April 30, 1964 — Canyon Ferry, MT
10:30 p.m. Several children living in Canyon Ferry, Montana, see a lighted, egg-shaped object the size of an automobile land about 150 feet away, then take off. The witnesses are Linda Davis, 11, and children of the Harold Rust family. It leaves four 8 x 10 inch rectangular indentations in the ground, 4–8 inches deep, about 13 feet apart, and a burned area. [Eberhart] Tbh, not sure why Sparks list this hoax as an Unknown, since the AF didn’t think it was.
