Summary
The author has identified the following significant results. Rapid construction of a lineament map for western Montana, drawn as an overlay to a late August band 7 mosaic at a scale of 1:1,000,000 indicates ERTS-1 imagery to be very suitable for quick compilation of topographically expressed lineaments representing scarps and straight canyons. Over 100 such lineaments were detected, ranging in length from 80 down to 5 miles. Most of the major high angle faults of the area are represented, but low angle faults such as the Lewis overthrust are not apparent. Short and medium length lineaments of northeast trend are abundant southeast of a line connecting Missoula and Great Falls. Only about half of the lineaments are shown on the state geologic map, and limited comparisons with more detailed maps suggest that many will merit investigation as possible faults. It is already apparent that ERTS-1 imagery will be useful in construction of a needed tectonic map of Montana.
