ELDORADO SPRINGS, Colo. (CBS4) – The body of a missing hiker was found so far off the trail that helicopters struggled to locate the area.

The body of David Robles, 53, was found down a 600 foot ravine, more than a half mile from a scenic overlook on the Rattlesnake Gulch Loop Trail in Eldorado Canyon Wednesday afternoon.

Robles, of Westminster, had been hiking the popular trail alone on Saturday.

“It’s a very technical area,” said Boulder County Sgt. Dave Booton. “He either fell or slipped. We don’t know yet. That’s the other part of the investigation.”

Dozens of search and rescue personnel combed the area for three days. A woman who was hiking with her kids told crews Wednesday morning that she recognized Robles from Saturday, which helped narrow down the search.
