Copied from the Denver post:
A woman was killed Saturday and her companion severely injured when their Jeep tumbled from the top of a steep off-road trail in Summit County.
The fatal accident happened at the top of Radical Hill, a 12,500-foot summit that can be reached along a narrow road used by hikers and four-wheel-drive vehicles.
At the summit, "the vehicle came off and went approximately a half mile down the side of a mountain before coming to a rest," said Joe Ben Slivka, a spokesman for the Summit County Rescue Group.
He described the Radical Hill trail, at the southern edge of Summit County, as very popular with Jeep drivers. "It's a difficult four-wheel-drive trail, but not impossible," he said. "We do have a fair number of accidents that occur there annually."
