Geologic datasets for weights of evidence analysis in northeast Washington--3. Minerals-related permits on national forests, 1967 to 1998

Permits to explore for and (or) develop mineral resources on
Federal lands can be used to indicate locations and types of
mineral-related activities on national forests. Permits for these
activities require filing of a Notice of Intent to conduct mineral
exploration activities and (or) a Plan of Operation, if
significant land disturbance results. This compilation of notices
and plans for the Colville, Kaniksu, Okanogan, and Wenatchee
national forests between 1967 and 1998 is intended for use in
combination with geologic and economic information to predict
future mineral-related activities in the region.
