U.S. Geological Survey Open-File Report 96–737

Digital Mining Claim Density Map for Federal Lands in the Pacific Northwest

By Harry W. Campbell and Paul C. Hyndman



This report describes the contents of a digital dataset (approximately 25 MB) which consists of ARC/INFO Export format files and associated macro programs. The dataset includes a mining claim density map of the Pacific Northwest (Idaho, Oregon, and Washington). This data was acquired from the Bureau of Land Management in September 1994. The user may analyze the four types of mining claims—lode, placer, mill, and tunnel. “Open” vs. “Closed” claims are also two other categories that can be researched. "Open" claims are those actively held when the data was acquired. “Closed” claims are those no longer held by claimants.
