PRE-TRIP

November has been a miraculous month thus far for skiing; typically, November is dark, dry, and sad, and skiers get overly excited and head out into “sharky” (i.e. rock-infested) terrain.NOT THIS YEAR!

Last week Dan, Michael, Tessa, and I had explored Bullion Basin and the powder had delivered…with NO SHARK ATTACKS! The snow was so good I had to go back, and with high pressure in the forecast for Saturday and Sunday it would be…sunny? WHAT A CONCEPT!

Dan, Madelynn, Kyle, and I had drawn out some routes on Caltopo in the Cement Basin and Lake Basin regions near East Peak, and we were excited to go out and explore further than Bullion Basin.

TRIP REPORT

We met up in the Upper C parking lot at 7:30 AM and were able to slap on skins at the cars. We took the snowshoe trails into Bullion Basin, following Ted’s Trail switching back and forth at a low grade. Once we reached Bullion Basin we followed a skin track heading up towards Platinum Peak, climbing up the SW face of Platinum to then ski down into Cement Basin. The skin track was icy from a rain crust that had formed from days prior; needless to say, there was slipping and sliding at points.

 

Following a skin track heading up towards Platinum Peak. The skin track was tracked out and icy.Half-way up the skin track I turned around and…MT RAINIER! In full view…amazing.

What a mountain! Need to go and ski that thing…Blue skies in November sure was a treat. We continued up towards Platinum Peak, where we transitioned for the first time and prepared to ski down into Cement Basin.

Heading up the skin track towards Platinum Peak, with the sun poking out through the trees.

Looking out over the Norse Peak wilderness…with Mt. Adams poking into view in the horizon.The top of Platinum Peak was our first transition point for the day, and we planned to ski down into Cement Basin to then skin up towards the Lake Basin chutes. We were giddy and excited for the north-facing aspect off of Platinum Peak, as the snow appeared dry and stable. The turns were going to be good!

The smile says it all…winter is here!And good they were! Kyle ripped down the slope, shredding on lightweight skis made by Peter Butler, a local skimaker. Towards the bottom we slapped on our skins and headed up towards the Lake Basin chutes, a series of narrow couloirs that face north towards Basin Lake. We had scouted them out on Caltopo, and Dan had even read about them in a local guide book. They sounded narrow, steep, and a whole lot of fun.We followed the drainage north up from Cement Basin to a low saddle, then followed Kyle as he cut skin track up the ridge to the NE towards the ridgeline above Basin Lake.

Skiing off the NE face of Platinum Peak towards Cement Basin, then skinning up towards the Lake Basin chutes.

Looking back at the NE face of Platinum Peak…a few of those squiggles were ours!From the top of the ridgeline above the chutes we began to look down. It had been a few months since I stared down a couloir…but the memory came back. Looking at the choke, analyzing the moves…it all fell into sequence again.

Right or left?We took a look at three different couloirs…looking down it was hard to assess which ones were fully “in” in terms of snow coverage. Rocks were clearly protruding in places, but we could see ways to ski around them. Eventually we picked our line, and as expected, Kyle led the way down, sluffing off the top layer as we kept eyes on his tracks. There was around 4-6″ of top layer snow on a firm rain crust, which sluffed off pretty easily, but overall the stability was solid. The layers appeared well-bonded and “right-side up”, meaning the crust was below the top layer of lighter snow.

Dan peering over the edge down our couloir of choice.There was a flat bench with a large tree around halfway down the couloir where we agreed to meet back up as our first “safety spot.” After Kyle’s initial turns I followed suit and headed down towards him. Sluff management was key, i.e. giving time for the snow kicked off to slide past before turning back into the slope.

Looking up at the first half of the couloir. We skied to climber’s right, i.e. the right side of the image.The choke (i.e. the narrowest part of the couloir) was next, and again Kyle led the way, straight lining through it before making a turn. The choke was just wide enough to fit through sideways, which was my method of getting through (Kyle charges harder than I do).

Kyle charging through the choke. I opted to side-slip through, not as brave I guess.We continued on down through the couloir, which opened up into a wider apron further down towards the lake. The snow quality was quite variable, turning from light power to thick, heavy snow, to avalanche debris that was very garbage-y.

Kyle continuing on down as the couloir begins to open up.Once we were all down, we headed back up to the saddle above Cement Basin, where we had skinned up to previously. This time, however, we opted to skin up west towards an unnamed point above Upper Lake Basin, where a north-facing bowl held great cold snow. As Kyle put it, “we skied a great line..now time to ski great snow.”

We tracked back up from Basin Lake to the low-angle ridgeline above the upper basin, just south of Scout Pass.We took a few laps on the upper basin, circling back to the unnamed point and dropping back down into the northern facing bowl.

Madelynn ripping some fresh snow on the northern bown in the upper basin below the unnamed point.We took two laps in the upper bowl before south towards East Peak, where we took another lap in good northern facing powder.

Such sensuous curves!Around 2:30 PM we began to head back towards the cars; from East Peak, we skied SW again towards Bullion Pasin, aiming for Ted’s Trail where we had skinned up. The southern slopes were much more sun affected than the northern slopes; by the end of the day the snow was wet, heavy, and chunky.

The saddle between East Peak and Platinum Peak was a good spot to transition to ski down.Eventually we met back up with the skin track and skated our way back down to the car along the snowshoe trails leading up to Bullion Basin. Overall, a great day in November with amazing snow!

Thank you for a wonderful trip report.😀


That's a tr that makes mine look so small.   Great photos and prose.   Well done.   If you ever want to check out the Hogback cordillera of the Goats Rocks Wilderness accessed from White Pass I will guide you.


When a friend & I discovered that backside full of couloirs 35 years ago it was something special and given the heavy touring equipment at the time, a hard day. It's been mentioned but one time I know of & the avy run-outs tell you it's potential on a bad day. Once, a herd of mtn. goats ran up the ridge to maybe 50 feet before they saw us & retreated. After the laughter died, did a ski cut, thought it safe and a final jump sent the hill. Good on your team for pulling this off.


Great TR. Thank you

Which mapping software did you pull those maps from?


Great TR! Skied a couple of these yesterday. Such a beautiful area. Those icy volcanic cliffs are pretty unique - haven't seen anything like that in Washington before. Reminds me of Hyalite.

Also, for the exit, we started skiing W from the peak N of East Peak and gradually traversed S skiing a good bit of fall line. Intersected the road at the northernmost switchback at about 5,000'. Found some great preserved powder here - best snow of the day. Good option for the sunny days to avoid skiing a steep SW aspect in the afternoon.
