“How cold was it?” is the logical question to ask a climber of Mt. Everest. However the correct question may just as often be “how hot was it?” That is certainly the case for climbers in the Western Cwm.

The Western Cwm runs from the top of the Khumbu Icefall at 20,000 ft to the bottom of the Lhotse Face at 22,300 ft. Cwm is a Welsh term for a bowl shaped valley. The Western Cwm can be thought of as a lazy river of ice and snow that is marked by huge lateral crevasses that guard entrance to the upper sections of Everest and Lhotse. Camp 1 is basically located at the bottom of the Western Cwm and Camp 2 near the top. The Western Cwm was named by George Mallory in 1921.

The Western Cwm is also know as the Valley of Silence because it is windless and therefore extremely quiet.  Despite its relatively gentle slope, it can be one of the most difficult sections on the route.

The best way to understand why the Western Cwm can be so punishing is to reference the water boiling systems that are ubiquitous in the Khumbu Valley. Look carefully in the image above and you will see a tea pot set inside a solar refractory. On a bright day it doesn’t take long for the reflected solar energy to boil water. If you imagine the Western Cwm as a solar refractory with reflective glaciers all around, then the climber is a tea pot. It can be brutal.

I was in the Western Cwm for four days on the first rotation and fortunately the weather was such that I didn’t become a tea pot. Instead, I enjoyed some fun technical climbing without all of the drama of the Khumbu Icefall. There was vertical ice climbing, ladder crossings and rappelling, all in a casual and unhurried pace as we worked up and down the Western Cwm acclimatizing to the higher altitudes and then ultimately in our move to Camp 2.

Equally enjoyable was the opportunity to so clearly see the climbing route to the summit of Mt. Everest. It was the first opportunity to feel like I was building a relationship with the mountain and studying the route in a way that wasn’t hypothetical.

It’s not often that I will wish for cloudy and cold weather, but it will certainly be the case for my return visits to the Western Cwm.

Thanks for following along.

    After discussing your effort…A friend of mine sent me this fabulous link from the Discovery channel that provides an interesting visualization of the challenge Jim is facing on this climb…Touching on the avalanche/accident in ’14…
    Not exactly sure how this film was made…because the air is so thin at the top…helicopters cannot reach the summit. Drones?

    Jim…Savor every minute of the climb!…we are all enjoying vicariously

    Continued good luck …Onward and Upward!

    Utterly unexpected post today. This mountain has such a wacky, playful, and creatively defensive personality. What will she throw at you next?

      Staci, what a wonderful way to describe the mountain dynamics. It is always something it seems. Thanks for your note! Jim
