Core Drilling for Coal in the Moose Creek Area, Alaska

Description: From abstract: The Moose Creek area is in the western part of the Matanuska Valley, in south-central Alaska, about 165 miles by railroad north of the coast at Seward. Coal deposits in the valley have been known since the early 1890's, and there have been producing mines since 1916, but the annual production is only about 40,000 tons, or less than one-third of the total amount consumed in the Territory. Early in 1931 Congress authorized the investigation of mineral resources in areas tributary t… more

The Curry District, Alaska

Description: From abstract: The Curry district lies on the south flank of the Alaska Range, on the southeast side of Mount McKinley. Most of it is west of the Alaska Railroad. The eastern portion can be easily reached from several points along the railroad route, but the western portion is much more difficult of access, owing to the numerous glacial streams and the rugged topography. The relief of the area is great, the elevation ranging from 500 feet along the Chulitna River to 20,300 feet at Mount McKinle… more

Geology and Ore Deposits in the Reid Inlet Area Glacier Bay, Alaska

Description: From abstract: A gold-bearing area of about 7% square miles near the head of Glacier Bay between Reid and Lamplugh Glaciers was first discovered by Mr. Joseph Ibach in 1924. The dominant rock type in the area is granodiorite, which is intruded into bedded rocks that may be of Paleozoic age. The bedded rocks consist of conglomerate, limestone, and black graphitic schist. A light-colored quartz diorite younger than the granodiorite crops out south of the mapped area.

Geology of the Prince William Sound Region, Alaska

Description: From introduction: This paper describes the geology of the Prince William Sound region, a part of south-central Alaska. It deals with the rocks of a section of the Coast Ranges that has been studied by various geologists over a period of many years and still offers basic problems that are unsolved. Prince William Sound is well known for its mining activities, but the intention here is to describe the areal and stratigraphic geology of the district rather than its mineral resources and to presen… more

Kodiak and Adjacent Islands, Alaska

Description: From abstract: The Kodiak group of islands, having an area of 4,900 square miles, lie on the Pacific Ocean side of the base of the Alaska Peninsula. Although the town of Kodiak is the oldest continuously occupied white settlement in Alaska, the interior of many of the islands is still little explored and unmapped, for the heavy growth of vegetation makes inland travel difficult, and few trails penetrate far from the coast.

Kodiak and Vicinity Alaska

Description: From abstract: Kodiak Island, although the site of the earliest white settlement in Alaska and the center of a vigorous fishing industry, is still largely unexplored, except for a strip immediately adjacent to the shores. The heavy growth of vegetation makes access to the interior of the island difficult, and few trails penetrate far from the coast. Mining activity in the past has been confined to somewhat desultory exploitation of beach sands, which in places carry gold, though some gold-beari… more
