Photogeologic map of the Mount Peale 13 quadrangle, San Juan County, Utah

Incomplete manuscript on stratigraphy and structural geology and uranium-vanadium and copper deposits of the Lisbon Valley area, Utah-Colorado

“…This unpublished map was incorporated in regional maps compiled by Fischer (1944) and by Andrews and Hunt, C.B., (1948). Photogeologic maps of most of the Lisbon Valley area and the adjoining La Sal, Utah-Colorado area were open-filed in 1952-53 and in part published in 1956-57 (Hackman, 1952(Hackman, , 1956aHackman and Tolbert, 1956;Tolbert, 1952Tolbert, , 1957a. The bedrock geology of the La Sal Mountains was studied by Hunt, C. B., (1958); the surficial deposits, by Richmond (1962).…”

“…3). The structure in figure 20 is based upon the depth to the top of the salt in Lisbon Dome 1 of the Union Oil Co. of California, the surface dips and outcrop widths from photogeologic maps of the U.S. Geological Survey (Hackman, 1952(Hackman, , 1956Hackman and Tolbert, 1956;Tolbert, 1952Tolbert, , 1957, and the assumed thicknesses of beds younger than the Paradox evaporites on the flanks of the structure, as shown. The trend of the contour lines in figure 19 parallels the trend of the contour lines on top of the Cutler formation (Lekas and Dalil, op.…”
