But my recent attempts have failed - it just hasn't been cold enough. This one from the Hollyburn cross-country area as the clouds rolled in was close, just below 0C, but not quite enough to freeze the paint.
Even Edmonton, on the last day of November - this should be the world centre for ice-colour painting - came in well above freezing as I drew the river from a pedestrian bridge.
And back on Hollyburn Peak, mid-December now, it was a sunny +9C with a warm breeze, in a strong inversion that was blanketing Vancouver below in fog. It was so warm that I skied up the rapidly melting (but still deep) snow in a short-sleeved shirt, and people on the peak were dancing around in their underwear. (There are still a few eccentric and exuberant people left in this age of internet shaming). I am wondering if the days of ice-colour painting are numbered...
