Book Description
Excerpt from Man in the Ice Age at Lansing, Kansas, and Little Falls, Minnesota The coarse debris in the lower part of the tunnel contained, so far as we could observe, no 'glacial drift pebbles or'sto-nes of foreign origin, though they are frequent in the thin gla cial drift which overlies the rock surfaces near. Many of these drift 'stones and boulders are of the red Sioux quartzite, which outcrops 300 to 350 miles northward, in southwestern Minnesota, the, northwest corner of Iowa, and the southeast part of South Dakota. It occurs in this Kansan drift mostly in small fragments, but often one to two' feet in diameter, and occasionally even measuring five feet, or more, and weighing several tons., The southern boundary of the glacial drift, marking the limit of the continental ice-sheet/in its extreme extension during the Kansan stage of the Glacial period, is at\ a line passing from east to west, as mapped by Chainberlin and mcgee, about 12 or] 15 miles southpof the Kansas (com mouly called the Kaw) river, and 25 'or 30 miles south of Lan sing.'i' About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.
