On Monday night, Jan. 20, 1969, Erik Marsboll, 44, a truck driver employed by Mt. Nansen Mines reported seeing 2 sets of UFOs at miles 5 and 15 of the mine's road near Carmacks. At mile 5, he saw 2 objects the size and shape of 45-gallon drums. They were light blue to turquoise and their sharp, clear brightness seemed to exceed that of a 19-candle power light. The UFOs swooped down from the sky and hovered over the valley, sent down beams of light of the same color, but not of the same intensity as themselves. They were visible for 2 or 3 minutes and were about 1 mile from the ground and 20 miles from his observation point. At mile 15, Marsboll glanced to the right of the road and saw 4 objects of a similar description spaced equidistant in the sky and coming towards him in a line.

Suddenly, they seemed to form a tighter line and as turning into one blue light and fading out. They were 500 feet off the ground, and the sighting lasted 1 minute. The sky was clear and dark.
