Observed a snowmobile triggered avalanche today. East facing slope, approx 9700', between Fischer Peak and LuLu pass. Rider was not caught. HS-AMu-D1-R1-I. Observed lots of wind transport and loading from strong w/sw winds today.

On Feb 23 We went up Republic Creek to look at the stability of snow that has fallen over the last 2-3 weeks. We were able to easily to trigger a couple wind slab avalanches on test slopes. Photo: GNFAC

On Feb 23 We went up Republic Creek to look at the stability of snow that has fallen over the last 2-3 weeks. We found a thin layer buried 2’ deep that showed potential to propagate and slide. We dug down 4 feet, just below the dirt layer that was deposited earlier this month. We got an ECTP30 that broke about 8" above that dirt layer. This was either on a thin layer of facets or preserved lower density dendrites. Photo: GNFAC
A rider triggered a slide on Saturday (2/22) on a bench below the east face of Mt. Abundance... Trigger point was from the top while driving by. 2' deep, 250' wide??
We went up Republic Creek to look at the stability of snow that has fallen over the last 2-3 weeks. Skies were overcast with light snow falling most of the day and winds were moderate with strong gusts.

We heard of an avalanche that was triggered yesterday which broke 2’ deep and 250’ wide, possibly on this same layer, on an east facing slope by Mt. Abundance.
The wind was blowing new snow into fresh wind slabs. We were able to easily to trigger a couple wind slab avalanches on test slopes. More snow is expected tonight and tomorrow which will increase the likelihood and size of wind slab avalanches, and the added weight could cause a 2-3’ deep avalanche to break a couple hundred feet wide. Be cautious of steep slopes as new snow and wind build slabs over the next couple days.
A wet loose avalanche occurred sometime today between 11-2 pm on S facing terrain nearby
