Comments

Using binoculars in Ogden, got a good look at the South face of Ben Lomond and West-facing mountains to the south towards North Ogden Divide.  Also looked at the West side of Mt. Ogden above the city.

Observed numerous, fresh wet point releases.  A dozen or more of these triggered larger, wet sluffs, deeply filling in gullies and running 400-800 vertical feet.  These were on Northwest through West through South aspects.  Most of the large gullies I looked at had some form of wet debris in them.  Nearly all steep, rocky areas appeared to have rollerball activity - literally hundreds off of a single cliff band.

I did not observe any wet slabs or anything that looked like it stepped down to weaker layers.
