Human habitation in the Sierra Nevada region of California reaches back 8,000 to 10,000 years ago. Historically attested Native American populations, such as the Sierra Miwok, Mono and Paiute, belong to the Uto-Aztecan and Utian phyla. In the mid-19th century, a band of Native Americans called the Ahwahnechee lived in Yosemite Valley. The California Gold Rush greatly increased the number of non-indigenous people in the region. Tensions between Native Americans and white settlers escalated into the Mariposa War. As part of this conflict, settler James Savage led the Mariposa Battalion into Yosemite Valley in 1851, in pursuit of Ahwaneechees led by Chief Tenaya. The California state military forces burned the tribe's villages, destroyed their food stores, killed the chief's sons, and forced the tribe out of Yosemite. Accounts from the Mariposa Battalion, especially from Dr. Lafayette Bunnell, popularized Yosemite Valley as a scenic wonder.
In 1864, Yosemite Valley and the Mariposa Grove of giant sequoia trees were transferred from federal to state ownership. Yosemite pioneer Galen Clark became the park's first white guardian. Conditions in Yosemite Valley were made more hospitable to non-indigenous people, and access to the park was improved in the late 19th century. Indigenous people continued to be forced out periodically, while white settlers were paid a total of $60,000 to move out of the valley. Naturalist John Muir and others became increasingly alarmed about the excessive exploitation of the area. Their efforts helped establish Yosemite National Park in 1890. Yosemite Valley and the Mariposa Grove were added to the national park in 1906.
The United States Army had jurisdiction over the national park from 1891 to 1914, followed by a brief period of civilian stewardship. The newly formed National Park Service took over the park's administration in 1916. Improvements to the park helped to increase visitation during this time. Preservationists led by Muir and the Sierra Club failed to save Hetch Hetchy Valley from becoming a reservoir when the Raker Act was approved on December 2, 1913. This event was considered a major conservation battle lost, after which John Muir gave up on fighting and died on December 24, 1914. Construction on the O'Shaughnessey Dam began in 1919 and was completed in 1923. The loss of Hetch Hetchy led to the formation of the National Park Service through the approval of the Organic Act of 1916. In 1964, 89 percent of the park was set aside in a highly protected wilderness area, and other protected areas were added adjacent to the park.
Early history
Native Americans Humans may have lived in the Yosemite area as long as 8,000 to 10,000 years ago. Habitation of the Yosemite Valley proper can be traced to about 3,000 years ago, when vegetation and game in the region was similar to that present today; the western slopes of the Sierra Nevada had acorns, deer, and salmon, while the eastern Sierra had pinyon nuts and obsidian. Native American groups traveled between these two regions to trade and raid.
Archaeologists divide the pre-European American contact period of the region into three cultural phases. The Crane Flat phase lasted from 1000 BCE to 500 CE and is marked by hunting with the atl atl and the use of grinding stones. The Tarmarack phase lasted from 500 until 1200, marked by a shift to using smaller rock points, indicating development and use of the bow and arrow. The Mariposa phase lasted from 1200 until contact with European Americans.
Trade between tribes became more widespread during the Mariposa phase, and the diet continued to improve. Paiutes, Miwok, and Monos visited the area to trade; one major trading route went over Mono Pass and through Bloody Canyon to Mono Lake in Eastern California.
Paiutes were the primary inhabitants of the Yosemite area and the foothills to the east during the Mariposa and historic phases. The Central Sierra Miwoks lived along the drainage area of the Tuolumne and Stanislaus Rivers, while the Paiutes inhabited the upper drainage of the Merced and Chowchilla Rivers.
The Paiutes of Yosemite Valley called themselves the Ah-wah-ne-chee, meaning "dwellers in Ahwahnee." The Ahwahneechees were decimated by a disease in about 1800, and left the valley, although about 200 returned under the leadership of Tenaya, son of an Ahwahneechee chief.
Displaced Native Americans from the Californian coast moved to the Sierra Nevada during the early-to-mid-19th century, bringing with them their knowledge of Spanish food, technology, and clothing. Joining forces with the other tribes in the area, they raided land grant ranchos on the coast and drove herds of horses to the Sierra, where horse meat became a major new food source.
Exploration by European Americans Although there were Spanish missions, pueblos (towns), presidios (forts), and ranchos along the coast of California, no Spanish explorers visited the Sierra Nevada. The first European Americans to visit the mountains were amongst a group led by fur trapper Jedediah Smith, crossing north of the Yosemite area in May 1827, at Ebbetts Pass.
A group of trappers led by mountain man Joseph Reddeford Walker may have seen Yosemite Valley in the autumn of 1833. Walker approached a valley rim as he led his party across the Sierra Nevada, but he did not enter it. A member of the group, Zenas Leonard, wrote in his journal that streams from the valley rim dropped "from one lofty precipice to another, until they are exhausted in rain below. Some of these precipices appeared to us to be more than a mile high." The Walker party probably visited either the Tuolumne or Merced Groves of giant sequoia, becoming the first non-indigenous people to see the giant trees, but journals relating to the Walker party were destroyed in 1839, in a print shop fire in Philadelphia.
