Photogeologic map, Notom 15 quadrangle, Garfield County, Utah

Aerial photographs in geologic interpretation and mapping

“…In photogeologic interpretation and mapping of the Notom-15 quadrangle, Utah, (Hackman and Tolbert, 1955) altitudes for structure contouring were measured using a Kelsh plotter. No previous geologic or topographic mapping had been done in the area; geologic data and altitude measurements were plotted to a control net established by photogrammetric methods.…”
