while the rhyolitic Sapphire Mountain lava flow is Miocene

Stratigraphic constraints on the time of the paleoearthquake WC4 are extremely poor

A topographic map shows more than contours

Salt Lake City's Trails is David Day's most recent work

It reflects the current understanding of the geology of the eastern Uinta Mountains built upon past generations of geologists

Burnt Strip Mtn, Idaho - 7.5 Minute Series Topo Map economic geology while the rhyolitic Sapphire MountainThe 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