The part of the Sierra Nevada where the park is located was long considered to be a physical barrier to European American settlers, traders, trappers, and travelers. That situation changed in 1848 after gold was discovered in the foothills west of the range. Travel and trade activity dramatically increased in the area during the ensuing California Gold Rush. Resources depended upon by local Native Americans were depleted or destroyed, and disease brought by the newcomers spread rapidly through indigenous populations. Extermination of native culture became a policy of the United States Government.
The first confirmed sighting of Yosemite Valley by a non-indigenous person occurred on October 18, 1849, by William P. Abrams and a companion. Abrams accurately described some landmarks, but it is uncertain whether he or his companion actually entered the valley. In 1850, one of three brothers, Joseph, William, or Nathan Screech, became the first confirmed non-indigenous person to enter Hetch Hetchy Valley. Joseph Screech returned two years later and spoke with the Native Americans living there, asking them what the name of a grass-covered seed meal was and was told, "hatch hatchy."
The surveying crew of Allexey W. Von Schmidt conducted the first systematic traverse of any part of the Yosemite area backcountry in 1855, when it extended an approximation of the Mount Diablo Baseline eastward from a point west of the present park boundary, to a point south of Mono Lake. The actual route taken was 5 to 6 miles south of the actual baseline, due to topographic difficulties, including the Tuolumne River canyon at low elevations, and steep mountain slopes higher up. This was the first straight line survey made across the Sierra Nevada From 1879 to 1883 large parts of the western half of the park were surveyed as part of the General Land Office survey. The individual contracted for the largest area, one S. A. Hanson, was later listed among those associated with the Benson Syndicate, and he combined actual with probably fabricated surveys. Topographic surveys performed by Lieutenant Montgomery M. Macomb, under George M Wheeler's Surveys West of the 100th Meridian, were completed in the late 1870s and early 1880s.
Mariposa Wars
James Savage's trading camp on the Merced River, west of Yosemite Valley, was raided by Native Americans in December 1850, after which the raiders retreated into the mountains. The camp had been founded because the California Gold Rush had begun in 1849 bringing more than 40,000 gold seekers down the California Trail into northern and central California. This rapid influx of non-native settlers precipitated the California genocide of the indigenous peoples in the State. Before 1849, much of Northern and Central California had been populated by Native Americans and Californios (the descendants of early Spanish settlers). However by 1873, almost 80 percent of California's Native American population had been wiped out by conflict and disease, and their historic land seized by settlers from Mexico, South America, Europe, Australia, and China.
In response to miners forcing Native Americans off their historic lands in search for gold, Native Americans launched punitive raids against camps and settlements. Some tribes were pressed into service in mines; others had their villages raided by the army and volunteer militias. Some white settlers also thought it was time to get rid of Native Americans because they commanded too much labor in the mines. In retaliation for the attack on his camp, a month later in January 1851, Jim Savage led a militia in a punitive action against a native village, but after opening fire they were beaten back by indigenous firepower. Savage appealed to John McDougal, governor of California to raise a formation to sort the "Indian problem" out once and for all. The subsequent campaigns led by the Mariposa Battalion in 1851 became known as the Mariposa War.
Savage led the battalion into Yosemite Valley in 1851, in pursuit of around 200 Ahwaneechees led by Chief Tenaya. On March 27, 1851, the company of 50 to 60 men reached what is now called Old Inspiration Point, from where Yosemite Valley's main features are visible. Chief Tenaya and his band were eventually captured and their village burned, fulfilling the prophecy an old and dying medicine man had given Tenaya many years before. The Ahwahnechee were marched from their tribal lands under armed guards led by Captain John Bowling, to the Fresno River Reservation. With the fighting ended, the battalion was disbanded on July 1, 1851.
Life on the reservation was unpleasant and the Ahwahneechee longed to return to the Yosemite area. Reservation officials consented and allowed Tenaya and some of his band to return to their lands. However, in May 1852 a group of eight armed miners entered Yosemite Valley and were allegedly attacked by Tenaya's warriors; two of the miners were killed. In retaliation regular army troops under the direction of Lt. Tredwell Moore shot dead six Ahwahneechee who were in possession of European clothing.
Tenaya's band fled the valley and sought refuge with the Mono people, his mother's tribe. A year later, in mid-1853, the Ahwahneechee returned to the valley but they betrayed the hospitality of their former Mono hosts by stealing horses that the Mono had taken from non-indigenous ranchers. In return, the Monos tracked down and killed many of the remaining Ahwahneechee, including Tenaya (Tenaya Lake is named after the fallen chief). Inter-tribal hostilities eventually subsided and by the mid-1850s local European American residents started to befriend Native Americans still living in the Yosemite area.
