Past Placer-Gold Production from Alaska

Description: "To the end of 1930 Alaska, according to the records of the Geological Survey, had produced placer gold to the value of $258,962,000 from mines widely scattered throughout its length and breadth. The distribution of the placers from which the gold was recovered has been stated in more or less detail in the annual summaries published by the Geological Survey on the mineral industry of Alaska and also in its more complete reports on many of the individual mining districts. Although these summaries and reports have furnished information regarding the larger regions, they have not always given specific details regarding the smaller districts. Furthermore, there has been no recent attempt to assemble and publish in one place the scattered statistics regarding the placer-gold production by years and by regions and districts. The purpose of the present report is to set forth in condensed but comprehensive form a summary of the placer-gold production of Alaska so far as it can be determined from the available official records."

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 McKinley. The Chulitna River, a tributary of the Susitna River, drains the larger part of the area described. It flows in a broad valley in the eastern part of the district, and here the maximum relief is about 3,000 feet. The western part of the district is very rugged, with numerous peaks over 6,000 feet in elevation which have sheer slopes and almost unscalable pinnacles. Winding down through this maze of rugged mountains are four major valley glaciers-Eldridge, Buckskin, Ruth, and Tokichitna-and many tributary and smaller glaciers. Practically the entire district, with the exception of the higher peaks and ridges, has been glaciated. Timber grows along the main streams and extends to an elevation of 2,000 feet, but a large portion of the district lies above that elevation.

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 to the Alaska Railroad, which is Government owned and operated, for the purpose of stimulating development and hence increasing the traffic and revenue of the railroad. The technical work of carrying on these studies was entrusted by Col. O. F. Ohlson, general manager of the railroad, to the United States Geological Survey. One of the investigations undertaken was that of the Moose Creek area, where small coal mines are in operation. Difficulties have been encountered in these mines, owing to the faulted character of the formation, which causes unproductive work in mining and also produces a large percentage of fine coal, which is unsuitable for sale in distant markets. Field examination indicated that more favorable mining conditions might be found somewhat farther west. Core drilling was therefore done in 1932, in order to learn if workable beds of coal were present that might he mined at less cost and produce a better product than the present mines for competitive sale in markets of the Pacific coast.

Notes on the Geology of the Alaska Peninsula and the Aleutian Islands

Description: Abstract: During the spring of 1932 an opportunity was offered by the United States Navy for a geologist to accompany an expedition organized to make a reconnaissance of the western part of Alaska Peninsula and the Aleutian Islands. This expedition visited several localities the geology of which was little known. It was found, as had already been expected, that the islands west of Unimak Pass are composed mainly of basic volcanic lavas and fragmental materials, into which have later been injected dikes, sills, and considerable masses of intrusive rocks, some of which are of acidic types and of granitic texture. These westward islands are bordered both to the north and south by depressions 2,000 fathoms or more in depth, and the islands have apparently been built up from that depth by the ejection and extrusion of volcanic materials since early Tertiary time. No rocks of proved pre-Tertiary age were seen, and the only sedimentary materials present may well have been derived from the erosion of the volcanic islands after they were built up above sea level. On the Alaska Peninsula pre-Tertiary sediments through which the volcanic materials broke to the surface are abundantly present. There is evidence that all the larger islands and the higher portions of the peninsula were severely glaciated during Pleistocene time. Each of the larger islands was the center of ice accumulation and dispersal, and the present topography, except upon recently active volcanic cones, shows strongly the effects of glacial sculpture.

Radioactivity Investigations at Ear Mountain, Seward Peninsula, Alaska, 1945

Description: From abstract: Radioactive material in apparently significant amounts was recognized in heavy-mineral concentrates from the gravels of four streams that head in Ear Mountain, Alaska, when collections of the United States Geological Survey were examined for radioactivity in the winter of 1944-45. This area, on the north side of the Seward Peninsula, attracted attention in 1901-02 when cassiterite was discovered in the streams. Subsequent attempts were made to develop copper- and tin-bearing lode deposits.

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.

Reconnaissance for Radioactive Deposits in Southeastern Alaska, 1952

Description: From abstract: Reconnaissance for radioactive deposits in southeastern Alaska in 1952 was centered in three localities: the northern part of Prince of Wales Island and parts of adjacent islands, the Taku Harbor-Point Astley district, and the Hyder area. Significant concentrations of radioactive minerals were found only in the vicinity of Salmon Bay on the northeastern shore of Prince of Wales Island. In this area radioactive carbonate-hematite veins occur along the coast for about 8 miles. The veins are generally short, irregular, and lenticular, but a few can be traced for more than 300 feet between the low-tide line and the forest cover. The width of the veins normally ranges from less than 1 inch to 2.5 feet; several, however, are 5 to 10 feet wide.

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

Mineral industry of Alaska in 1934

Description: From Introduction: "The value of its mineral resources has long been recognized as a matter of concern in the welfare of every nation, and all wise governments almost from time immemorial have taken steps to find out about, utilize, and safeguard such of these natural resources as lie within their own boundaries or to acquire rights in those they need that lie outside those boundaries. Obviously one of these lines concerns itself with the record of present performance-how much of the different mineral commodities is the country at present producing, where does this production come from and what are the facts as to the current developments in the industry? To answer some of these questions authoritatively is part of the work of the Alaskan branch of the Geological Survey, and answers to those questions for the year 1934 are given in the accompanying report."
