Tragic Loss in the Grand Canyon: A Community Remembers Dr. Dennis Smith
Recently, tragedy struck the Grand Canyon when beloved Olympia, Washington, doctor, Dr. Dennis Smith, passed away while hiking. At 74 years old, Smith was a well-respected figure, known for his dedication to his practice and community.
On May 15, the National Park Service received a report about an unresponsive hiker near the North Kaibab Trail. Dr. Smith, who was attempting a rim-to-rim hike from the South Rim to the North Rim, collapsed during his trek. Thanks to the proximity of the trail to the trailhead, park staff were able to send a helicopter for assistance.
Emergency medical responders attempted to revive Smith but, sadly, he was pronounced dead at the scene. The cause of death is currently under investigation by the Coconino County Medical Examiner’s Office.
Dr. Tom Helpenstell, a close colleague of Smith for over three decades, expressed shock at the news. Having hiked the canyon together in hotter conditions, he described Smith as someone who was always cautious and mindful of his health. Helpenstell said, “He always stayed hydrated and knew his limits. This seems like a freak occurrence.”
A former family practice doctor turned orthopedic surgeon, Smith founded Olympia Orthopaedic Associates, where he began his fruitful career in medicine. He and Helpenstell worked side by side, performing surgeries and consulting for years. They even ran across the Grand Canyon three times and tackled other significant physical challenges together, including climbing Mount Rainier and competing in Iron Man events.
After years of intense activity, Smith transitioned from running to hiking, particularly enjoying his winter months in Tucson, Arizona. Helpenstell emphasized Smith’s fitness and activity level, remarking that the Grand Canyon hike was a planned, though challenging, endeavor.
Smith’s medical contributions extended beyond the operating room, as he was known for his willingness to help anyone in need. Even after retirement in 2021, he continued to support his practice by being available for emergencies. Helpenstell described him as “an amazing man” who contributed significantly to the orthopedic community.
Beyond his professional life, Smith was passionate about health and nutrition. He was a constant learner, often jokingly called an encyclopedia of knowledge by his friends. He aimed to maintain his health through various activities, like playing pickleball, believing it would keep his mind sharp. His dedication to fitness made his untimely passing all the more shocking to those who knew him.
Dr. Dennis Smith leaves behind his wife, Evelyn, with whom he was set to celebrate their 50th anniversary, along with four children and grandchildren who shared his love for hiking and outdoor activities. His family and friends are mourning the loss of a man who not only devoted his life to healing but also embodied the spirit of adventure and zest for life.
In light of this tragedy, the National Park Service urges visitors to the Grand Canyon to be mindful of the harsh conditions, especially during the peak heat hours between 10 a.m. and 4 p.m. They recommend that hikers be adequately prepared and self-reliant, emphasizing that assistance may be delayed in case of an emergency due to safety measures.
The story of Dr. Dennis Smith serves as a poignant reminder of the unpredictability of life and the importance of outdoor safety. His legacy as a caring physician and an active community member will not be forgotten. All who knew him are left to cherish his memory and the impact he had on their lives.
