A Jackson mountain biker went to the hospital after being rescued Friday afternoon from the Cache Creek area.

Teton County Search and Rescue volunteers retrieved Derek Collins, 38, after a crash on the Ferrin Trail.

He sustained “substantial injuries,” in the accident, rescue coordinator Tim Ciocarlan said.

At press time, St. John’s Medical Center staff were assessing Collins’ condition, hospital spokeswoman Karen Connelly said. Staff intended to admit him to the primary care unit, meaning his condition was not so serious as to require intensive care, she said.

Neither Ciocarlan nor Connelly would release details of Collins’ injuries. He was conscious and in considerable pain at the scene, Ciocarlan said.

Search and Rescue received a report of the crash between noon and 1 p.m., and 18 rescuers responded.

Collins crashed in the middle section of the 2.1-mile Ferrin Trail, rescuers said. It connects the Hagen Trail with a saddle on Snow King Mountain.

Collins was yielding the right of way to another biker coming uphill and looked away from the trail, then crashed “quite hard,” Ciocarlan said.

He went head over heels “a few times,” bending his bike’s front wheel, Ciocarlan said.

An ambulance waiting on Upper Cache Creek Drive took Collins to St. John’s after a team of 10 rescuers and several passing cyclists carried him off the trail with a wheeled litter.

Connelly expected that Collins would remain in the hospital at least overnight.
