Twin Falls, Smoke River Canyon (Idaho) — August 13, 1947 (1300)

Two boys and their father saw a sky-blue object 100 m away and 25 m above ground. Treetops under it were spinning wildly, although the object itself did not spin. It made a swishing sound. Shape: inverted plate, 7 m diameter and 3.5 m thick. There was a red flame on omic side of the top. (Atic)
