I did not have or take the time to dig any snow profiles but I shoved the handle end of my ski pole into the snow dozens of times and I needed to shove it the full length of the pole to punch through into the basal depth hoar layer. In other words, total snowpack depth is over 150 cm in most places and the depth hoar is buried under a meter-thick, very stout slab. So, it's probably difficult to trigger, but if you do, it's a very large avalanche.
Photo #1 is the northwest face of Red Baldy and you probably can't make out the track of a solo skier breaking a trail into the steep, upper elevation terrain and taking a couple runs down, all without triggering anything. Photo #2 is Tri Chutes and there's quite a few tracks in the apron of the runouts, which is all under 30 degrees in steepness. A couple other parties put tracks into 35 degree, north facing terrain off of Lake Peak. (no photo).
