Notes on a coal deposit on the Beluga River, Alaska
Farrell F. Barnes
1955, Open-File Report 55-5
This report is based on a brief examination of a locality on the Beluga River, about 50 miles west of Anchorage, Alaska (fig. 1), that had been reported to contain a coal bed of exceptional thickness and quality, possibly suitable for large-scale strip mining. I visited the locality on August...
Preliminary geologic map and structure sections along a part of the lower Yukon River, Alaska

Photogeologic procedures in geologic interpretation and mapping
Richard G. Ray
1955, Open-File Report 55-144
In the past few years increasing use has been made of aerial photographs for geologic interpretation and mapping within the U.S. Geological Survey. As a specialized technique in interpretation and mapping, however, photogeologic procedures were extensively used (1947-1953) in the Survey's geologic mapping of Naval Petroleum Reserve No. 4 in...
