Avalanche: Turnagain
Location: Seattle Creek, Portage, Placer Valley
Several human triggered avalanches were reported in Seattle Creek and a possible natural avalanche. Details are still vague, and there have been no reports of burials or injuries. There was also a Natural avalanche in Portage Valley at 5:10pm that was captured on DOT web cam. Another observer sent us photos from Placer/Squirrel zone of the natural activity that occurred during the storm cycle last week. The Debris and gauging is impressive. A BIG THANKS to all those who sent us photos and shared some info!!! If anyone has more details please consider submitting an observation HERE.
