Wholly Sastrugi

South Ridge of Mt. Andromeda. The Athabasca Glacier ramp detour route is in excellent shape, with 2–3 m snow depths. Skiing down the south ridge requires a mouthguard and strong knees—the sastrugi game is real. Anything below 2400 m on the ramp turned into nice, soft spring snow by the afternoon. We did not observe any recent avalanche activity; however, there was fresh-looking serac debris on the ramp below the frequent flyer.
