Rock paintings in red pigment were discovered in June, 1940, on a bluff where Moose Creek flows into a slough of the Tanana River, eighteen miles above Fairbanks, Alaska. The find was made by engineers of the Army Flood Control Project after trees and brush had been cleared from the face of the bluff in process of obtaining dam material from the hillside. The paintings, some of them destroyed by weathering, others obscured by lichens, represented human figures in various attitudes, and covered most of a comparatively smooth, slightly underhung rock face approximately twenty feet high and fifty feet long. A smaller group of paintings occurred on a vertical rock face higher on the slope.
