The geology of the Sandpoint 1:250,000 quadrangle, Washington, Idaho, and Montana was mapped by F.K. Miller, R.F. Burmester, D.M. Miller, and R.E. Powell between 1963 and 1995 onto a scale-stable 1:250,000 topographic map base and subsequently input into an Arc/Info geographic information system (GIS) by P.D. Derkey. The digital geologic map database can be queried in many ways to produce a variety of derivative geologic maps.
