Pacific Northwest Geologic Mapping and Urban Hazards

Physiographic Maps

The shape of the earth's surface is the primary recorder of the physical processes acting to produce the landscape. Mapping the surface in detail provides clues to the advance and retreat of glaciers, rivers, and oceans, earthquake effects and landslide processes.
