As expected the rapid increase in temp was too much for many of the sun exposed slopes today. There was a widespread WL cycle throughout the Provo region today starting at about 11:00am at the mid elevation SE aspects and continuing later into the upper elevations. We saw wet activity on everything from due east to south. We were a little slower getting to our objective at the top of Slide Canyon than we would have liked and subsequently triggered this WL-ASu-R1-D2-O slide after my first three turns. The snow surface was firnspeigel so I didnt think I would get anything going until lower in the drainage. Once I saw my sluff gain mass I pulled up and let it go by. It slowly gained speed and entrained more snow, gouging in places, until it came to rest about 1700' below. Small slide on the scale of the drainage but definitely not one to get caught in. First pic is an overview taken later from the south fork road, second is from about half way down the slide, and third looking back up from near the toe.

Several other WL-N-D2's occurred today. None huge, but still noteable. Below pics, White Limbo in Bunnells at 10,700, SE, and Middle Finger adjacent to Sundance at 9800', E.

Comments

These last three are in Roberts Horn between 10,000' - 10,800', E aspects. Noticed several glide cracks today also.
