Squamish locals Will Stanhope, Paul McSorely and Marc-Andre Leclerc, along with American Matthew Van Biene have summitted a new peak.

Despite a bad season around southern Patagonian peaks such as Fitz Roy and Cerro Torre, northern Patagonia was in great condition in early January 2014.

Canadians Stanhope, McSorely and Leclerc were joined by American Van Biene for the first ascent of Mariposa.

Here is what Van Biene said on his Facebook, “After what was surely one of the most epic weather windows in northern Patagonian history we have returned from what was easily the wildest adventure of my life. Boats, horses, backbreaking loads, bamboo machete hacking bush-crashing through the jungle, multiple sketch tyroleans, gaucho drinking huts, more huge backpack loads, countless river crossings, hiking in rafts to cross a lake to access a big wall and then climbing said big wall, open bivies, coffee, little rest, rafting back out the whole 40 km of truly wild and scenic river. I got to spend my birthday in the mountains with one of the most impressive natural amphitheaters I have ever seen.”

In a correspondence with Gripped, the climbers were enjoying some post-send beers and said it was a perfect trip. We will be updating the story as more details are available.
