Rode up cottonwood creek on the west side of the crazies. Saw several recent wet loose slides on southern aspects as well as some isolated slides on north/west aspects. Only saw one larger slide that had a wide crown(500ft) D2 on an east aspect.  All slides were breaking in the upper 40cm in new/old snow.

 

Dug a pit north east aspect HS270cm ECTN24 @40cm down from surface. Melt freeze down 70cm might start reacting when water penetrates through upper snow pack, dry snow in upper 60cm but becoming more moist on solars.
