Book excerpt: Excerpt from Pennsylvania Glaciation First Phase: Materials for a Discussion of the Attenuated Border of the Moraine Described in Volume Z of the Second, Geological Survey of Pennsylvania A revision of previous work on the Attenuated Border became imperative when it was found that "drift" could consist of pieces neither rolled, glaciated nor moved from an outcrop, but merely disturbed by the advance of the First Phase of the glacier, which brought nothing foreign. The glacial strife are associated with the regional troughs along which this Phase moved towards and upon Pennsylvania in the form of low and weak lobes, and over which the greatest motion obtained during the Mature Phase. The outcrops crossed furnished a check-list of probable rocks in the drift. The drainage lines marked where each lobe lost some of its basal burden. The origin of the stony gravel was solved. These criteria agreed with President T. C. Chamberlin's assumption of a Labrador glacier moving to Illinois. Native copper and crystalline rocks are found only in the extreme, eastern and western parts of Pennsylvania in the drift of this Phase. In both localities floating ice seems to have played an important part. With no intention of claiming a Lake Superior origin for the Connecticut and Eastern Pennsylvania copper, the latter can not come from the Trias entirely, as it is found in Monroe County, north of Kittatinny Mountain. Western Pennsylvania copper certainly has a Keewatin origin, and the specimen was berg-carried. As the surface of Mohawk Valley is everywhere below 500 feet above ocean level, and as Central New York was flooded far above that elevation, ice-cakes could have floated into the Hudson without insisting upon an extension of Professor Spencer's Erigan trough thither, and the assumption of his rock-floor levels north of Potter County, Penna., has no bearing on a Hudson outlet. The mining engineer will find something of interest in the "mucking" of 60 feet of slate outcrop, by which the merchantable product is quarried beneath loose drift. The mining of anthracite with the highest of carbon ratios from beneath glacial gravel is interesting as showing that an exposure of many thousand years has no appreciable effect on this coal.

Available in PDF, EPUB and Kindle. Book excerpt: This investigation was conducted as the first part of a program to study the glacial geology of northwestern Pennsylvania ... Field work and laboratory investigations have been conducted with the aim to determine the stratigraphic relationships and the specific character of the various tills in the area. Mapping of kames, valley trains and such features was included to give a complete picture of the surficial geology. For this reason most attention is given to the character, distribution, and age relations of the tills.
