This scene, recorded late in the fall from a beaver dam at Voyageurs National Park, features all four of the critters in the headline. Of particular note are the otters and their delightful belly slides across the ice.

The footage is from the Voyageurs Wolf Project, focused on understanding the summer ecology of wolves in the park. At the end of the clip, one of the wolves becomes interested in the trail camera and takes it down to chew on.
