Lake Mountain, Utah - 7.5 Minute Series Topo Map Historical Geology To further quantify the GunlockThe distinctive characteristic of a topographic map is that the shape of the Earth's surface is shown by contour lines.

Contours make it possible to measure the height of mountains, depths of the ocean bottom, and steepness of slopes. A topographic map shows more than contours. The map also includes
