An object was observed. Occupants of the craft were seen. Ground traces were found. Animal reactions to the object were reported.

One ball, about 40 feet across, was observed by five witnesses one of them independent in a yard for five minutes (Chaput, M; McQuirter). A purring sound was heard.

Hynek summarized:

M. Chaput, a pulp mill worker, was awakened on his ten-acre farm at 2 A.M. by the barking of his dog. Looking outside he saw an intense light source illuminating his field about 600 feet away. It was so bright that it lighted the surrounding area, even the house. He went outside and could see his shadow cast on the house. Chaput said he felt that the light could not have been more than 15 feet above the ground. Then the light vanished, but he could hear a purring sound receding in the distance.

The next morning he went to the scene of the incident with one of his teenaged sons and a younger child and found not only a circular mark of the "traditional" type but "three circular depressions, equally spaced to form a triangle with a rectangular depression one to two inches in depth," near the midpoint of the base of the triangle.
