Very interesting location. I usually spend the night in this area in my car when heading out west (there are several rest areas to choose from). It’s in west central Minnesota on I94(about 50 miles from Fargo)and nowhere near the BWCAW or the Chippewa National Forest.
Seifert can’t confirm it was a cougar, but says the injuries suggest a very large animal attacked the horse, and that the injuries are consistent with the way cougars attack prey.
