The Four Day Climb, led by Ben Luedtke and Will Ambler, successfully reached the summit early this morning and is now on the descent.

Ben reports cold temperatures accompanied by sustained winds around 30 mph. Route conditions are firm, and skies remain overcast.

Congratulations! 

It was another day full of adventure here in Patagonia! 

After a much needed nights rest the team woke to a beautiful morning, and not wanting to miss an opportunity we hopped aboard a boat and headed over to explore the Grey Glacier located nearby. 

We did a quick refresher of crampons and harnesses before our glacier guides took us out on the ice to explore. Where we walked around many cravasses, took pictures, learned a little about how the glaciers have receded significantly in the last few years and move down slope roughly 80 meters a year. 

We returned to camp after about 4 hours to have lunch and prepare for the 4 hour hike to our next camp. Along the way we watched several condors soar close by and just enjoyed the stunning scenery. 

Everyone is going great and throughly enjoying each day. Although I can tell the fatigue of hiking so many days is starting to build. But this team is tough and have been on many adventures together, so I’m sure they’ll easily rally for the last few days we have here. 

We have officially left the O portion of the trek and have joined many many other trekkers on what’s call the W part.

The clouds started to lift last night and by time we were ready to attempt Chimborazo the sky was completely clear for the first time during our adventure.
We woke at 11 p.m. to start our day and it was virtually perfect for a summit attempt; cool temps, no wind, and a sky full of stars.
The route starts with a rocky traverse but quickly changes to a step snow slope. At 18,000+ feet elevation steep slopes really take their toll, but our team was ready for the challenge. Six hours later, just as the sun was rising, we reached the summit. It was quite cold and a little breezy on top so we watched the sun rise, enjoyed our first real views of the many mountains of the Ecuador skyline, and headed down.
Chimborazo was a challenge but everyone on our team met that challenge with smiles.

The mountains lost a legend this week.

To the climbing community, Jim Whittaker’s impact is immeasurable. To us at RMI and Whittaker Mountaineering, it was foundational.

Jim was Lou’s twin brother, and their shared love of the mountains shaped American alpinism in ways that still echo today.

Rest easy, Jim. We hope you and Lou are climbing something beautiful.

We woke to cold temps around 20 below zero and did our best to stay warm as we emptied our tents, broke them down, and cached anything we wouldn't need for the next few days up high. Over half the route was already familiar as we did our acclimation day two days prior to 16.2k at the top of the fixed lines. Today, we needed to not only get there but an additional 1000 feet of gain while traversing the West Buttress, for which our approach is named.
 
The chilly morning very quickly turned hot as the sun crested the edge of where we set our sights, camp at 17.2k elevation. By the first break we had shed at least a layer and by the second, most of us were in our base layer sun-hoodies for the rest of the hike. We have not seen a clearer day so far on the trip and the bluebird skies made for epic photo ops of not only the Kahiltna Glacier from which we started but the entire valley - about 270 degrees of snowy mountains, rivers, and the snowless flatlands beyond. Once we reached the Buttress we could peer down at the 2000+ foot drop at 14 camp where we had slept the night before.
 
We navigated the fixed lines using our ascenders, sliding up an anchored rope while allowing us to easily not slip back down very steep slopes. We clipped in and out of anchored pickets with caribeners across the snow and the sometimes rocky Buttress spine. We used a mixture of steps - the crossover and duck step to carefully drive our crampons into hard snow and blue ice while balancing with our ice axes. All in all, we did everything needed to safely arrive at our destination.

After chiseling very hard snow and ice to make flat platforms, we pitched tents and settled in to rest our legs, get hydrated, and refuel. The weather tomorrow is forecast to be clear as well with some possibility of moderate winds. If we wake up and the mountain isn't blowing snow we will most likely go, if it's too windy we will rest and go Friday. All of our team is still relatively healthy and in good spirits. We are all super stoked for the great weather forecast and the hard work we have put in to get to this point. Tonight, we settle into freeze dried meals and watch the midnight sun drift across the horizon. Tomorrow, we all hope to summit this great and beautiful mountain.

Today we walked 8 miles from Casa de Piedras to Plaza Argentina Base Camp. I’m happy to report: we all made it in good form - big win! 

