Abstract: A sample of carnotite, thought to have been found in the Alaska Railroad belt, was assayed at the Fairbanks Assay Office in 1918, but the exact location from which the material had come was never determined. A "uranium" prospect, apparently unrelated to the carnotite occurrence, was recently staked 4 miles south of Healy. A radiometric traverse along the railroad was undertaken in 1950 in an effort to locate any possible deposits of radioactive material in the vicinity of the right-of-way: None were found.

From introduction: Since 1945 the Alaskan Trace Elements Unit of the U. S. Geological. Survey has been engaged in reconnaissance for radioactive deposits in Alaska, first on behalf of the Manhattan Engineer District, later on behalf of the Atomic Energy Commission. During the period January 1945 through December 1952, 42 reports in the Survey's Trace Elements Investigations series and 18 reports in the Trace Elements Memorandum series, a totaJ of 60 reports, have been completed or are in preparation Of these 60 reports 44 have been completed and transmitted to the Commission as of December 31, 1952.

From abstract: Two deposits of high-grade gypsum are located near tidewater at Iyoukeen Cove, on the northeastern part of Chichagof Island, southeastern Alaska. A group of claims, formerly operated by the Pacific Coast Gypsum Co., was acquired by the Kaiser Gypsum Division of Kaiser Industries, Inc., during World War II. Claims at the other deposit are held by Dave Housel of Juneau and Seattle, Washington, in the name of the Gypsum-Camel group.

From Forward: "This bulletin is the first of a new series, which includes analyses of only tipple and delivered coal. It covers samples collected throughout the United States from July 1, 1947 to June 30, 1950 (fiscal years 1948-50). It is planned that future publications of this series will cover a period of one fiscal year only and be issued as soon as possible after June 30 of each year."
