- <p>One minor collapse on a NE facing test slope slope at 8500' elevation; failing on the old snow surface of facets. Crack propagated perhaps 30'; breaking 10' above me. Last photo below.</p>
Timp Divide at roughly 8200' sits at 54% of median and as such, the total snow depths of 12-18" along this elevation band is either dry (many solar aspects) or facets and depth hoar (and occasional crusts) top to bottom. It is the weakest snow I've seen from Ogden through the Cottonwoods to Provo. The difficult of access (aka "thicketeering") would make old Provo forecasters Bill Nalli and Rip Griffith proud.
The storm snow at the low and mid-elevations did not appear to be enough to tip the scales regarding the very weak pre-existing snow surfaces. Still, it was noted the in the thin snowpack, ECTs revealed ECTN1 multiple times at this new/old interface with PSTs arresting easily. There clearly lacks a slab in many areas. Still, the highest elevations and/or areas that received the most snow would be suspect.
Snowpack
Sundance Mid-mtn reported 12"/0.60" for the storm with nearly all of the snowfall arriving pre-frontal as is common here. Storm totals were more like 3-4" north of Aspen Grove at similar elevations.
