Avalanche conditions seem quiet but the weak snow still lurks near the ground. While riding my snowmachine Friday, I came to a stop. Two more riders approached and stopped. Two more riders were approaching when the snowpack collapsed, WHOOMP!, and we all felt the snow drop an inch or two below us. This is the Persistent Weak Layer of snow that formed early season and is still a concern. It is quite unusual to be experiencing collapsing like this still this late in the season. Again, things seem quiet as far as avalanches and it seems somewhat unlikely to trigger something but these collapses I've experienced this week along with poor snowpit test results don't give me a whole lot of faith in the snowpack.
