Aconcagua Day 4: Trek to Casa de Piedra

Posted on February 9, 2025August 5, 2025 by Backcountry Fever

DAY 4 – Trek to Casa de Piedra

DAY 4 was another pretty chill day.  Our guides were really good at helping us conserve energy by always slowing us down.  The pace was so laid-back.

By the way, this 360° Traverse is waaaay more interesting than the standard route–more on that later.

Here’s looking back at where we just came from. You can see our last camp off in the distance (circled).

Temperatures were much more pleasant today.

The mules seen crossing the river here are helping us get the bulk of our gear to base camp — after that, it’s up to us to carry our own stuff the rest of the way (or hire a porter to do so).

Our next lower camp comes into view, Casa de Piedra off in the distance.

Here we get our first glimpse at this mighty giant.  While seeing this at 10,600′, we still have a long way to reach that 22,800′ summit!

Along the banks of Rio de las Vacas, Casa de Piedra is “home” for tonight.

Casa de Piedra

Today’s stats: 10 more miles and another 1,500 feet, but this time with a nice breeze in the 80s.

Side Quest

We arrived here so early, I decided to wander around above camp.  Continuing up to 11,300′, I ran into what a thought was a wild llama.  Turns out this is a guanaco, which is in the llama family but bigger. It’s also a puma’s primary source of food.

I also found the source of our drinking water.  What blew me away was how none of this water was filtered before we drank it yet no one got sick from it either.  …and there was plenty of opportunity for this water to be tainted between all the free-roaming mules and wild guanaco’s running around.

I didn’t think I’d go far enough to start my watch or record my tracks with my phone, but my Oura ring picked up another mile.

The rest of the day was spent relaxing since tomorrow, we would cross the Vacas River and head up Relincho Canyon across the way.

Case de Piedre is the last of lower camps before reaching basecamp.

My 13th time on this summit, but 1st to enjoy some watermelon at the top 🍉 Thanks to Jocelyn, the "Watermelon Girl", who lugged that all the way up and was gracious enough to share it 😁

Veered right a bit of the South saddle (red line) for a more adventurous route up to Timp... but once we got up on the ridge, we saw we could have done an even more interesting way (yellow line) cutting into that cliff band and zigzagging along the shelves as seen in the 4th picture (taken from South Timp).

Only a few patches of snow remain between Aspen Grove and Emerald Lake.

For those interested in doing Deseret Peak... the snow is still in the couloirs, but only for a little while longer!

The best way to slide down a snowy slope in Spring conditions is like this...

Didn`t get much mountaineering in this Spring, so trying to catch the last bit of something before the snow`s all gone.

Bagged Bierstadt today! Thought I could get Evans too, but took one look at The Sawtooth and went "nope"! I was also by myself... either way, that stretch looked intense even without the snow.
