Observed a fresh slide on the north side of Mt Blackmore, crown was already filling in, but looked to be a foot or two deep in steep rocky terrain to the skiers left of the north couloir. Photo: S Jonas

Lots of snow moving around in Hyalite this morning! Strong winds were moving snow at/above treeline, Lee aspects getting loaded. Photo S Jonas

Saw cracking of cornices on the ridgeline NE of Mount Blackmore. Just a little nudge released a significant portion. Photo: T Miller 

Natural avalanche spotted from the air on Red Mountain, just west of Ernest Miller Ridge

Surface hoar was on the snow surface today. It likely wont' survive to be buried. Sunshine on south aspects was already destroying it.

Snowpit and ECT result from small slope just above Beehive Creek at 8200 ft. 

Facets in thinner snowpack areas are larger, weaker, and could possibly cause an avalnache

Snowpit from the top of Tyler's slope in Beehive Basin, W facing, 9200 ft. This is representative of an area with thin snow that is weaker

On Tuesday, January 19, 2016, a Yellowstone Club (YC) Ski Patroller triggered an avalanche on a wind-loaded slope which released on his second turn. The slide broke 2-4 feet deep, 300 feet wide and carried him through a terrain trap of thick trees. He was partially buried 300 vertical feet below in the toe of the debris. His partners reached him within three minutes, but the trauma was fatal.

The YCSP created a non-profit to remember their colleague and friend, Darren Johnson. And, to support ski patrollers across the country by providing scholarships for avalanche education and attendance at the National Avalanche School.

Woody Ridge north of the "KNBs." Northwest facing slope, crown elevation approx 9600'. Ran 1000 to 1200'. Unsure of when it went, we did not notice it this morning only this afternoon on the hike out. Photo: N Gaddy

We saw a large avalanche (SS-R3-D2-O) that broke on a north facing aspect, around 2' deep, on weak snow near the ground. Photo: GNFAC

Observed a large avalanche on a west facing slope approx 10000ft, with a higher crown at 10200'. Crown depth 4-6'. HS-Ns-D2-R2-O . Ran 1000ft and into terrain I had previously considered safe. Photo: N Gaddy
