Class B First-hand BFRO #21907

Possible sighting and wood knocks heard near Swan Lake

30 October 2007 afternoon between 2-5pm Swan Lake, Flathead County, Montana 1 witness

Account

The witness was hunting with companions in a pine forest with a ravine when the group split up. The witness caught a brief peripheral glimpse of something brown moving behind a tree to the right, then repeatedly heard loud wood-on-wood knocking from that direction that later stopped abruptly. While walking back toward the road the witness heard a single whoop-like call that the companions did not hear.
