Light snow and lingering clouds most of the day made it hard to see this slide clearly but there was definitely a repeater in upper Bunnells in White Bimbo, the northern most bowl along the Cascade ridgeline. Most likely timing was very early morning on Dec 27. From a distance and through the clouds it looks to be at least 400' wide with exposed rocks at the ground. This slope recently avalanched during the storm on Dec 17. I'm afraid this may be an indication of the lingering instability in the upper elevations of the Provo area mountains. I spent Thursday on the Timpanogos side of things and did not see any signs of activity during this last storm in the larger paths. Heading towards Cascade on Sat with hope of getting more of the alpine picture.
