Report of a natural slab avalanche came into the CNFAIC from the Surprise Bowl area. This zone sits below Goat Mountain. Fresh debris from this slab was reported to have been seen in the afternoon of March 5th, between 1530 and 1600. The reporting party could not get a good look at the start zone (their photos below) but Heather Thamm (CNFAIC forecaster) was across the drainage and took photos as well. This avalanche was likely a wind slab that was triggered by the bump in Northerly winds during the day. There are many older wind slab avalanches that have occurred in this area over the past week during the strong Northwest winds.

Limited information at this time.

A zoomed in look at the slab that sits to the far right of photo. The small slab in the center of the photo under the rock band released at an unknown time and could be old.
