We saw this in the afternoon when we were approaching the CARDIFF pass around 1 PM today saw a significant R1-D1+ from the quartzite slab known as Tetris in the Cardiff chutelettes. Approx size 250-300' length & 100' Wide from quartzite slab to small contour at bottom. Not sure of the trigger, maybe cornice, maybe backcountry user (???) but released from the ridge, didn't observe tracks going in with the low visibility. Looked like natural release. Didn't think much of it at the time, hence no photos. We thought it was from previous day until I saw a friends picture from 10-11am this morning, then I realized no one had reported it yet.

Depth of the debris was approximately 290cm and 9.1 feet.
