As they were passing through Lake Elmo, Minnesota, on their way to Hudson, Wisconsin, Frederick Chamberlain & O. L. Jones spotted a shadowy figure in a clearing two blocks away. The figure carried a lantern and seemed to be looking for something. Thinking there might be some emergency, Chamberlain & Jones turned toward the clearing, but the figure & lantern disappeared into the trees. Moments later they heard the crackling of twigs and branches, followed by a rushing noise, like the wind blowing around the eaves of a house, Chamberlain later told the St. Paul Pioneer Press. A second later and we distinguished a long, high object of a gray white color.
Although the 2 could not get a clear view of it in the darkness, the object, which had 2 rows of red, green, & white lights on each side, looked like most of the top of a prairie schooner, Chamberlain said. It rose at a sharp angle, then headed south just above the treetops.
At the clearing, the pair found, impressed in the wet ground, fourteen 2' long prints, 6" wide, and arranged in an oblong pattern 7 on a side, Apparently, traces left by the craft. Around that same time Adam Thielen, a farmer in the Lake Elmo area, heard a buzzing sound above him. When he looked up, he saw a dark object with red and green lights sailing overhead.
