Joseph M. Miller Jr., a 38-year-old climber from Lafayette, Colorado, was killed in Eldorado Canyon State Park

Mr. Miller, climbing on an almost new 9.7mm Beal rope, began "having difficulty with the climbing near the point where the third piece was placed and was being encouraged by the belayer." And then he fell. His highest piece of gear, the #0.5 Camalot, pulled out of the rock when his weight came on the rope and cam. He continued to fall, past a small ledge and over a slight overhang, when his rope broke. He continued falling another 80 feet to the ground.

A 20-year-old Alabama man fell about 100 feet to his death Wednesday at Ravens Roost Overlook along the Blue Ridge Parkway.

“It looks like some kind of equipment failure,” he said.

Sullivan and two Farmville men had been climbing the rocks at the overlook since 11:30 a.m. Friend and fellow climber Drue White, 21, said he believes a rope broke during the sixth and anticipated final climb.
