According to the BFRO, a dark, long-armed figure stood up and walked away from the edge of the river as the two whitewater row boats passed by. The location of the incident, and the physical appearance of the figure, and the behavior of the figure are consistent with a sasquatch. Nothing about the figure, or the incident in general, points to a hoax or a case of mistaken identity.
The Three Sisters region of Oregon has a long history of sightings and track finds.
At first glance the figure appears to be a bit larger than the human in the rowboat, and the figure is certainly not closer to the camera than the rowboat.
The behavior of the figure is consistent with a sasquatch. Sasquatches are often spotted near creeks and rivers.
NOTE: I grabbed screen captures during a 4-5 second period of time (between 1:41 – 1:45) on the video. What are your thoughts? Lon
