Large springs in the United States

What are the largest springs in the United States, how much water do they discharge, and what geologic conditions produce them are questions of much popular interest and considerable scientific and economic importance. Yet the information in regard to large springs has been so widely scattered and so difficult to interpret that most people have only very vague notions on the subject. The present p

Manganese-bearing deposits near Lake Crescent and Humptulips, Washington

The Crescent mine, situated a short distance west of Lake Crescent, in the Olympic Mountains of Washington, yields an unusually high grade of manganese ore, which is suitable for making steel. Several manganiferous lodes of promising appearance have been found in the same area, and some near Humptulips, on the south side of the mountains. These and deposits on Skokomish River and at other places i

Organic precipitation of metallic copper: Chapter C in Contributions to economic geology (short papers and preliminary reports), 1927: Part I - Metals and nonmetals except fuels

Spongy masses of native copper, found in a bog near Cooke, Mont., are believed to have been precipitated by organic matter. Their occurrence and field relations are such as sharply limit speculations concerning their origin.

Phosphate rock in the Three Forks-Yellowstone Park region, Montana: Chapter G in Contributions to economic geology (short papers and preliminary reports), 1927: Part I - Metals and nonmetals except fuels

The region described is about 7,000 square miles in area. It includes most of Gallatin and Madison Counties, in Montana, and some contiguous parts of Idaho and Wyoming. Within it are several broad fertile valleys and a number of prominent mountain ranges. A considerable part is underlain by a bed of phosphate rock which occurs in the Phosphoria formation, of Permian age, and is elevated to the sur

Plants as indicators of ground water

Perhaps the most outstanding feature of the flora of the desert is its relation or lack of relation to the water table. On the one hand are the plants which are adapted to extreme economy of water, which depend on the rains that occur at long intervals for their scanty water supplies, and which during prolonged periods of drought maintain themselves in a nearly dormant condition. These plants are

Potash brines in the Great Salt Lake Desert, Utah: Chapter B in Contributions to economic geology (short papers and preliminary reports), 1927: Part I - Metals and nonmetals except fuels

During and immediately after the war the brines of the Salduro Marsh, in the Great Salt Lake Desert, were a source of considerable potash for the domestic supply. Although no potash has been produced from these brines in the last few years, a continued interest in the area has been shown by a large number of filings, in different parts of the desert, under the potash law of October 2, 1917 (40 Sta
