In his presidential address before the Geological Society of America, delivered December 28, 1912, Professor Fairchild introduced his subject, “The Pleistocene Geology of New York State,” by remarking that “in variety and excellence of Pleistocene phenomena New York State probably excels any other equal area of the earth’s surface.”1
This being so, it is regrettable that the large area occupied by the Adirondacks should still be inadequately shown on our maps of Pleistocene geology. In the central area of this region, especially the Mount Marcy, the Lake Placid, the Ausable, and the Elizabethtown quadrangles, have not yet received the attention they deserve; for while the mapping of the rocks has, apparently, been done with considerable thoroughness, the glacial geology has been generally overlooked, although in the accessible valleys it is so clearly discernible that “he who runs may read.”
It has fallen to the writer to attack the problems . . .
