Moro Rock is a granite dome rock formation in Sequoia National Park, California, United States. It is located in the center of the park, at the head of Moro Creek, between Giant Forest and Crescent Meadow. A stairway, designed by the National Park Service and built in 1931, is cut into and poured onto the rock, so that visitors can hike to the top. The view from the rock encompasses much of the Park, including the Great Western Divide. Use of this trail is discouraged during thunderstorms and when it is snowing.
The name "Moro Rock" derives from a blue roan mustang of color the Mexicans call moro, owned by one Mr. Swanson of Three Rivers in the 1860s. [3]
The road to Moro Rock is closed in winter, so visitors need to hike 2 miles to reach the viewpoint. The road is open in summer so the hike is shortened. The 1996 general plan for the park calls for the road to Moro to be closed, and replaced by a shuttle. As of June 2012, the road is open to general traffic only during weekdays; on weekends, the shuttle is running and the road is closed to general traffic. [4] The west face of Moro Rock offers 1,000 vertical feet of cracks and knobs for rock climbing. However, climbing is prohibited during peregrine falcon nesting season on the South and East faces (up to Full Metal Jacket). [5]
Moro Rock is a dome-shaped granite monolith. Common in the Sierra Nevada, these domes form by exfoliation, the spalling or casting off in scales, plates, or sheets of rock layers on otherwise unjointed granite. Outward expansion of the granite results in exfoliations. Expansion results from load relief; when the overburden that once capped the granite has eroded away, the source of compression is removed and the granite slowly expands. Fractures that form during exfoliation tend to cut corners. This ultimately results in rounded dome-like forms. [6]

The first stairway leading to the summit of Moro Rock was constructed of wood and installed in 1917. This stairway deteriorated significantly by the late 1920s, and was replaced in 1931 by the present Moro Rock Stairway, built by the Civilian Conservation Corps. [8] Unlike the earlier stairway, the new stairway adopted a design policy of blending with the natural surfaces to the greatest extent possible. The 797-foot-long stairway was designed by National Park Service landscape architect Merel S. Sager and engineer John Diehl, following natural ledges and crevices. It has 400 steps that lead to the summit of Moro Rock. [9] Changes since the original construction have impaired the integrity of the design. [10]
Yosemite National Park is an American national park in the state of California, surrounded on the southeast by Sierra National Forest and on the northwest by Stanislaus National Forest. The park is managed by the National Park Service and covers an area of 759,620 acres in four counties – centered in Tuolumne and Mariposa, extending north and east to Mono and south to Madera County. Designated a World Heritage Site in 1984, Yosemite is internationally recognized for its cliffs, waterfalls, clear streams, giant sequoia groves, lakes, mountains, meadows, glaciers, and biological diversity. Almost 95 percent of the park is designated wilderness. Yosemite is one of the largest and least fragmented habitat blocks in the Sierra Nevada, and the park supports a diversity of plants and animals.
The John Muir Trail (JMT) is a long-distance trail in the Sierra Nevada mountain range of California, passing through Yosemite, Kings Canyon and Sequoia National Parks. From the northern terminus at Happy Isles in Yosemite Valley and the southern terminus located on the summit of Mount Whitney, the trail's length is 213.7 miles (343.9 km), with a total elevation gain of approximately 47,000 feet (14,000 m). For almost all of its length, the trail is in the High Sierra backcountry and wilderness areas. For about 160 miles (260 km), the trail follows the same footpath as the longer Pacific Crest Trail. It is named after John Muir, a naturalist.
Tuolumne Meadows is a gentle, dome-studded, sub-alpine meadow area along the Tuolumne River in the eastern section of Yosemite National Park in the United States. Its approximate location is 37°52.5′N119°21′W. Its approximate elevation is 8,619 feet (2,627 m). The term Tuolumne Meadows is also often used to describe a large portion of the Yosemite high country around the meadows, especially in context of rock climbing.
