Numerous avalanches in the north fork of Seeley Canyon released at various stages of the recent avalanche cycles. Pretty much the entire upper northeast facing basin avalanched in 3 different sections.
The upper headwall was the widest of all the slides measuring at least 1000 feet wide. My guess is this came out on Feb 21.
The mid section of the basin looks like it probably released on the Feb 17th cycle.
The lower nose released pretty big also. It's hard to say during which period this one released. Best guess would be the earlier cycle.
