The cracking and collapsing were top notch today- thunderous collapses and cracks shooting 100' easily. The strange thing was that we couldn't get anything to move- kept coming up on slopes thinking this one will slide for sure, big collapse, shooting cracks, cut a cornice, nothing. We weren't in very steep terrain, but it was easily avalanche terrain, several slopes mid to high 30's, obvious avalanche paths, and we couldn't get anything to move. Still, we're no dummies, we kept our exposure to a minimum, but still... maybe some friction at the interface from the storm coming in so warm? Digging down in it looked like most of the collapsing was in the NSF from before this storm, and depth of cracks/new snow were routinely up to 2 feet.
