Chickadee-dee-dee-dee in the Deep Freeze


Published in the The Fitzhugh, December 3, 2014 Imagine going to bed, and waking up having lost 30 per cent of your body weight.

This year, however, the tops of some of the spruce are so laden with cones, it seems possible that with one good blast, they might just snap off. This phenomenon can be seen everywhere around the park, from the middle of the townsite, to the sub-alpine near the Columbia Icefield. From a distance…
