Abstract
The Quaternary Geologic Map of the Ottawa 4 degree x 6 degree Quadrangle
was mapped as part of the Quaternary Geologic Atlas of the United
States. The atlas was begun as an effort to depict the areal
distribution of surficial geologic deposits and other materials that
accumulated or formed during the past 2+ million years, the period that
includes all activities of the human species. These materials 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 one way or another to
these surface materials that are referred to collectively by many
geologists as regolith, the mantle of fragmental and generally
unconsolidated material that overlies the bedrock foundation of the
continent. The maps were compiled at 1:1,000,000 scale.
