This episode is all about Tirich Mir in Pakistan’s High Hindu Kush. This past summer, two Japanese climbers completed an ascent of the secretive north face of this 7,708-meter mountain—an isolated wall that probably had never been attempted before. For the last decade, Kazuya Hiraide and Kenro Nakajima have formed one of the most successful partnerships in the world for lightweight, alpine-style new routes on high 7,000-meter peaks. Kazuya had dreamed of climbing Tirich Mir for more than 20 years, and the route they pieced together was a creative and committing solution to a very complex mountaineering problem. We'll also hear about their next goal: an audacious attempt on an alpine-style ascent of K2's west face.

To introduce Tirich Mir and its long history, we spoke with AAJ senior editor Lindsay Griffin, an expert in the climbing history of the Greater Ranges. Among other things, we learn why a member of the first ascent party carried a huge rock to the summit!
