 Atlantic`s West Ridge- The Partial Pillage  

This is one of those times of year when everything is constantly changing in the mountains. Avalanche conditions, and weather get forecasted, but there is just no way to really know without going and taking a look... within reason. When we left the forecast called for -20 windchills and considerable avi danger.

We had planned on staying on a relatively avi safe ridge route up Pacific's West Ridge, but decided to change plans at the last minute, and headed for Atlantic's West Ridge. The route made sense. With the avalanche danger sitting solidly at 'considerable' above treeline, the route would permit us to stay below treeline all the way to the ridge, were we would be able to fins a safe way to gain the ridge line.

Excited to get out first winter climb of the year, we left the snowshoes in the car, strapped on avi beacons and headed into the cold morning.

The trail up the road was very well packed, as was the route through the willows as we crossed the Valley to start up to Atlantic's ridge. The trail continued to be well packed until we reached treeline. At that point, the reason for the CAIC's forecast became obvious. There was a 8-12" slab sitting on top of powder. Plunging our trekking poles into the snow for a quick layer test told us that there were at least 2 slabs beneath our feet, so we carefully found our way up the slope, finding avalanche debris from at least one small slide still below the Saddle.

Let the post holing begin!

When we reached the saddle, the route up to the ridge was obvious. We would be able to stick to rock and shallow snow, but as we looked around, we could see recent slide paths all around us, dominantly on Mayflower Hill. Excited to be on the ridge, I made the mistake of making the comment that the only thing that would turn us around now would be for us to give up. Both Jesse and I felt really good, with the exception of my very cold feet, so we took a quick break and took to moving up the ridge. As we looked back we could see what had been a large avalanche running from the Northern aspect of the West Ridge into the bowl below. Another reminder of the unstable conditions.

The snow on the ridge remained unconsolidated, so we tried our best to stay on rock whenever possible, but crossing the "knife edges" of snow meant punching through what were the very tops of slabs, as the sound of avalanche blasting in the Breckenridge area cut through the quite, and nearly windless day. Again, we were encouraged, because as long as we stayed on the ridge, we would be above the danger that was so clearly below us.

This lasted until we reached approximately 13,450ft. At this point, we came up on the cornise that has garnered a good amount of attention on a thread on this site. The best way across, that would avoid the cornise and keep us above rock, but near the ridge crest would require that we cross the very top of what was a very wind loaded slope, that had formed an obvious convex form. As I carefully stepped onto the slope, I immediately post holed to my knee. Hoping this was the result of the heat from the surrounding rock, I opted to try a couple of more steps, but it only seemed to get worse, with a large slab sitting on top of powder. Jesse, hoping that he could find a way was able to make it across, but our weight difference was just enough that no matter where I tried, even going up onto the area that was clearly the beginning of the corise netted the same result for me.

I am very conservative when it comes to avalanches. I never go out without a beacon, shovel and probe, but I do so planning on never having to use them, and believe pretty firmly in traveling through avalanche terrain as though I had no avalanche safety equipment to help. I find this keeps me aware. I was certain that I could posthole my way across a 200ft stretch of avalanche slope with really bad run out. But if I did this, I would be creating a trench across a wind loaded and unstable snowpack. Aside from all else, the sun was now up, and it would not be long before it was on that aspect. If we made it across safely going up, in and hour or more when we came back across, would it be safe then? The benefit of my post holing was that it created a pit through the snow, and the large slab, nearly identical to the ones we had seen in the small slide areas at treeline was intact on this slope, and it was unbonded to the much weaker layer that was supporting it.

My earlier, and rash comment about only turning around if we "gave up" was heavy in my head and heart as I told Jesse that crossing this slope was just not safe, and that I felt as though this was a game changer for me. He carefully came back across the slope, and we discussed what my though process was, and headed down a little more then 400ft below our objective.

We were able to make our way down fairly quickly, and as we came back to the saddle, I began to feel my toes that I had forgotten about burn as they thawed out. The decision to turn around started to re-enforce itself as I realized that while I could feel most of my toes on my right foot, my big toe was still numb, with a mild burning sensation. We made our way to the car, and when I took off my boot, I was happy to find that my toe did not look bad, just bright red, and still numb and burning. Turns out I got a very solid case of frost nip, verging on superficial frost bite. Had we kept moving up, my foot would have stayed cold longer, which would have made that a worse situation. The way things turned out, we had a beautiful climb in the mountains, up a cool ridge, got some interesting photos and got to test our avi knowledge. Overall it was a great day, and as always a learning experience.

The pic of Fletcher is just plain awesome, thanks for the TR guys.


Great Photos...

Looks like you guys had a good day, regardless of turning before the summit. If either of you plan on trying Atlantic again later this winter and dont mind another partner, let me know...this one is on my list. Thanks for posting.


nice job guys!

Looks good Trevor. We‘ll have to get out sometime!

That mountain you wanted to know the name of is Jacque Peak. Looks like a nice climb.


it was

a great day! I am going to be adding more photos over the next couple of days. You gave me so many really great ones that display the route wonderfully, that between the two of use we could probably have a 60+ photo trip report


Picture Perfect....

That might have been the most photogenic day all year, I took 203 pictures. Yours of the clouds over Fletcher is sweet, the color is awesome. Here is a link to my photobucket with my favorite pics from the day;

Thanks for posting this, well told.


Well done!!

LOVE the Fletcher pic (#15)
Looks like you guys had a great - and safe - day.
That is a gorgeous area - thanks for posting!
I've had a few "DNF's" in the past month or two - but they've been some of the best days I've had outdoors. I'm learning the summit isn't the only objective on my days out, particularly in winter.
Hope to see more TR's this winter
Keep 'em comin'!

James C

Good Decision

We climbed the west ridge on the 28th, did you notice any tracks that traversed below the slab and stayed on the rocks? It was definitely a hairy climb after that point. On the descent, we stayed to the ridge proper, and traversed that part on our bellies. It definitely seemed like no one really had traveled beyond that point


all at once...

@ stlouishiker - I got your PM too, thanks! I looked it up and it does look like a fun ridge run

@ astrobassman - I know I will be doing thie ridge again before the winter is over, I‘ll shoot you a PM when I‘m planning it

@ benners - thanks!

@ Johnba - we definitely do

@ sunny1 - you know a bad day in the mountain is better then the best day on the couch better to be safe then sorry, I have promised my wife and myself not to get buried in an av i so Im pretty conservative

@ James C - congrats on making it up. I did not see tracks, but there was a bit of a crack down low. So did you guys drop all the way below the slab to where it thins back out and then climb back up? I think I would have had to do something similar to amy crawling it to get across without creating an enormous destabilizing trench up high on the slab. I dont know if you saw the area I tried to cross... the place where it looked like an animal wallowed in the snow Or did it fill in overnight?


Nice pics

Looked like a beautiful day to get out and a good decision (though disappointing, I‘m sure) to turn around. I know how that feels. We live to climb another day and we prefer to keep all our digits too! Can‘t complain about the scenery though!
