Chad Kellogg. September 22nd, 1971 to February 14th, 2014. Seattle climbing community legend. Dear friend to many. And the toughest guy around. "For Chad, not eating and shivering on ledges--that was like skiing powder for him. It was just that fun," remembers Jens Holsten. Today, we take a look at what gets left behind when someone like Chad leaves us, and what grows in that vacant space. In part one, we hear from Jens, Chad's climbing partner, good friend and mentee during the final years of his life. In part two, we follow Ras Vaughan and Gavin Woody as they pick up the torch on a project Chad dreamed up, but never completed: the Rainier Infinity Loop. An idea so grand, it seemed almost inhuman.
