Natural slides blue lakes

Arrived at blue lakes parking around 9am - temperature was 39f. The snow near the parking lot was quite firm and I could not penetrate it with my boot or sled. It stayed like this off trail until about 10:15am. In the trees it was a mix of supportable crust and knee deep boot pentrations. Snow was warming rapidly - by 11am it was quite wet and I was back to my car by noon. The trail out for the last mile is melting rapidly. 

Observed three slides, all looked natural near polaris bowl. Unsure when they happened.
