Preliminary report on stratigraphy and structure of the Wolf Creek anticline, Alaska

Abstract

In 1946 U. S. Geological Survey Party 2 was assigned the task of carrying out detailed structural and stratigraphic investigations in the area of Maybe Creek*. Field studies indicated the presence of a large anticlinal structure whose axis lies just south of Wolf Creek. Later structural data compiled from aerial photographic studies indicated that the anticline is a closed structure 8-9 miles long, and as much as 6 miles wide. The evidence for a closure on the east end of the structure appears very strong, but not enough evidence was obtained to prove closure on the west end. In 1947 U. S. Geological Survey Party 1 spent two weeks at Wolf Creek, mapping bedding traces on the west end of the structure with plane table and alidade, in an attempt to prove or disprove west closure on the anticline. Party 1, consisting of 3 geologists, cook, and a "weasel" mechanic, left Umiat on July 21, and returned on August 5. Two "weasels" were used for the transportation of the party and equipment, and were also used extensively in mapping the area.
