Olympic Valley, CA – Two-time X Games medalist C.R. Johnson, a halfpipe specialist, was killed Wednesday while skiing the Light Towers section of Squaw Valley’s Headwall.

Witnesses indicate that Johnson, 26, appeared to catch an edge on some rocks and tumble several hundred feet. Ski patrol attempts to revive him at the scene were unsuccessful. He was reportedly wearing a helmet.

“As a professional skier, C.R. was no stranger to the Light Towers and had skied the area throughout his inspiring skiing career,” Squaw Valley USA spokesperson Michael Gross said in a written statement. “C.R. has been part of the Squaw Valley family since birth and will be greatly missed. The loss…will deeply affect not only the local skiing community, but skiers worldwide.”

Johnson came back from a traumatic brain injury sustained when another skier landed on him at Brighton Ski Resort in Utah in 2005. He spent 10 days in a coma and had to re-learn the most basic of motor skills following his accident, but was back on skis before the end of that winter.