Kings Canyon National Park is an American national park in the southern Sierra Nevada, in Fresno and Tulare Counties, California. Originally established in 1890 as General Grant National Park, the park was greatly expanded and renamed to Kings Canyon National Park on March 4, 1940. The park's namesake, Kings Canyon, is a rugged glacier-carved valley more than a mile (1,600 m) deep. Other natural features include multiple 14,000-foot (4,300 m) peaks, high mountain meadows, swift-flowing rivers, and some of the world's largest stands of giant sequoia trees. Kings Canyon is north of and contiguous with Sequoia National Park, and both parks are jointly administered by the National Park Service as the Sequoia and Kings Canyon National Parks.
Sequoia National Park is an American national park in the southern Sierra Nevada east of Visalia, California. The park was established on September 25, 1890, and today protects 404,064 acres of forested mountainous terrain. Encompassing a vertical relief of nearly 13,000 feet (4,000 m), the park contains the highest point in the contiguous United States, Mount Whitney, at 14,505 feet (4,421 m) above sea level. The park is south of, and contiguous with, Kings Canyon National Park; both parks are administered by the National Park Service together as the Sequoia and Kings Canyon National Parks. UNESCO designated the areas as Sequoia-Kings Canyon Biosphere Reserve in 1976.
Lembert Dome is a granite dome rock formation in Yosemite National Park in the US state of California. The dome soars 800 feet (240 m) above Tuolumne Meadows and the Tuolumne River and can be hiked starting at the Tioga Road in the heart of Tuolumne Meadows, 8 miles (13 km) west of the Tioga Pass Entrance to Yosemite National Park. The landform is an example of a rôche moutonnée with clear lee and stoss slopes.
The High Sierra Trail (HST) is a hiking trail in Sequoia National Park, California. The trail crosses the Sierra Nevada from west to east. According to the Yosemite Decimal System, the HST is a Class 1/Class 2 trail, which means simple scrambling, with the possibility of occasional use of the hands for balance.
Mount Langley is a mountain located on the crest of the Sierra Nevada, on the boundary between Inyo and Tulare counties in eastern California, in the United States. To the east is the Owens Valley, and to the west is the Kern River Valley. It is the ninth-highest peak in the state and the seventh-highest in the Sierra. Mount Whitney, the highest peak in the contiguous United States, lies 4.8 miles (7.7 km) to the northwest. Mount Langley also has the distinction of being the southernmost fourteener in the United States.
The Giant Forest, famed for its giant sequoia trees, is within the United States' Sequoia National Park. This montane forest, situated at over 6,000 ft (1,800 m) above mean sea level in the western Sierra Nevada of California, covers an area of 1,880 acres (7.6 km2). The Giant Forest is the most accessible of all giant sequoia groves, as it has over 40 mi (64 km) of hiking trails.

Yosemite National Park is located in the central Sierra Nevada of California. Three wilderness areas are adjacent to Yosemite: the Ansel Adams Wilderness to the southeast, the Hoover Wilderness to the northeast, and the Emigrant Wilderness to the north.
The High Sierra Camps are nine rustic lodging facilities located in two national parks and a national monument in California's Sierra Nevada mountain range. Open most years from June or July to September, they are staffed camps with tent cabins and food service facilities. The backcountry camps receive their supplies by pack mules.
Polly Dome is a prominent granite dome rising 1,640 feet (500 m) above the northwest side of Tenaya Lake and Tioga Road in the Yosemite high country. The dome, more than 3 kilometers long, is a substantially intact mass of granitic rock that has withstood heavy glaciation and exfoliation. Forest clings to the less-steep parts of its north and west slopes. The southwest end of Polly Dome consists of the Stately Pleasure Dome, 740 feet (230 m) lower than Polly Dome, but rising very steeply 900 feet (270 m) from the shore of the lake. Polly Dome's summit has unobstructed views east to the Cathedral Range, north over Tuolumne Meadows to the Sierra crest, northwest over the Grand Canyon of the Tuolumne and southwest to Half Dome.
