Our guest for this episode is Leo Houlding, one of the great expedition leaders of our time. Leo's goal for this year was a new free route on Roraima, a legendary mountain in South America that is steeped in British climbing lore. In 1973, a team of four Brits—Mo Anthoine, Joe Brown, Hamish MacInnes, and Don Whillans—made the first ascent of the super-isolated and dramatic north prow of Roraima. Just getting to the mountain involves a lengthy jungle trek and thousands of feet of climbing through a "slime forest." AAJ editor Chris Kalman spoke with Leo about the soggy approach, the wild 14-pitch climb they found, and helping two local Amerindians, Edward James and Troy Henry, become the first Guyanese to climb their country's most spectacular cliff.
