Storm slab couldn't take the heat

Saw the aftermath of a size 2 at Eagle Pass riding area. No tracks were observed to have triggered it. Looked natural maybe had the help of a sled track 25m away. Many existing tracks around the slide area and on similar slopes. Saw a total of 5 slides on the storm layer, this one being the biggest and closest to riding zone. Crown depth was ~60-70cm at center and down to 25cm on outside. Weather was sunny and bluebird, lots of heat on snow. Very easy to make a snowball.

Very warm day. No bellaclava's, T shirts under jacket
