EXPLANATION Lake Warren was t.ho rostglaolal water held by the wasting glacier over the southern Huron basin, the Erie basin, and the Southern part of the Ontario basin, as shown in this map. Its outlet was westward across Michigan to tho glacial lake Ohi- oago and to Mississippi drainage. It invaded New York from the west, extending as a narrow bolt along the retreating front of tho ice sheet, with southward prolon- gations up the north and south valleys. When the recoding ice had uncovered ground In the Syra- cuse region lower than the west- ward outlet across Michigan the watorflowod eastward to Mohawk drainage ; and whou the westward outlet was abandoned tho water ceased to be Lake Warren The eastward flow of tho Hypo- Warren (or Hyper-Iroquois) waters cut the remarkable sories of canyons and cataract basins in the Syracuse region which aro simply indicated on this map. [Soe 20th annual report, p. 122, 128, 120-30 and pi. 15, 25-83]. Finally the waters were lowered to the Iroquois level, falling through a vertical distauco of about 440 feet. The land has since been lifted nearly 300 feot higher than it was during the life of Lake Warron and the elevation of the Warren level in the Syracuse region is today about 880 to 890 feet above ocean. The ice margin is generalized in this map and is somewhat hypothetic. The incipient stage of Lake Iro- quois is shown, but the entire lake is mapped in plate 19, 20th annual report of state geologist.
