This morning on the way up to circle all peak there were several small avalanches that appeared to have released naturally overnight. These were mostly located on the southwest facing steeper terrain on the East side of the normal skin track right off of the Butler Fork trail head. The largest on was likely around 70 feet wide and definitely large enough to knock a person off of their feet into the terrain trap below. I measured the slope angle in a couple of places and found it to be about 45 degrees where the slides occurred, with crowns about 8-10 inches deep. The cause of the slides may have been due to the upside down new that was noticeable throughout the morning forming a small slab that slid on the new snow old snow interface, although I didn't have time to dig into the details this morning. Overall a minor slide here that could be very telling for bigger, steeper terrain today.
