Gib Lewis was one of the Stonemasters, a group of rock climbers and adventurers roughly from 1973 to 1980. They originally climbed in Southern California, principally at Tahquitz, Suicide Rock, and Joshua Tree. Later they climbed at Yosemite. The initial group were those of the first ten ascents of Valhalla on Suicide Rock. The senior member and leader of the informal group was Jim Bridwell. In addition to Jim and Gib, other members included Rick Accomazzo, Dale Bard, Dean Fidelman, Richard Harrison, Mike Graham, Robs Muir, Bill Antel, Jim Hoagland, Tobin Sorenson, John Bachar, Lynn Hill, Ron Kauk and John Long.
