in the hike and also to exit the trail easily if problems arise. The southern half of the JMT is more remote and generally higher in elevation, thus making it more appropriate for the second half of the hike when maximum conditioning has been attained.
