A 73-year-old woman died this week when she fell off a cliff while on a private rafting trip on the Green River in Dinosaur National Monument in Colorado, the National Park Service reported.

The body of the woman, whose name was being withheld until family members have been notified, was recovered Tuesday.

Monument staff were notified at about 11:40 a.m. Tuesday that a member of the rafting party had fallen from a 120-foot-tall cliff sometime during the night, according to a news release.

The group had launched Monday from Gates of Lodore, then rafted 2.5 miles before setting up camp at the Wade and Curtis campsite,

Sometime during the night or early morning, the woman is believed to have climbed a slope to the west of the campsite and fallen off the cliff, according to a news release.

The victim was found Tuesday morning, and a member of the party rowed the 2.5 miles upriver to report the fatality. Cell phone reception is not available in this area and satellite phone reception may not be reliable, the park service noted.

A recovery team arrived back at the Gates of Lodore at about 7:40 p.m. with the woman's body.

Wade and Curtis is a river campsite located in the Colorado portion (Moffat County) of Dinosaur National Monument.

Dinosaur National Monument consists of over 210,000 acres in both Colorado and Utah. The monument is best known for the dinosaur quarry and the fossils preserved there, but the monument also contains spectacular canyons along the Green and Yampa rivers, the park service said.
