William Ott, 65 at the time of his disappearance, embarked on an ambitious three-week hiking expedition in a secluded part of the Hualapai Indian Reservation on 5 April 2012. He was scheduled to conclude his journey on 28 April but failed to return, prompting friends and family to report him missing shortly after his overdue arrival was noted.
The initial search for Ott involved the National Park Service and the Arizona Department of Public Safety, who conducted extensive searches of the area but were unable to locate him. The search efforts spanned several days and included hundreds of volunteers, yet Ott’s whereabouts remained a mystery.

The recent breakthrough in the case occurred when members of the Hualapai Tribe discovered human remains near the area where the search for Ott originally began. Subsequently, the remains were entrusted to the Coconino County Sheriff’s Office and examined by the Coconino County Medical Examiner. Through DNA analysis, the authorities confirmed that the remains belonged to Ott, a finding that was officially announced on 21 July 2023.
Scott Thybony, a close friend and fellow hiker who participated in the search for Ott, shared his memories of the missing hiker. Thybony stressed that Ott was an experienced outdoorsman, having previously walked the length of the Grand Canyon in 1981—a feat that made him the first person to traverse its north side. Thybony described Ott’s fascination with ancient rock art, stating, “He was searching for thousand-year-old rock art panels in a remote area of the Grand Canyon when he disappeared.”
In an interview, Thybony recalled Ott’s passion for ancient pictographs painted thousands of years ago. He noted, “Several times Ott had stopped by my office to talk about his passion. The multi-coloured pictographs fascinated him, and being hard to find and even harder to reach added to the attraction.” Ott’s enthusiasm for these hidden treasures drew him back to Arizona annually to search for them.
Prior to his disappearance, Ott had embraced a self-sufficient lifestyle in Cave Junction, Oregon, where he built a cabin and lived off the grid. He had sold most of his possessions to pursue his passion for hiking and exploring remote areas. However, the circumstances surrounding his disappearance have raised questions, particularly regarding the conditions in which his remains were found.
Thybony mentioned that Ott’s body was discovered at the base of a 15-foot cliff with his main backpack missing, though the cause of death has not yet been disclosed by the authorities. This detail has led to further speculation about the events leading up to his tragic end.
The confirmation of Ott’s identity provides a sense of closure for his family and friends who have long awaited news of his fate. However, it also highlights the potential dangers faced by hikers in remote areas like the Grand Canyon, where unpredictable terrain and challenging conditions can lead to dire outcomes.
As the investigation continues, the case serves as a reminder of both the beauty and peril of wilderness exploration. The Coconino County Sheriff’s Office has not provided further updates as they continue to piece together the circumstances surrounding this heartbreaking incident. The community, along with Ott’s friends and family, mourn the loss of a passionate explorer who dedicated his life to uncovering the hidden wonders of the natural world.
