The following report discusses the results of an evaluation of the uranium resource potential of the Seward Peninsula and Selawik area that was done in 1977.

From introduction: This report describes work done in the Noatak and portions of the Baird Mountains and Ambler River, Alaska, National Topographic Map Series (NTMS) quadrangles (1:250 000 scale) by the Los Alamos Scientific Laboratory (LASL) as part of the nationwide Hydrogeochemical and Stream Sediment Reconnaissance (HSSR).

From introduction: This report describes work done by the Los Alamos Scientific Laboratory (LASL) for the United States Department of Energy (US DOE) over a 50 000-km2 area on the Seward Peninsula and vicinity, Alaska, in 1976 (Fig. 1). The DOE Grand Junction Office (GJO), in Colorado, is responsible for administering the nationwide Hydrogeochemical and Stream Sediment Reconnaissance (HSSR) as part of its National Uranium Resource Evaluation (NURE) program.

From abstract: Several low-level radiometric anomalies had been detected in an airborne survey of the Copper River Basin. This report presents the results of field and laboratory research on the origin of the anomalies, and the low radiometric background of the Copper River Basin.

Supplementary data containing radiometric readings of several locations to accompany a report on low-level airborne radiometric anomalies in the Copper River Basin Region, Alaska.

From introduction: This report details the results of a 256-pound high explosive cratering experiment at the Chariot test site 110 miles north of the Arctic Circle.

The following report covers analytical work on sedimentary phosphate rock deposits discovered on the Arctic Slope of Alaska during the geological investigation of Naval Petroleum Reserve No. 4 between 1944 and 1953.

Report issued by the U.S. Bureau of Mines discussing the development of a naming system for Alaskan regions and districts. The structure of the naming system and a description of each district are presented. This report includes maps.

Report discussing the U.S. Geological Survey's investigation of various radioactive mineral deposits in gold-tin placer mines of Central Alaska.

A report regarding a reconnaissance done in 1948 in order to locate radioactive deposits in the Manley Hot Springs-Rampart District, in Central Alaska.

A report regarding a Trace Elements Reconnaissance of the Southern Highway Belt, in South-Central Alaska.

Abstract: Two uranium-bearing minerals, uranothorianite and thorite (?), were found in the stream gravels of the main branch of the South Fork of Quartz Creek, a tributary of the Kiwalik River. Although the bedrock source of the minerals was not located, the radioactive material was traced in slope wash well above the stream gravel. A detailed investigation of the area with more sensitive counters might reveal the source of the minerals and localities where the minerals are sufficiently concentrated to be minable.

Report discussing the U.S. Geological Survey's investigation of radioactive trace elements along the highways in Tanana and upper Copper River valleys.

The following report provides information and findings of trace elements recognized in a few placer concentrates from Sweepstakes and Rube Creeks in the Koyuk district of eastern Seward Peninsula, Alaska when old collections were scanned for radioactivity in the spring of 1945.
