Abstract
During the summer of 1946 the United States Geological Survey, as part of its program of stratigraphic and structural investigations in the Naval Petroleum Reserve No. 4, had one field party investigating the Umiat area.
The stratigraphy of the area was already fairly well known from earlier investigations. The main object of this investigation was to delineate, in as much detail as possible, the Umiat anticline in the are of Umiat Test No. 1.
Outcrops in the Umiat area are few. Direct compass readings for strikes and dips of bedding cannot be trusted since cross-bedding. slumping, and frost-heaving are the rule rather than the exception. `structural data was obtained by use of a plane table and alidade by the three-point method. On the accompanying geologic map many of the strikes and dips shown were obtained by solving three-point problems. Additional structural data was obtained by mapping structural traces.*
