74-year-old doctor passes away while hiking rim-to-rim at the Grand Canyon

Hiker Dies in Grand Canyon

The National Park Service has identified a hiker who tragically passed away last week in the Grand Canyon. Dr. Dennis Smith, a 74-year-old doctor from Olympia, Washington, was well-regarded in his community.

Authorities received a call on May 15 about hikers who were unresponsive on the North Kaibab Trail. Dr. Smith was attempting to hike from the South Rim to the North Rim when he collapsed, according to friends and law enforcement.

Despite the limited cell service in the canyon, a communication was made that allowed a Park Service helicopter to respond. Medical personnel were able to revive him briefly, but he later succumbed, and was pronounced dead at the scene.

The cause of his death is currently being investigated by the Coconino County Medical Examiner’s office.

Tom Hertenstel, a doctor who had known Smith for over 30 years, expressed disbelief at the incident. “I think it was around 100 degrees out there, but he was good at staying hydrated,” Hertenstel said. “He was always careful not to push himself too hard. This just feels so unexpected.”

After a brief service in the Navy, Dr. Smith transitioned from family practice to becoming an orthopedic surgeon. He started his own practice, Olympia Orthopedics, and met Hertenstel in 1994. “We supported each other in surgeries every Tuesday for three decades,” Hertenstel reminisced. He mentioned Smith had participated in various athletic challenges, including ultra-trail runs through the canyon, but had shifted focus to hiking in recent years.

Before stepping back from running, the duo had completed an Ironman competition and summited Mount Rainier together. “He was very fit and active. This wasn’t just a casual outing; it was a significant hike, but still,” Hertenstel continued, “it doesn’t sit right with me that this could happen to him.”

Smith was known for his dedication to his patients, specializing in trauma, hip, and knee procedures. Hertenstel praised him, saying, “He was always eager to help others, even after he retired in 2021.” Colleagues viewed him almost like a craftsman in his field.

In addition to his professional legacy, Smith leaves behind his wife Evelyn and their four children, celebrating their 50th anniversary together. He also had several grandchildren who shared his love for hiking and running.

The National Park Service has urged visitors to adequately prepare before heading into Grand Canyon National Park, especially considering the intense heat. Rangers recommend avoiding hiking in the inner canyon during peak hours of heat, between 10 AM and 4 PM, advocating for caution.
