Dec 9, 2011, Rainier, Muir and Nisqually Chute CORN

Well, I finally found the corn on Rainier that had escaped me on my last trip up to Muir 3 days earlier: on Friday late-afternoon, Nisqually Chute was covered top-to-bottom in nicely softened, smooth, stable, untracked corn. I skied the entire main Chute in a nonstop 1500 vertical-foot shot, undistracted by partners or taking photos, just me and the sun and snow and solitude. A totally breathtaking run, with an uncommon feeling of isolation and remoteness due to the absence of any other people or any previous ski tracks in the entire Nisqually Glacier basin. I was totally buzzed and stoked at the bottom. Followed by a short skin up to watch another mountain sunset from Glacier Vista, then a twilight ski back to Paradise with the full moon rising to the east. What a spectacular day!

And then the thought hit me: Nisqually Chute! It was so obvious: a nice 40° steep S and SW facing chute that would catch the maximum possible insolation from the low December sun, and was almost certain to be corned up. I couldn't believe that I hadn't thought of it yet, nor that I hadn't actually gone and skied it already this week, like on Tuesday when I'd been to Muir and skied frozen icy crust for much of the run -- I should have dropped down the Chute that day! I looked through my photos from Tuesday, and the few that viewed the Chute showed adequate snow coverage, a bit thin and rocky at the entrance, but totally skiable and looking quite good down the main part of the run.

So that would be the plan by default for Friday: head to Paradise at a leisurely hour, and take a look at Nisqually Chute in the afternoon. The UW model predicted a period of near-calm (5-10 knots or less) winds at 10000 ft from Friday morning through late-afternoon, as the dome of high-pressure shifted east from the Pacific and directly over Oregon, along with freezing levels over 10000 ft. So that would be the window to try for corn.

An 8:30am departure from Seattle had me skinning up from Paradise just after 11am, with temps already a toasty 48 °F in the parking lot. The late start was perfect for skinning on properly softened snow instead of frozen crust. To avoid the problems of skinning up the still-firm Pan Face, I put in a skin track up the SW Ridge of Panorama Point, and found ideal skinning conditions with 3-4" of ski penetration on this south-facing slope, allowing me to set a solid track up the steep ridge with no risk of sluffing or sliding.

On the rolls above Pan Point and above Pebble Creek, portions of my skin track from Tuesday were still easily recognizable (wherever the snow had been soft enough to actually leave a track!) -- clearly not much skier traffic up here this week. There was an occasional easterly breeze at Paradise and as high as Pan Point (due to easterly pass flow), but above Pebble Creek the air became very still and quiet with only the lightest wisp of wind every so often. The lack of wind, strong sunshine, and warm temps were finally allowing much of the Muir Snowfield to soften slightly. It wasn't corn, but the icy crust was semi-softened and skinnable, as were the large areas of windpack -- all noticeably softer than the solidly frozen state on Tuesday, despite Tuesday's higher 11000 ft freezing level.

My skin track from 3 days earlier on one of the rolls above Pebble Creek, no one else had skinned up here since then.
I skinned up along the west edge of the Snowfield, to stay on areas with the most southwesterly exposure and thus maximum afternoon sun. These aspects had actually softened somewhat all the way up to 10000 ft this day, right to Camp Muir. However, there were still many icy patches with clear water ice, and I put the ski crampons on above 8700 ft for greater efficiency, but someone with mad skinning skills could have have probably made it without them.

I never intended to go all the way to Muir today, because of the icy crust I had encountered on Tuesday above 8500 ft. But as I passed the elevation of the entrance to Nisqually Chute at 8400 ft, I realized that I had to keep going up. It was only 1:15pm, and the weather was just too nice to not continue on to Muir, even if the skiing above was poor. I figured I'd be back to the Chute by around 3pm, which would be the ideal time to get the maximum softening of the snow. Saw 4 other skiers descending the Snowfield (including one carrying their skis down) as I continued skinning up, but no one was heading for the Chute.

