Kodiak and Vicinity Alaska
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-bearing lodes have been staked, and a few unsuccessful attempts at lode mining have been made.

Kodiak and Adjacent Islands, Alaska
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.

Bentonite Deposits of the Northern Black Hills District Wyoming, Montana, and South Dakota
From abstract: The northern Black Hills bentonite mining district includes parts of Crook County, Wyo., Carter County, Mont., and Butte County, S. Dak. Within this district, many beds of bentonite occur interspersed with sedimentary strata of Cretaceous age that have an average total thickness of about 3,000 feet and consist chiefly of marine shale, marl, and argillaceous sandstone. The bentonite beds occur in formations ranging upward from the Newcastle sandstone to the lower part of the Mitten black shale member of the Pierre shale. Tertiary (?) and Quaternary deposits of gravel, sand, and silt are present on extensive terraces, and deposits of such materials also extend along stream courses in all parts of the district.
