This clip from July shows the Wiyapka Lake wolf pack — which includes six pups — walking an old railroad grade in Voyageurs National Park, about 110 miles north of Duluth. At the end of the clip the wolves can be heard howling.

The video was captured by a Voyageurs Wolf Project trail camera. The project is focused on understanding the summer ecology of wolves in the park.

The Wiyapka Lake pack formed in early 2019, when a breeding female and her mate produced a litter of five pups. Just one of those pups survived into adulthood, but died this past summer of unknown causes. Six more pups followed in 2020, but all of them perished. The third litter in 2021 produced six pups, all still alive at the time of this video.
