Mission Traverse on skis V.3

A Mission traverse from East St. Mary to Sheepshead was a primary goal for this ski season, so with support from Leah and a good forecast, I headed out on a Monday evening to drop a bike and set up for a post ski shuttle before settling in for the night at the St. Mary trailhead.

My alarm didn't go off, but I was still walking by 4:15, and respectably high by sunrise.  I took my time and dealt with surprisingly cold temperatures on the long climb to the alpine.  Although new snow was disconcertingly deep and slabby, the wind didn't pick up at all in the alpine, and I summited ESM in 3.5 hours, cautiously optimistic that conditions would come together.  There were crowns everywhere, but fortunately most of them were old, and new snow seemed to have just stabilized enough following a small natural cycle over the weekend.

I schussed down the Northeast ridge of East St. Mary and transitioned quickly for the long climb to Mountaineer.  The climb to the peak South of Mountaineer went smoothly.  The alpine winds had abated, and it was turning into a beautiful, crisp morning.  I botched the route around the peak South of Mountaineer, but quickly corrected and was on the summit of Mountaineer about 7 hours in.

I like to make a big detour to the East to avoid rick steps on the Southeast ridge.

On Mountaineer.  I skied off to looker's right, climbed the sunlight face below the Garden Wall,
then traversed near just below the Shoemaker/Glacier connecting ridge to the summit of Glacier peak.

My concerns about slabs on the East face of Mountaineer were unfounded.  It skied great top to bottom, and I was able to traverse efficiently below the Garden wall to a nice warm transition break.  The climb to the Garden wall was quick on perfect sticky corn snow.  I put crampons on below the summit of Shoemaker and traversed below the crest to Glacier.  I bypassed the rime steps on the East ridge of Glacier, but the snow climbing was so steep and scary that I think it was more difficult than just committing to the ridge.  Nevertheless, I took my time, kicked secure steps, and was on the summit soon enough.  I skied good snow the upper West face of Glacier peak before making the devious sneak to Icefloe lake through the Glacier/Sonielem saddle, above Lake of the Clouds, and down a sneak gully.  I took another long transition to refuel and psyche up for the push to McDonald.

Good skiing on Mountaineer peak.

I pushed the pace as much as reasonable given my moderately fatigued state on the big climb, and summited in good time.  It was so good to be back on top of this magnificent peak.  The forecast afternoon showers were building, but fortunately they were light and intermittent, and I had striking views to the great Mission valley below.  The Northwest face skied quite well as it always does.  One last push was sufficient to summit Sheepshead.  I was tired, but benefitted tremendously from sticking to a restrained pace all day. I quickly transitioned for a run down the upper Southwest face.  My intended route was to ski the upper couloir, then traverse high to the Northwest ridge.  Unfortunately, I got completely stymied finding a way across the prominent looker's left gully, and ended up skiing down several hundred feet looking for a way in.  I couldn't find anything, so I pounded a gel, skinned up, and climbed along the edge of the gully until I was able to whippet hack my way through a cornice and gain access to the gully.  Whew.

Fun powder low on McDonald.

From there, it was a quick schuss to snow line, and a easy bushwack by Mission standards to the road and out to the bike.  11.6 vertical feet, done in 13.5 hours at a responsible all day pace. The bike shuttle took about 75 minutes, and ended up being an enjoyable way to unwind from such an amazing day in the mountains.  And, best of all, I made it in time to spend an hour with my son before bed time.

Thoughts
The Mission traverse is so good!  For suitors, the route is long, complex, and committing, and it is advised to at a minimum have a good handle on the approach, egress, and a good concept of the route.  The traverse demands the full range of skills, including steep climbing and skiing, and a cagey eye for hazards, especially cornices.  I wrote a brief route description in the Missions route page, with both this route, and what I think would be a simplified "standard route".
