This Saturday we drove around 30km north on the Icefields Parkway (Hwy. 93) toward Jasper to the Helen Lake trailhead. The trail heads around the mountain up into an alpine meadow to Helen Lake. We continued on up over the ridge to get a view of Katherine Lake & Dolomite Pass; however, as we made it to the top of the ridge a storm blew in causing us to turn back earlier than planned.
Before I put away my camera, we saw several Marmots, some of whom were doing what looked to be wrestling: They stood up on their hind legs, did some sparring, then they would pull some form of shoulder throw before rolling around some more. They were very entertaining.
Here are some photos from the hike:
