Will Brommelsiek opted to do a five-day traverse with a 34-liter pack to optimize his experience on the single line we rode from base camp on the final day.

The black box over his left hip is one of the recording units we used to learn more about the Yosemite toad. Photo: Connor Wood YOSEMITE TOADS 055
