21-year-old climber dies after sustaining 'major injuries' in fall off Devil's Tower

A 21-year-old rock climber died after "sustaining major injuries" while climbing Devil's Tower National Monument, authorities said.

The fall occurred on Sunday shortly before 8 p.m. when Devils Tower Law Enforcement was informed that a rock climber, Stewart Phillip Porter, a 21-year-old from Eau Claire, Wisconsin, was rappelling down the second pitch of El Cracko when he fell and sustained "major injuries" in a fall, according to a statement from the National Park Service released on Monday.

"Porter's partner was stranded and later rescued from the wall of the Tower, with help from Devils Tower Lodge Climbing Guides and Buck Wild Climbing Guides," officials said.

Over the 100 plus year climbing history at the Tower, there have only been seven climbing deaths, according to the National Park Service.

"While climbing fatalities at Devils Tower are infrequent, it is still inherently dangerous," park officials said.

The National Park Service took the opportunity to remind the public of proper safety measures to take while climbing.

"Check the local weather forecast before climbing and observe changing weather conditions," officials said. "Watch for animals (stinging insects, birds, rodents and reptiles all live on the Tower) ... [and] Consult multiple sources for information on a route, as suggested gear varies between guidebooks."

"The majority of climbing accidents and deaths on the Tower occur during the rappel. The National Park Service does not maintain anchors - inspect all anchors and back them up if necessary. Ensure you know the location of your rappel route before you begin," officials said. "Start rappels over the nose of columns to prevent ropes from jamming in cracks. Avoid knocking loose rock onto climbers below. Many rappels require two ropes; know the distance of your planned rappel before beginning."

Devils Tower expressed appreciation for Devils Tower Lodge, Buck Wild Climbing Guides, Hulett EMS and the Crook County Sheriff's Office and monument staff who assisted in search and recovery efforts, and offer condolences to the family, park officials said.
