Rock Crawler
Grylloblattidae, commonly known as the icebugs, or ice crawlers, is a family (biology), family of extremophile (psychrophile) and wingless insect, wingless insects that live in the cold on top of mountains and the edges of glaciers. They belong, along with Mantophasmatidae (rock crawlers), to the order Notoptera. Grylloblattids are wingless insects mostly less than 3 cm long, with a head resembling that of a cockroach, with long antennae and having elongated cerci arising from the tip of their abdomen. They cannot tolerate warmth (most species will die at 10 °C) and many species have small distribution ranges. Overview Grylloblattids, ice crawlers or icebugs puzzled the scientists who discovered them in 1914, E.M. Walker and T.B. Kurata; the first species named was ''Grylloblatta campodeiformis'', which means "cricket (insect), cricket-cockroach shaped like a ''Campodea''" (a kind of two-pronged bristletail). Most are nocturnal and appear to feed on detritus. They have long ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Sonora Pass
Sonora Pass (el. 9,624 ft. / 2,933 m.) is a mountain pass in the Sierra Nevada in California. It is the second-highest in California and in the Sierra Nevada. lower by 321 ft. (about 98 m.) than Tioga Pass to the south. State Route 108 traverses the pass, as does the Pacific Crest Trail. Description The pass connects the communities of Sonora to the west and Bridgeport to the east. Like Ebbetts Pass to the north and Tioga Pass to the south, the highway closes during winter, generally between November and May, due to snow accumulation. The highway over the pass is extremely steep (exceeding 8% for most of the traverse, and up to 26% grades in some locations), narrow and winding between Kennedy Meadows on the west side and Leavitt Meadows on the east. The route is not recommended for vehicles or vehicle combinations that are unusually wide, heavy or long. The Pacific Crest Trail, a 2,650 mile (4,240 km) long National Scenic Trail, crosses Highway 108 at Sonora P ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

It lies on the Great Basin Divide, with the West Fork Carson River on the east and the South Fork American River on the west. The historic pass was a point on the Carson Trail during the California Gold Rush and was used for American Civil War shipping to California until the completion of the First transcontinental railroad.

Sierra Nevada (U
The Sierra Nevada () is a mountain range in the Western United States, between the Central Valley of California and the Great Basin. The vast majority of the range lies in the state of California, although the Carson Range spur lies primarily in Nevada. The Sierra Nevada is part of the American Cordillera, an almost continuous chain of mountain ranges that forms the western "backbone" of the Americas. The Sierra runs north-south and its width ranges from to across east–west. Notable features include General Sherman, the largest tree in the world by volume; Lake Tahoe, the largest alpine lake in North America; Mount Whitney at , the highest point in the contiguous United States; and Yosemite Valley sculpted by glaciers from one-hundred-million-year-old granite, containing high waterfalls. The Sierra is home to three national parks, twenty wilderness areas, and two national monuments. These areas include Yosemite, Sequoia, and Kings Canyon National Parks; and ...
