There are summer ski turns. And then there’s Jim Ryan and Madison Rose Ostergren’s version of summer skiing. 

Patchy snow in Grand Teton National Park, WY serves as the perfect venue for Jim and Mads to scratch their August skiing itch, with descents of the Grand and Middle Teton. 

But the way these two ski, lightweight touring skis aren’t gonna cut it. Rocketing fast turns down the Middle Teton Glacier is a worthy reward for hauling resort boots and skis 6,000 feet up into the alpine.
