Weird Holes in Iowa

Some UFO discs have said to have landed in Alaska on the snow in deserted areas. Wendell Stevens notes this was documented by the US Air-force running missions out of Alaska, during de-briefing sessions. It interesting to note that there are triangular indentations, and a round shape in the snow and ice, with no footprints round about. Many trace cases have the round shape and the triangular shaped 'landing gear' - which leads me to believe this may have been caused by a saucer.
