Schneider Peak
Schneider Peak () is a peak rising to about 1,300 m near the head of Rankin Glacier, 6 nautical miles (11 km) west-southwest of Mount Geier, Schirmacher Massif, on the Black Coast of Palmer Land. The peak was mapped by United States Geological Survey (USGS) from U.S. Navy aerial photographs, 1966–69, and was visited by a joint USGS-BAS geological party, 1986–87. Named by Advisory Committee on Antarctic Names (US-ACAN) in 1988 after David L. Schneider, cartographer, USGS, a member of the USGS satellite surveying team at Australia's Casey Station, winter party 1974. While assigned to the Law Dome ice-drilling team during March 1974, Schneider voluntarily rescued three Australian co-workers whose Nodwell snow traverse vehicle had fallen into a deep crevasse A crevasse is a deep crack, that forms in a glacier or ice sheet that can be a few inches across to over 40 feet. Crevasses form as a result of the movement and resulting stress associated with the shear stress generat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Summit (topography)
A summit is a point on a surface that is higher in elevation than all points immediately adjacent to it. The topographic terms acme, apex, peak (mountain peak), and zenith are synonymous. The term (mountain top) is generally used only for a mountain peak that is located at some distance from the nearest point of higher elevation. For example, a big, massive rock next to the main summit of a mountain is not considered a summit. Summits near a higher peak, with some prominence or isolation, but not reaching a certain cutoff value for the quantities, are often considered ''subsummits'' (or ''subpeaks'') of the higher peak, and are considered part of the same mountain. A pyramidal peak is an exaggerated form produced by ice erosion of a mountain top. Summit may also refer to the highest point along a line, trail, or route. The highest summit in the world is Mount Everest with a height of above sea level. The first official ascent was made by Tenzing Norgay and Sir Edmund Hillary ...
