Several natural avalanches occurred near the end of last week's warm spell. These two sizable loose wet avalanches occurred sometime after 3:00 Friday 4-11-2014. Most likely later that afternoon.....

These are of a larger avalanche in Hell's Canyon. It was fairly active in the Wellsville Range late last week during the hot weather, but a few freezing nights and cooler days helped solidify the snow this week. Unfortunately, looks like another poor refreeze tonight and warm temperatures tomorrow though.
