Comments
Fairly sizable hard slab in Mineral Fork. Appeared to have slid a few days ago. Crown ranged from 3'-10'+ From a quick look it seamed to go just above the MLK (Jan 16th) crust. Ran down into the basin. Photo by Ty Falk.
Bruce Tremper comments: I investigated it the day after these photos were taken and my snow profile suggests that it broke beneath the MLK crust on facted snow. I did not investigate the entire fracture line but I dug on the looker's right flank. (see video).
Comments
Next three photos by Spencer Wheatley. Note total width and long runout.
