Lisbon Valley, Utah - 7.5 Minute Series Topo Map Shelf 17 Pre-Pleistocene Tertiary freshwater ostracode assemblagesThe distinctive characteristic of a topographic map is that the shape of the Earth's surface is shown by contour lines. Contours are imaginary lines that join points of equal elevation on the surface of the land above or below a reference surface, such as mean sea level. 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
