Just returned from the area with an observation of the goat lake area. The area is now completely devoid of snow. Wolverine are adapted to the snow so this is a condition that doesn't facilitate their habitat.
And a lesson I learned the hard way: During my third evening I was treated with a delightful movement of 36 mountain goats across a cliff face in single file above the lake.......it looked scary to me but they all made it seem very routine, both the very young and the old......so I went for my camera and, Allah Akbar, I had the black screen of death. New Canon camera and nothing but a black screen. If I'd had a film camera I could have worked around the problem but a digital camera, not so. So lesson learned.
