Watch for moose. Seriously. We were in the dark with headlamps and I spotted eyes about a hundred feet away. A bit later we saw two young moose on the trail. While we were heading out, we lucked out and caught this video of them sparring. We’ll probably never get this lucky again. Also keep an eye out for stoats near the glaciers. One popped out from some rocks and ran off before I could even think about grabbing my camera.
Moose! Apologies for the grainy photo.
Looking around at dawn:
