My video coming out this Friday features the Tawayik Lake Trail. Although it was a half-loop we had a lot of bison sightings. The first image was me demonstrating the rule of thumb - holding your arm out, if you can "cover" the bison in the distance, then you are generally at a safe distance. As a sidenote, this bison appeared pregnant to me.
The second image is of me lying in the middle of the field, looking at the bison in the third image. It was an amazing day.
