Rock climber Dean Potter and another man died while attempting parachute jumps from a 3,000-foot-high (900-meter) cliff in California's Yosemite National Park, officials said on Monday, the latest in a string of deaths nationwide in the extreme sport of BASE jumping.

The bodies of Potter and a climbing partner, Graham Hunt, were discovered Sunday after a massive search that began at dawn, Yosemite spokesman Scott Gediman said.

They were reported missing Saturday night after jumping with parachutes from a cliff near the park's storied El Capitan and Half Dome rock formations in a type of extreme sport in which climbers leap from fixed points, often bridges or high mountain cliffs.
