It is characterized by a sequence of long, deep valleys - the basins - and running parallel between them high mountain crests - the ranges.
Relief production at high-elevation mountain crests is addressed using a numerical model that incorporates glacier dynamics and subglacial erosion, as well as relevant hillslope processes.
The highest mountains top 14,000ft.
Most of Kyrgyzstan's borders run along mountain crests.
That is why giant failures of mountain crests have mainly occurred in areas of tectonic activity.
In Biblical days vast stretches of mountainsides and mountain crests, now nearly de nuded, were covered with trees.
According to text sources, Inanna's home was on Kur-mùsh, the mountain crests.
During the last ice age, some 11,500 years ago, glaciers carved the mountain crest lines and high valleys from rounded, convex terrain into sharp, rugged, concave topography and, when they melted, left the loose earth material that they had gouged out of the mountains as glacial deposits in the valley bottoms.
A simple numerical landscape evolution model is used to investigate the rate of erosional decay of the Yucca Mountain crest in Nevada, USA — a location proposed as a permanent repository for high level radioactive waste.
Nearly 7,000 feet below the mountain crest, Simplon encountered major problems from highly stressed rock flying off the walls in rock bursts; high pressure in weak schists and gypsum, requiring 10-foot-thick masonry lining to resist swelling tendencies in local areas; and from high-temperature water (130° F [54° C]), which was partly treated by spraying from cold springs.
