He reappears, water streaming from his face, and swims to the end of the pool. Duttweiler grabs a branch and hoists himself out. He's soaked to the skin. But he looks back and admires the graceful sweep of the waterfall, ignoring the water streaming down his legs and the cold. Some canyoneers use breathable dry suits designed for whitewater kayaking. But they are expensive and tear easily. Brennen wears a cheap, lightweight wetsuit shirt; Duttweiler wears fast-drying nylon pants and a synthetic top and shivers to stay warm.
Although area canyons aren't clogged with hordes of canyoneers, several local stalwarts, including Brennen, are busy organizing a canyoneering club. Going alone into a canyon is not recommended; that cost Colorado climber Aron Ralston a hand. Brennen once spent an unplanned night alone in the mountains.
Brennen estimates he's made first descents in the San Gabriels -- exploring canyons with no signs of previous human passage -- at least a dozen times. His website lists more than 50 different local canyon trips.
Brennen finally emerges from the canyon and back onto the Mt. Wilson Trail, greeted by astonished hikers who ask: "Where did you come from?"
