Headed up toward UFO bowl via Aspen Grove around 1pm on 4/2. Decided to turn around at 9000ft on the ridge due to worsening visibility and intensifying snowfall. Put a pit in @ 8500 ft that showed good overall stability, however, there is a minor weak layer @ 70cm and a more significant layer under the most recent storm @ 20cm. This layer failed ECT21 without propagation. Slope was 38* and 10* North with air temp @ 38 degrees. By the time we returned to Aspen Grove it was raining hard and the snow had become extremely saturated.
