An Arizona grandfather is preparing for an above-the-knee amputation of his right leg after tripping and collapsing onto a blistering sidewalk in reportedly 110- to 120-degree desert heat Grant Siler, a 72-year-old Army veteran from Mohave County, was left helpless on the pavement for more than an hour before a passerby found him. What happened next shows just how dangerous extreme summer heat can become when the ground itself is dangerously hot.
On Aug. 3, Siler went for what was supposed to be an ordinary afternoon walk near his home in Bullhead City, Arizona. Before leaving, he had accidentally dropped an 80-pound cinderblock on his foot. His family describes him as a stoic man, so he brushed off the injury and went on with his walk.
Nearly a mile into his walk, Siler tripped and fell. The temperature that afternoon was reportedly between 110 and 120 degrees Fahrenheit, and he was unable to get back on his feet. He remained on the hot pavement for more than an hour.
His right leg is too damaged to ever fully heal
A passing woman eventually spotted him unconscious on the ground. She poured water on him in an attempt to revive him before calling emergency services.
According to the California Post, emergency responders found Siler in critical condition and he was airlifted to a specialized burn intensive care unit in Las Vegas. Doctors determined that his body temperature had climbed above 105 degrees Fahrenheit.
Siler had suffered severe heat stroke along with deep second- and third-degree burns across multiple parts of his body. Over the following weeks, he underwent two debridement procedures to remove damaged tissue.
Doctors later determined that the tissue in his right leg had been damaged beyond repair. The prolonged exposure to the hot surface had caused extensive damage to the muscle and blood vessels, leaving an above-the-knee amputation as the next step in his treatment. The procedure is scheduled for Aug. 31.
“He’s hurting really bad,” his daughter, Heather Crook, told reporters. Crook, who works as a nurse, said her father has never been someone who complains about pain, making it especially difficult for the family to watch him struggle.
The financial burden is now adding another layer to an already difficult situation. Beyond his ICU bills, Siler faces an extensive rehabilitation process that could include specialized medical equipment, a prosthetic and modifications to make his home wheelchair accessible. His family has turned to GoFundMe for help covering the unexpected costs. The family has so far reached 89% of their target.
The family wants to spread awareness
Siler’s experience is also a reminder that extreme desert heat can make surfaces such as asphalt and pavement dangerously hot. When temperatures climb above 110 degrees, spending extended periods on exposed ground can become a serious hazard, particularly for older people who may be more vulnerable to heat-related illness.
His family hopes that sharing what happened to Siler will encourage others to take desert heat seriously — because on days like this, the danger isn’t just in the air. It can be right beneath your feet.
