Climbed Mt Athabasca up and down the ramp / N glacier route yesterday. There is less snow than I've ever seen up there currently. The footing going across the ramp was mostly quite good, with about 10cm of wet recent snow overlying warm and soft older snow.

This and all other areas with permanent snow and ice are rapidly changing this summer. The firn snow forming the upper part of the glacier was isothermal or at least very soft in many locations, allowing me to sink my entire pole into it. Usually this multiyear snow is very firm and strong. Glacial features that I would typically walk across with lots of confidence are seriously weakened, often eroding from the inside out.

Be especially careful of what you're walking over these days, as our glaciers seem to be absorbing unprecedented amounts of heat this summer.
