Book Description
Excerpt from Existing Glaciers of the United States The formation of glaciers in any region depends primarily on the fact that the amount of snow precipitated during a term of years exceeds the amount dissipated by melting and evaporation. In this manner snow bank of broad extent are formed, the lower portions of which become compacted into ice. The change from snow to ice is known to result from pressure, and as ice is mobile under pressure, either by reason of its inherent plasticity or as a result of regelation, the weight of this mass tends to change its form, and it thus acquires motion, which takes the direction of least resistance. The essential characteristic of glaciers seems to be that they result from the consolidation of snow in regions of secular accumulation, i. Above the snow-line, and ow to regions of dissipation, i. Below the snow-line. From these primary conditions result a multitude of second ary phenomena. For convenience of reference we will divide glaciers into alpine and continental; not that the two classes are alway distinct and separable, but for the reason that typical examples of each are well characterized and capable of specific description. Variations occur in each class which may suggest minor subdivisions. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.

Book Description
Excerpt from Lake Agassiz: A Chapter in Glacial Geology The superficial material which'overlies the bed-rock with 111 this northern glaciated area has everywhere beeh ploughed up and worked over by the slowly moving ice-sheet, and at its disappearance was left in a deposit of, clay, sand, gravel and boulders, mixed in one confused mass, which 18 called till. Except in the valleys, as 'of the Mississippi at Minneapolis, where streams have assorted the'se materials and spread them in layers, the till forms the surface of nearly all of Minne sota, its thickness being from 50 to 250 feet. It is the Stony and gravelly clay, in which cellars and wells are dug; and it forms a sheet of such great extent and. Thickness that about half of the counties of western Minnesota contain no exposures of the underlying older rocks.

Book Description
Excerpt from Glaciers of Glacier National Park From Gunsight Camp, an easy trail leads southward about 1 mile, with an ascent of about 500 feet, to the foot of the main lobe of the western part of the glacier. Climbing the morainal embankment which obstructs the view one looks out on a scene Of surpassing interest and grandeur. The distance across the glacier on a nearly east - west line, is miles; the maximum extent southward from the front of the eastern lobe to the crest of the snow-covered Continental Divide on Blackfoot Mountain is miles; the distance from the front of the western lobe to the divide southeast of Jackson Mountain is nearly the same; the approximate area Of the entire mass is 3 square miles. Lying in a depression in the mountain slope, having a greater extent laterally than in the direction of movement, and having no lobate extension down the valley, it is what is known as a cliff glacier.
