Slidepath across the road from Slickrock.  Came across this while skinning up today.  Not enough visibility to see from the bottom.  My guess is that it might have run last night, there was very little new snow on the debris which was soft.  The path that ran feeds into the main path.  My guess it came from near the top of the ridge.

Ran at least 1,200’. Width varied based on the shape of the gully, up to 75’.  It did not step down.  I took advantage of the debris for skinning (old habit).  Skied both flanks from 7,100’ or so.  Some sluffing mostly at 40 degrees.  One small soft slab, upper most 4” only, minor it did not run very far.

This path might have a name but being new to the area I am not sure.

1st – Path from down low.

2nd – debris fan, gully that ran is directly above with two small rock bands.  Note main path to lookers left.

3rd- Close up view of path that ran.  The top is not visible.

4th- pole columns were easy to isolate down to a crust at 18 to 24”.

5th- ECTN, column just collapsed.  Note: I got this result twice and one ECTP 25, Q2 which broke on top of crust.

6th- Pit profile, glove points to crust.  Pit at 7,000'.

My take on hazard in this area is mostly moderate with the caveat I did not make it to the ridge.  If this natural was as recent as I think, the hazard could be higher along the ridgetops and in wind loaded terrain.  I would guess considerable.  Hazard will rise with more snow.  I left after my 2nd lap after I bailed on going higher due to an increase in PI, figured a big path not the place to be with it snowing!

Warmer than expected.  It almost seemed like it snowed more at the Lick Creek trailhead, than at Slickrock.