Reached Muir at 2:30pm, all other skiers and hikers and last night's summit attempters (who turned around near 12000 ft on DC/ID) were long gone, leaving behind only quiet and solitude. Since the winds were nearly calm, I made a quick check of the Muir webcam and NWAC instrument tower (it was too gusty to want to do so the previous 3 times I'd been to Muir in the last 11 days). As expected, the webcam and the instrument tower are entirely free of ice and rime. The webcam appears to be undamaged externally, and all cabling appears to be intact, so it is unclear why it has been offline since shortly after 3:17pm on November 20 -- this 20-day outage is the longest since the camera was installed in May.

Skied down just before 3pm, finding the ski conditions to still be quite poor above 9500 ft, still very firm and chattery despite the slight softening. Below 9500 ft, followed fingers of windpacked powder atop the crust as on previous days, all the way to the entrance of the Chute.

And there it finally was, on the open slope just above the entrance: real smooth CORN! This entire south-facing slope at 8500 ft had corned up, and that erased my doubts: the Chute just had to be good corn too.

Looking down from the rocky entrance to Nisqually Chute at 8400 ft, with the Nisqually Glacier and its moraine far below.
Traversed into the Chute carefully through the numerous exposed and partially-hidden rocks at the 8400 ft entrance, made a couple of test turns, and then knew for sure that it was golden: 3-4" of softened corn on a firmer base, actually softened way more than necessary, but well-bonded and not sluffing at all. An old avalanche crown about 1-2 ft high crossed most of the width of the Chute just below the entrance, but stability was not an issue now given the recent weather and very low avalanche hazard.

Looking down the clean smooth corn of the Chute from just below the avalanche crown, with a lobe of old avalanche debris visible far below deposited onto the Nisqually Glacier.
So it was time to let loose and ski the whole Chute in a single shot -- a minute later I was at 6800 ft where the chute becomes a half-pipe, and where the number of fallen rocks studding the snow increases to the point of annoyance, so I popped out onto the shoulder to skier's left. More nice corn turns down the sunny shoulder to where it flattens near 6400 ft, and the corn disappeared to be replaced by heavy windpacked powder, but luckily not crusty at all. I was totally stoked to have enjoyed an awesome run, in sweet May-like corn conditions but with the total solitude of December.

Looking back at my ski tracks in Nisqually Chute and the shoulder below it, a zoomed view from atop Nisqually Moraine.
A quick schuss down the trough beside the moraine brought me to the base of the 200 ft reascent back out to Glacier Vista. No need to rush this, as I wanted to watch the sunset from atop Glacier Vista. A leisurely skin back up, breaking trail up through a foot of heavy powder on this westerly aspect, then thinning to exposed icy crust for the last 50 ft at the top, which convinced me to put the ski crampons back on. Arrived atop the Vista at 4pm, and enjoyed watching the sunset for the next half-hour.


Then a twilight cruise down the crusty snow back to Paradise, enhanced by the full moon rising in the east as I neared the parking lot -- remarkably it was still 49 °F at Paradise a half-hour after sunset as 5pm neared. A perfect end to an exceptional day, with an unexpectedly great run down one of the best ski descent lines in the Paradise vicinity. I've skied Nisqually Chute numerous times before, but this late-afternoon December descent on untracked corn in total solitude has to be among the most memorable.

Postscript: Looking at the telemetry from Paradise and Muir pasted below, it is clear that the window for skiing nice corn was very short this time. Increasing SW winds hit Muir by 4pm Friday, becoming strong in the evening and overnight, and temperatures fell by several degrees. If these strong winds and falling temps had arrived 4-6 hours earlier, Nisqually Chute might have stayed frozen and crusty all day.
As for Thursday Dec 8, the temps were about 3-5 degrees cooler at Muir and 6-8 degrees cooler at Paradise than on Friday, with winds at Muir during the critical 10am-3pm period being slightly stronger too. Not certain if the Chute would have softened under those conditions, but based on how soft it was at 3pm Friday, I think it would have been nicely skiable on Thursday too.

As for Thursday Dec 8, the temps were about 3-5 degrees cooler at Muir and 6-8 degrees cooler at Paradise than on Friday, with winds at Muir during the critical 10am-3pm period being slightly stronger too. Not certain if the Chute would have softened under those conditions, but based on how soft it was at 3pm Friday, I think it would have been nicely skiable on Thursday too.

Thanks, Amar.
Thanks, Amar.
Fantastic report..way to dial it all in.
Great TR and route selection. ;)
Not sure how accurate this is, but sounds like the Muir cam is fogged internally?
