The Quaternary Geologic Map of the Lake Erie 4� x 6� Quadranglewas mapped as part of the Quaternary Geologic Atlas of the United States.The atlas was begun as an effort to depict the areal distribution ofsurficial geologic deposits and other materials that accumulated orformed during the past 2+ million years, the period that includes allactivities of the human species. These materials are at the surface ofthe earth. They make up the "ground" on which we walk, the "dirt" inwhich we dig foundations, and the "soil" in which we grow crops. Mostof our human activity is related in one way or another to these surfacematerials that are referred to collectively by many geologists asregolith, the mantle of fragmental and...

The surficial geologic map of the Eastern and Central United Statesdepicts the areal distribution of surficial geologic deposits and othermaterials that accumulated or formed during the past 2+ million years,the period that includes all activities of the human species. Thesematerials are at the surface of the earth. They make up the "ground"on which we walk, the "dirt" in which we dig foundations, and the �soil�in which we grow crops. Most of our human activity is related in oneway or another to these surface materials that are referred tocollectively by many geologists as regolith, the mantle of fragmentaland generally unconsolidated material that overlies the bedrockfoundation of the continent. The map is based...

This data set contains surficial geologic units in the Eastern and CentralUnited States, as well as a glacial limit line showing the position ofmaximum glacial advance during various geologic time periods. Thegeologic units represent surficial deposits and other surface materialsthat accumulated or formed during the past 2+ million years, such assoils, alluvium, and glacial deposits. These surface materials arereferred to collectively by many geologists as regolith, the mantle offragmented and generally unconsolidated material that overlies the bedrockfoundation of a continent.This data set and the printed map produced from it, U.S. Geological Survey(USGS) Geologic Investigation Series I-2789, were based on 31 publishedmaps...
