This report incorporates the results of field and. laboratory studies, from June 1946 through March 1947, of the stratigraphy and. structure of the area of the Meade and Kuk Rivers and Point Barrow, Alaska. The Investigations were made by the Geological Survey as part of the Navy Department's program of petroleum exploration in northern Alaska.

Preliminary report on the stratigraphy and structure of the Titaluk and upper Ikpikpuk Rivers, Alaska

Geological Survey Party No. 4 was assigned an investigation of the Ikpikpuk and Titaluk Rivers and East Fork of the Ikpikpuk River mainly for the purpose of obtaining stratigraphic information which would be of use in determining the parts of the Upper Cretaceous sequence that underlie the areas investigated by United Geophysical Company parties 43 and 46. A total of five days were spent in geological investigations of the Titaluk River with a Cub plane equipped with pontoons. The party was composed of the geologist and Don Hulshizer, pilot of Wien Alaska Airlines. The geologist and Ronald K. Sorem, field assistant, traversed the Ikpikpuk River by boat from the junction of Maybe Creek and the Kigalik River to near the junction of the East Fork. From the northernmost point reached by boat traverse, the river was examined by plane to north of latitude 70° N., but no outcrops or rubble indicating bedrock were seen. The East Fork was also examined from the air but no outcrops or rubble were observed.

Stratigraphy and structure of the area of the Killik, Chandler, Anaktuvuk, and Colville Rivers, Alaska

This report deals with results of field and laboratory studies carried out to May 1946 by the Geological Survey, largely as part of the Navy Department's program of petroleum investigations in northern Alaska. The immediate purpose of the work has been to collect and interpret stratigraphic and structural data pertinent to drilling in the Umiat area. Field studies were made during the summers of 1944 and 1945 in the drainage areas of the Colville, Killik, Chandler, and. Anaktuvuk Rivers (fig. 1). Paleontologic and microlithologic studies, together with stratigrahica1 and structural analysis of the areas, were carried out in the petroleum laboratory in Fairbanks. This work led. to preparation of a preliminary report submitted. in December, 1945. Additional detailed studies, in the Survey laboratories and offices in Washington, D. C., have resulted in some modification of earlier conclusions and changes in illustrations. The changes are minor and have no significant bearing on drilling in the Umiat area. The present report is accompanied. by revised conies of figures 1, 2, 3 (sheet 1) and. 5. These illustrations should be substituted for the comparable figures of the preliminary report. Figures 3 (sheet 2), 4, and. 6 of the earlier report stand unchanged and should, be added to the illustrations accompanying the present report. It is believed that work to date has revealed the general geologic picture of the area and. that the sequence of Upper Cretaceous rocks is established. The section of rocks in Umiat Test No. 1 has been approximately located within the sequence. This report, and the work on which it is based was done under the supervision of George O. Gates, who has contributed. much to the study.

Quicksilver deposits in the DeCourcy Mountain area, Iditarod district, southwestern Alaska

The DeCourcy Mountain area lies a little northwest of the Yukon-Kuskokwim divide in the southern part of the Iditarod district about 32 miles airline S. 30 ° W. of the mining town of Flat (see figs. 1-A and l-B). on Otter Creek, a tributary of the Iditarod River. DeCourcy Mountain (approximately 1700 feet high), the highest point in the area, lies among rolling hills southeast of the Iditarod River, a tributary of the Innoko. River which flows into the lower Yukon. The maximum relief is about 1300 feet. Timberline is at about 1100 feet above sea level. Spruce forests cover most of the country below timberline. The hills above timberline are moss-covered.
