Spring and fall bring weather systems together in Rogers Pass, BC. The rising dampness at dawn slowly gives way to a thick soup of clouds shifting on the winds.

I set up on a paved offshoot, a little clear spot where Canada's Armed Forces mount the big guns during winter for avalanche control. I waited in the London-dense mist as it slowly brightened from a deep battleship grey to a whiter shade of pale as the sun, lost high above, slowly cooked off the damp.

Forty-five minutes ticked by until a break appeared like parting bedsheets, and lo, there lay frost-shrouded Ross Peak in all its minimalist splendor.
