For Sarah Strattan ’11, life revolves around mountains—climbing them, skiing them, and photographing them.

Sarah Strattan ’11 grew up in Evergreen, Colo., fascinated by the “Fourteeners”—the Colorado peaks that exceed 14,000 feet. In college, Puget Sound Outdoors introduced her to backpacking, and an outdoor leadership experience in Alaska taught her about mountaineering. She climbed Rainier, then Denali. Then she set her sights on the Himalayas. Strattan, who taught middle school science for a time and now works on the ski patrol at Aspen Highlands Ski Area, spends part of each summer challenging herself on Asia’s tallest peaks. Last year she summited K2, the world’s second highest mountain; this June she’ll head to Pakistan to climb Nanga Parbat. Here are a few of our favorite images from her travels.
