A skier in Hyalite reported many signs of new snow instability near Mt. Blackmore. From the email: "Widespread shooting cracks and wumphing. Lots of dry loose activity in steep terrain. I saw what I believe was a crown line near the ridge on the north face of Blackmore but it was hard to see because it was in the shade. The wind was gusty and not very consistent, so those wind affected slopes didn’t appear to have set up into harder slabs yet, but I wasn’t about to walk out there to find out!" Photo: H. Coppolillo
