Description

In the early morning of March 17, 1981, Sergeant Russell Yokum of the Saint Helens, Oregon Police Department, noticed an unusually bright light moving upriver. Initially thought to be an aircraft, Yokum soon realized it was not. Along with other law enforcement officers and Ricky Cade, the light was found to be a manmade light on Sauvie Island, with fog creating a bobbing effect. The actual light was low and standing out starkly over the river, emitting an eerie, extremely loud sound. The sound, recorded on tape, displays two strong peaks at about 1000 and 3000 hertz, with no even harmonics. Investigators from CUFOS interviewed the officers, who described the light as spherical, orange-red in color, hovering 80 to 100 feet above the river, and approximately 30 feet in diameter. The sound changed pitch before the light vanished at 4:43 a.m. Despite ruling out various possibilities, the event remains unexplained, leaving the question of what was that light and sound over the Columbia River.
