Rapid Warming, Trigger Run, Repeat.
While I was working on the dugway, I heard the first avalanche run down the West Branch of the Crows Foot Couloir. (at 11:50 am) It was triggered by heating but still fairly dry. It repeated over 10 times in the next couple of hours. At some point the Grr Couloir ran lower. I saw a minor repeat later.
I had a needed snack at the West Campground. Then spent some time packing 150' of the trail East. Things started hoppin'. The open patch East of the Campground avalanched, shallow & dry. (map pin) It widened out to 200' and swept to the bottom. The cascades on the steep cliffs East & North started triggering with the afternoon warming. I lost count,, a bunch. One fanned out off a 200' cliff. Then a larger rumbler shot out in profile with darker gray. (usually larger ice facets) The next 45 minutes I saw or heard one cascade after another. Most notably on the West Southwest aspect. And silence to the South from Provo Peak's NW flank.
Eventually it was time to bug out. As I dropped lower the signs of afternoon warming increased. The dugway slope formed some very large pinwheels. A pair on skis would kick up some damp snow when they cut into the pack next
to the trail. Some steep north aspects had fresh rollers. I watched a cluster of rollers coming down Hale Draw.
With the increasing temperatures the next four days, I'll probably head somewhere without overhead concerns this weekend.
