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

By Harry W. Campbell and Paul C. Hyndman

1996

Summary

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.

Map sheet size is approximately 26 by 30 inches. The maps are oriented with the long axis in the x-direction for plotting. This map was designed to be plotted on a HP Inkjet Plotter (model 650-C), but can be plotted on any full-color (inkjet or electrostatic) plotter that will accept HPGL2 code.
