Observer Comments

Recent avalanches on Sunburst, Tincan, off of Seattle Ridge and possibly above the Seattle Ridge uptrack. Roller balls on Petes South. Visibility wasn't great. Flat light. Avalanche cycle was less widespread than expected but some evidence of crowns may have blown back in or some slopes may not quite have reached the tipping point. That is the spooky part with a buried persistent layer, definitely guilty until proven innocent.

Some channelized paths along highway and across the Turnagain Arm had fresh debris in them.
