BUENA VISTA, Colo. (AP) -- A man climbing Colorado's Mount Princeton has died after falling about 140 feet.
The Chaffee County Sheriff's Office says 31-year-old Matthew Wayne Lackey of Boulder was climbing a rock face with other people on Monday afternoon when a large boulder he was holding onto came loose, causing him to lose his balance.
He fell about 40 feet to the ground below and then fell another 100 feet down a rocky slope on the mountain, which rises over 14,000 feet.
The sheriff's office says Lackey and his companions were not using any climbing equipment.
A medical helicopter was called to the area but Lackey was pronounced dead at the scene.
On Tuesday, Boulder restaurant Arcana posted to Facebook that Lackey had been its opening chef and offered its condolences.
