A quick general ob from 2 days of sledding and skiing near Deadwood Summit. Primary red flag would be the warm weather. Damp/wet snow on solar aspects out of the valley bottoms. Some wet snow activity such as large roller balls and wet sluffs on south facing areas off of the rocky areas on the Warm Lake side of the pass.
Surface hoar on many shady aspects. We observed one old crown on a steep north-facing ridgeline at 8,200’. No signs of instability while traveling from 6,800 to 8,400’ over the last 2 days. I was able to imitate propagation in a couple of quick hand ECTs in areas with shallow wind slabs. The shears were rough and not very clean. It would be possible trigger a wind slab in upper elevation terrain. Basal facets exist in most northerly areas. HS in this area was approximately 48” which is a bit less than the Deadwood Snotel site HS of 54”.
Overall, I would say moderate hazard, we avoided and steep wind loaded or thin snow pack terrain. We were able to safely ski a few rollovers approaching 40 degrees.
Cold in the valley bottoms!
