Yellowstone Club Ski patrol saw this natural avalanche during a break in snowfall on 2/7/21. Photo: YCSP

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.

This 4' deep snowpit shows the new snow over the last 4 days: everything above the blue card, over 2' of snow measuring 2" of SWE. Avalanches are breaking on the very weak, sugary snow (facets and depth hoar) 1-1.5 feet above the ground. The smooth surface in the bottom left of the photo is the failure plane. Photo: GNFAC

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

From BBSP on 2/6/21" "Clear vis gave us a good view of  natural avalanches on Saddle peak , the Football field and Behind D-rtand the nose on Truman Gulch that ran yesterday morning (2/5/21)"

From Obs: "Big whumf a cracking on south east slope 8000 feet elevation. sub 25 degrees angle. Super loud and scary when it fractured. Broke to the ground. Small crown up higher on same slope." Photo: A. Kaugman

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

Natural avalanche observed near Fairy Lake on 2/6/21. 150ft wide and varying from 2.5-5ft deep. Broke in the new snow but also stepped down to near the ground.
