what purpose does the ridge serve( topographical map)?
Answers
A ridge is a landform feature characterized by a continuous elevational crest with sloping sides. Arête is a narrow ridge formed by glacial erosion. A spur is a lateral ridge projecting from the mountain or the main ridge crest. A spur is usually formed by the two roughly parallel streams eroding gullies (draws) down the face of the mountain from the ridgeline. (check out interlocking spurs and truncated spurs for more information). Ridges are represented by "U" or "V" shaped contour lines with their closed end pointing towards lower elevation. U-shaped contours indicate broader ridges, while V-shaped contours represent narrower and sharper ridgelines. Aretes and spurs are often generally referred to as ridges in backcountry recreation.
