Northern Gallatin

On 2/7/21 skiers in Beehive reported: "Numerous large collapses, ECTP in several pits on mid-pack facets, and triggered a test slope remotely from flat terrain. It broke in the old snow, but towards to top, maybe 10cm below the interface with the last week’s snow. Propagated over 50m, crown depth 60-100 cm. Would be solid size 2 if the slope wasn’t 20m tall." Photo: Sam H.

From obs 2/6/21: "Natural slide below Maid of the Mist (unless someone was up climbing Maid No More...). E/NE aspect, roughly 8000' elevation. Looked to have run last night or early this morning. Poor resolution iphone photo, but gets the job done. Photo taken from the base of the Dribbles." Photo: M. Zia

From obs: "Skied up into Divide Basin today... Observed 2 natural avalanches on the N face of the cirque, one quite large.... Shortly after digging the pit, on the same slope 30’ above it we triggered a slab that cracked but did not move..." Photo: J. Dalimata

Froma skier that tooured in divide cirque today. "In the basin, between pt 10,201 and 10,024 there was a very large avalanche that must have slid yesterday or last night. It looks like it propagated at least 1000’ wide and at the deepest the crown was easily 5 feet. Visibility was low so it was hard to tell, but it was definitely a big slide." Photo: N. Salsburg

Skied up into Divide Basin today and holy shit there is so much snow! 3’ of new on top of a crust that is present on S faces and not present elsewhere that we found. Observed 2 natural avalanches on the N face of the cirque, one quite large. There is a picture of those. Also observed another natural avalanche on the SE face of the cirque that I was unable to get a good photograph because of clouds. We dug 2 pits and got an ECTX on both (one at 9300’ - 270 cm of snow, one at 9500’- over 300 cm of snow) on S/SE facing slopes less than 20 degrees. The one at 9500’ we had a hard time sawing through the hard crust that is under 3’ of new snow so it probably isn’t very accurate. Shortly after digging the pit, on the same slope 30’ above it we triggered a slab that cracked but did not move. Turned around right there and left. A good example of how feedback from pits is not necessarily the end all be all. I think the new snow will become more reactive as it settles into a more cohesive slab. We kept it overly conservative and I just want to say I appreciate you all!!!