Highlights included:

We got the best send-off this morning from Jimmy and Eze, who somehow made gourmet meals deep in the Andes. Truly unclear how they do it, but the food was incredible.

We’re generally feeling… better. After all the travel, trail starts, and adjusting to the high, dry climate, it feels like we’re finally settling into expedition life. Routines are forming. Bodies are cooperating. Spirits are up. A miracle.

We started the day by yelping and laughing through the coldest glacier water imaginable. As we crossed that first river, Denis said, “A core memory was just created.” And despite the numb feet, standing there as the morning light hit the rocks and exploded into colors around us, it really felt true.

We FINALLY saw Aconcagua. Yes — actually saw her. The clouds cleared and there she was: gorgeous, massive, slightly intimidating. We got to stare at her all day, which felt pretty special (and mildly existential).

We played “I Spy a Guanaco” for most of the hike. I don’t know who won because we’re not competitive, but there were many, many guanaco sightings. And we got to hear them relincho. A yipping sound they make and also what the valley we ascended was named after - Relinchos valley.

And… we made it to Base Camp! Our home for the next four days. Tents are up, duffels are everywhere, and everyone suddenly looks like they’ve been living outside for weeks (it’s only been days but don’t tell the team I said that).

By the end of the day, I realized Denis was right — not just about that river crossing, but about the whole day. It really feels like one of those memories we’ll carry for a long time.

Tomorrow is our first rest day and we are very much looking forward to it.

Mexico dispatch 2.27.26

Today we woke way too early, with way too little coffee, to leave our
quaint spot in Puebla to head out for Tlachichuca (or as I  call it "T+10,"
that saves everyone from my terrible spelling and even worse pronunciation)...it's time for the main event, Pico de Orizaba.

We got a great tour of the soap factory turned climbers' hut that's 100+ years old. It was good little history lesson of the Industrial Revolution as well. Who knew climbing was so educational?!

We got one last quick & delicious lunch and fingers crossed we've got all our needed gear for the next ~24 hours. Then 2 hours of hot, bumpy, dusty and smoky fun up to our campsite.

It's been an amazing journey so far with great people and many memories made. From bumpy roads, unique baños, dusty hikes, delicious dinners and everything in between. This trip is definitely one for the books and it's not over yet!

High  camp is a beautiful rocky spot where the clouds envelop us. It's quite nice minus the wildfire smoke. The Refugio was a nice little place to have our dinner after a quick avalanche briefing and hike to get the blood flowing. Next step is up.

I want to take a moment to give a big thank you to all our families and friends back home who are supporting us chasing our dreams in
the mountains.  We couldn't do this without y'all. I hope y'all have enjoyed following us along on this adventure. (And a special hug to my Scoops! I miss you buddy.)

iMuchas Gracias!

P.S. - I just lost the game ;)

Climbers on the Four Day Climb July 15 - 18 reached the summit around 6:30 am today led by RMI Guides Sam Hoffman and Jack Ritterson.  Jack reported a very nice day and a great route but quite windy.  The teams were descending from the crater rim around 7 am.  Once back at Camp Muir they will take a short break before continuing down to Paradise this afternoon.  Their program will conclude at Rainier BaseCamp later today.

Nice work team!

What a day we had here in Chile! 

While technically there isn’t a “summit” day on this trek, today was officially our big day. 

The forecast had us slightly concerned we were going to be hiking all day in rain, but the weather gods were very good to us. We left camp in the dark at 5:40am and made relatively good time up to John Gardner Pass, our high point. Then descend slowly and steeply back down to the elevation of the surrounding lakes. All in all it took the team just under 11hr with breaks to finally arrive in camp for the night. 

To say the views were amazing would be an understatement, and it’s difficult to put into words how truly beautiful this part of the world is with all the mountains, huge glaciers, turquoise lakes, and peaceful forest that we’ve experienced thus far. 

We have just wrapped up another delicious meal and I’m happy to say the whole team is freshly showered too!

We left Riobamba late this morning for our approach to high camp on Chimborazo. One of the great things about climbing in Ecuador is that we can drive to nearly 16,000 ft. From there, it was a two‑hour hike to our new dome‑tent home at 17,500 ft on Chimborazo.

The weather is looking good, so we’re heading to bed early in anticipation of an early wake‑up to climb our third—and biggest—volcano of the trip.

Wish us luck!
