Toured into the southern Lionhead today. Yesterday’s warm weather made the snowpack more moist, and the upper snowpack was much more cohesive than in days past. Snow was glopping on skis and skins up to around 9k. I got on NE, E, and SE aspects, which were quite reactive, with more wumphs than in the last few days.

Skiers on Monday, Dec. 18 felt collapsing in the Lionhead area. They also saw an old avalanche. It likely occurred at the tail end of last week's storm. 

From obs: "Saw one small natural crown on a NE rocky outcropping around 8k, 1 foot deep and isolated. Felt a lot less collapsing than last weekend, however still found some instabilities. Notably a remote collapse that propagated around 50’ in length at around 8200’ on a NE aspect."

An avalanche along the divide between Muddy and Bear Creek. Avalanche was approximately 100 ft wide and 25 ft tall, breaking on facets just above a crust near the ground. Slide was clearly several days old, estimating it broke Friday, 12/15/23. Tracks indicate it was likely snowmobile triggered. Photo taken 12/19/23. GNFAC

Big Sky Ski Patrol reported two natural avalanches seen today (12/15) in closed terrain. 

From email on 12/16: "Further investigation of the avalanche yesterday showed goat tracks leading into the crown area of the avalanche. At the debris pile, it was obvious that a goat had taken the full ride in the slide that it triggered. There was a depression in the debris pile where the critter had come to rest at the surface, and obvious hoof prints trailing away from the debris pile, and then upslope for the long walk back up to rejoin the heard. There was no blood, and the tracks looked usual, with no obvious sign of broken leg(s). It is unknown if the goat was wearing an airbag or if it was deployed in the avalanche. It was a significant ride, 1K’ vt., 1⁄4 mile linear, likely of high speed, through 2nd Dictator transition, which was taken down to mostly bare ground."

Two natural avalanches observed near Lionhead on 12/15 and another two observed by a separate group on 12/14. All occurred well below the high ridgelines and likely broke several days earlier. 

From obs:"We rode up Denny Creek towards Watkins Creek and spent the day below the ridge where we saw two natural avalanches. These avalanches broke 12-18" deep on weak faceted snow above a stiff crust. The first avalanche presumably happened sometime near the end of the last storm cycle (12/11), as it had a few inches of snow on the debris. The second was more recent, in the last 24-36 hours. Both were at 8500' and were on NE and E-facing slopes. "

Spent the day up near ski hill with West Yellowstone Avalanche Fundamentals course. 

Our group observed a large collapse below ski hill.

We dug various pits @ 8000' below ski hill and found HS 85-55cm on NW-NE aspects.

The snowpack structure there had weak snow at the ground capped by a stout ice crust with faceted snow over the crust beneath the recent snow.

We recorded ECTP4, ECTP11, ECT20 & a few more propagating results on facets above the crust. 

There was widespread intact surface hoar

Skinned up the closed ski area to the Fingers Meadow above the Pierres Knob chairlift. Got a substantial collapse (whumpf) while skinning and stopped to dig a pit at that location. E aspect, 8100 ft. Snowpack consisted of 6-8" of old, weak, faceted snow at the ground capped by ~18" of snow that has fallen over the last week. 

ECT broke on the old snow while isolating the column. Twice (ECTPV x 2). Clear signs of instability kept us out of avalanche terrain.

Toured up toward Mt. Blackmore today with the goal of skiing the mellow SE facing meadow and familiarizing myself with the current unstable snowpack. While stopping for lunch I dug a quick pit out of curiosity and performed a CT at 8757’ on a NW aspect with HS 85cm. Results were CT11 down 17 cm within the new snow on a hardness change and a CT13 down 35 cm on old facets. Moving farther up in the basin we noticed the pictured recent D2 avalanche on the E aspect of Blackmore. As we skinned up the SE meadow, we experienced three audible whumpfs. Otherwise great skiing was found today albeit a bit thin!

I skied up to  investigate it and would estimate the size of the crown to be 2-4' deep and about 80' wide. Somewhat surprised by the size relative to the starting zone. Likely a natural avalanche (from about 36 hrs ago), but there were fresh sled tracks in the vicinity from yesterday, so possibly a remote trigger."

Was splitboarding up near lions head ridge today. Made some bad decisions and kicked off a good slide in a NE facing chute. Was with 2 buddies, 1 of which skied the line 3 weeks ago.  Underneath about a foot of new powder snow there was a firm crust that seemed like it was old  hard windslab in the gut of the chute, and I think a sun crust on the riders left side(East aspect). We had 2 spots where we were planning to re group at, first was a small cubby area right before a slight rollover about 75 ft from the top. I dropped first, made some turns down toward the pulloff, as I pulled in, I triggered a good size slab that propagated maybe 40-50 ft across, at the rollover as I carved into the pulloff.  Pulled  all snow  out of the chute down to the ground. Seemed to have failed on sugary facets on ground/ice crust close to the ground...

Skied around Mt. Henderson today. Was finding around 28-35 cm of new snow at 9k'. Perhaps 10cms in town. Light density.  Minor wind effect. Partly cloudy morning, turning mostly cloudy. Cold temps. Calm to light winds where I was, but lots of snow was being transported off the exposed ridgelines south of town. Quite a bit of cracking of the new snow this morning while breaking trail and while skiing, even though the wind effect was still Fist hardness.  A couple of collapses noted as well in the deeper drifts.

Went into the Lightning/Taylor Creek area of the Southern Madison’s in search of some powder skiing with the new snow. On our ascent toward Woodward Mountain via the backside, we found fresh snow varying from 2 inches at the trailhead to foot deep lightly drifted areas in the upper elevations. In the protected low angle gully we ascended this new snow sat atop either rocks or a very stout wind crust. The latter of which made for great skiing. We descended Woodward top down and assessed the possibility of thin (3”) wind slabs being reactive on the stout wind crust as the Woodward side seemed to have received a lot more loading from the storm’s E winds. As we rolled over to slightly steeper terrain, I noticed the snow stiffening just below my skis and gave it a few hops where I intentionally popped the pictured slab. With this information, we decided to carefully traverse to more protected trees and descend via a less wind loaded and hazardous route. We ski cut from tree to tree triggering a few more of these very small slabs before finding wonderful powder skiing lower on the mountain where the wind had significantly less effect. 

All of the slabs were 1 to 4 inches deep and propagated 5 to 15 feet wide. None of them possessed the mass or were on steep enough terrain to overcome and slide over the stauch wall. Overall was a great lesson in mitigating hazard and we were rewarded with some great turns.
