After Brette Harrington's partner, Marc-André Leclerc, disappeared during a climb on Mendenhall Tower in Alaska in March, along with Ryan Johnson, Brette felt compelled to return to the Juneau Icefield in southeast Alaska repeatedly last summer and climbed numerous new routes in the Mendenhall Towers and elsewhere. In September, she and Gabe Hayden completed a difficult first ascent on the rarely climbed Devil's Paw. In this episode, Brette talks with Chris Kalman about this new route and also how her climbs above the Juneau Icefield have helped her through such a difficult time.

In February, Matteo Della Bordella from Italy and Silvan Schüpbach from Switzerland did the first ascent of a very remote peak in Patagonia. But what made their adventure truly exceptional was their "fair means" style, paddling sea kayaks for 100 kilometers to and from base camp, carrying all the food, expedition, and climbing gear for up to a month in the mountains. The AAJ's Chris Kalman spoke to both of them to get the story, including their close call with a tsunami!

Marc-André Leclerc died tragically in a climbing accident in Alaska in March, along with Ryan Johnson. Eighteen months earlier, AAJ associate editor Chris Kalman had recorded a long interview with the young Canadian, in preparation for an article that appeared in AAJ 2017. To honor Marc's life and provide a window into his unique character and intelligence, we offer this edited version of the interview, covering his thoughts about bold climbs from Canada to Patagonia.

You can find the 2017 AAJ article covering these ascents here: http://publications.americanalpineclub.org/articles/13201214332/Two-Climbs-Alone.

Jim Donini first climbed in Patagonia way back in 1974, and in 1976 he made the first ascent of Torre Egger. Now nearly 75 years old, he's still at it, exploring the wild mountains near his summer home on the shores of Lago General Carrera in Chile. Just back from another Patagonia season, during which he bagged yet another unclimbed peak, Jim spoke with AAJ editor Andy Anderson about the beautiful Aysén region of Patagonia, the peaks he's climbed, and his passion for exploration.

Swiss climber Stephan Siegrist has visited the Kishtwar area of India five times in the past seven years, making numerous first ascents. In late 2017, he returned to India with Thomas Huber and Julian Zanker to climb a direct new route up Cerro Kishtwar, an extremely difficult mountain that he had already climbed once before!
