Big change in conditions last 14 days in Lake Fk. of Rock Crk. Cyn. Snowpack essentially gone below 2200m. Thin up to 2450m where we turned back on our run. The record 4-day MAR warmth last week accelerated the already too far along spring melt. It looks now what late April/early May used to look like. Buds on Cottonwood/Aspen are swelling. Crk. is much more open, rotting ice. Didn't need spikes, trail ice soft now. 11C lite breeze at 2080m start. #climatecrisis #running #montana #dogs
