Summary based on the NamUs case record (MP1068) and 7 other sources
In the spring of 1998, a 22-year-old man named David Barclay Miller vanished into the Arizona wilderness, leaving behind a mystery that endures to this day. On May 19, 1998, David, an experienced hiker and a seasonal employee with the U.S. Forest Service, embarked on what was planned as a two-and-a-half-day hiking trip in the scenic and rugged terrain of Sedona, Arizona. He was last seen by co-workers at the Beaver Creek ranger station, and that evening, he left a note indicating his intention to hike in the Red Rock-Secret Mountain Wilderness Area. Known for his love of the outdoors and his extensive hiking experience, which included traversing deep snows in Alaska, his disappearance under seemingly normal circumstances was both shocking and baffling to those who knew him. His vehicle was later found abandoned at the Vultee Arch Trail, a popular but challenging route, marking the last known starting point of his journey.

The initial search for David Miller was launched after he failed to return from his trip as planned. For 12 days, search and rescue teams scoured the dense and unforgiving landscape of the Coconino National Forest, an area characterized by canyons, cliffs, and thick manzanita brush. Despite the intensive efforts of official search teams, as well as the continued persistence of his family and friends, no trace of David was ever found. The challenging terrain, combined with the intense heat that eventually hampered the official search, created significant obstacles. The complete lack of evidence, including the absence of footprints, any of his gear, or any sign of a struggle, only deepened the mystery surrounding his disappearance. Authorities and his family were left perplexed as to how an experienced outdoorsman could vanish so completely in an area he was familiar with.

Over the years, the case of David Miller has grown cold, yet it has not been forgotten. Several potential leads have emerged, though none have provided definitive answers. In February 1999, the discovery of a body in Phoenix with a green backpack bearing the name 'Barclay' briefly raised hopes of a resolution, but it was ultimately determined not to be David. More recently, in 2022, an old campsite was discovered in Secret Canyon containing clothing and other items from the late 1990s, prompting a thorough investigation of the area, but no human remains were found. The prevailing belief among investigators is that David may have become lost or injured, possibly due to a fall on the slippery terrain, but without any physical evidence, this remains speculation. The disappearance of David Barclay Miller serves as a haunting reminder of the unpredictable and often perilous nature of the wilderness. An experienced ranger with a deep respect for the outdoors, his case is a somber testament to the fact that even the most skilled can fall victim to the elements, leaving behind unanswered questions and an enduring sense of loss for his loved ones.
