A Grand Canyon missing hiker reported lost near the North Rim has been found alive. Gerald Guinn, 83, of Kanab, Utah, was located at 6:30 p.m. on 22 July during a helicopter reconnaissance flight, 2.5 miles from the point where he was last seen, according to FOX 10 Phoenix. The recovery brings to a close a search operation that had mobilised ground teams, helicopters and drones across one of the most challenging search environments in the American south-west.
Search Operation Involving Multiple Agencies
Guinn was reported missing on the evening of 21 July after his hiking partner alerted the Grand Canyon Regional Communications Center at approximately 5 p.m. The partner stated he had become separated from Guinn during the day. National Park Service (NPS) personnel mobilised alongside Coconino County Search and Rescue and Kane County Search and Rescue, conducting both ground and aerial operations across the North Rim area.
Guinn is five-foot-ten and weighs 140 lbs. He had last been seen walking along Forest Service Road 610 (Dog Saddle), near the north-east boundary of the park, wearing jeans, a long-sleeved tan shirt and a baseball cap. He was carrying no technical gear or camping equipment, a detail that heightened concern given the conditions in the park this summer.
The NPS had asked members of the public to contact the NPS ISB Tip Line at 888-653-0009 with any information about Guinn’s whereabouts while the search was under way.
Grand Canyon Missing Hiker Search Set Against a Summer of Extreme Heat
The Guinn case unfolded during a summer in which Grand Canyon rangers have been under sustained pressure to manage heat-related emergencies. Temperatures in the inner canyons have reached as high as 130°F, a product of the park’s geology amplifying ambient heat. The NPS has been advising visitors to avoid strenuous hiking between 10 a.m. and 4 p.m., when Inner Canyon temperatures can reach 109°F (43°C) in the shade.
Four people died of heat-related illnesses at the Grand Canyon in June alone. An 18-year-old died on the Bright Angel Trail on 3 June. A 72-year-old man died on the South Kaibab Trail on 12 June. An elderly couple died on the North Kaibab Trail on 16 June. Heat-related ailments, alongside pre-existing medical conditions, represent the most prevalent cause of death in the park, and this year’s toll has already climbed above the yearly average with two months of summer still remaining.
The NPS extreme heat warning states that ‘summer hiking below the rim should be limited to the early morning and evening hours’ and that visitors are ‘strongly advised to avoid strenuous hiking between 10 a.m. and 4 p.m.’
The Park’s Scale Creates Lasting Search Challenges
Grand Canyon National Park covers nearly 2,000 square miles, making it the fourth largest national park in the contiguous United States. That scale presents an enduring operational challenge for search and rescue teams, particularly during periods of extreme heat that constrain the hours in which ground crews can safely operate.
The difficulty of recovering missing persons in the park was underscored earlier this month when DNA tests confirmed, on 1 July, that human remains discovered by members of the Hualapai Tribe on their reservation were those of Bill Ott, a hiker who had gone missing in April 2012. Coconino County Medical Examiner’s Office had received the remains from the tribe last December.
Ott had been the first person to complete a thru-hike of the full length of the Grand Canyon from the north side, in 1981, a journey that took 78 days. He also spent years documenting ancient Hualapai rock art. Anthropologist Scott Thybony described Ott’s painstaking approach to that work: ‘There’s a series of archaic rock panels that dates back between 3,000 and 4,000 years ago, possibly older. He would go pixel by pixel, hours after hours, trying to match the colors with broken-off pigment, removing smoke stains. It was a painstaking effort, and it went on for years.’
With Guinn now located, search and rescue teams will turn their attention back to a summer season that, by any measure, has already tested the park’s emergency capacity to an unusual degree.
