This avalanche was one of a number that occurred in the Logan zone in the afternoon of President's Day. Temperatures were extremely warm and there was rapid heating by both greenhousing and direct sun. Overnight temperatures had stayed above freezing for the previous few nights. The area had also received a fair amount of water Saturday night through Monday morning in the form of rain and wet snow. The snow was extremely saturated and unstable.
It did not hit the popular multi-use Green Canyon trail but did come within a couple hundred feet.
