On my tour today I did not have any other signs of weakness, but while descending back to the North Ogden Divide Parking I took a few turns and kicked loose a relatively small slide.

L-AS-R1/D1-I (loose snow, artificially triggered by a skier, relative size 1, destructive size 1, failing on new/old snow interface)

Bed surface appears to be the 20190117 rain crust. Also noted another natural point release on the same aspect at approximately 6500'

Photo 2 shows the prevalent ice crust from the 20190117 rain event. this crust is near the ridge line at 8000'
