Hunter sees black creature dive into the Sioux River near Washburn

May 2008 4-5 p.m. Washburn, Bayfield County, Wisconsin 1 witness

Account

The witness was walking downstream along the Sioux River after trout fishing when he noticed a small black furry creature on the bank ahead. The creature immediately launched itself arms-first into the deepest pool and disappeared underwater without resurfacing during several minutes of watching. The witness did not inspect the spot for tracks and continued out to his car, remaining puzzled about what he saw.
