Utah County authorities responded to the scene of a fatal single-vehicle rollover just north of Lehi on Friday morning.

The vehicle was found near the southbound lane of E. Frontage Road at Point of the Mountain in Utah County, according to a statement released by Utah County Sheriff’s Office Sgt. Spencer Cannon, the department public information officer.

There was a single occupant in the vehicle at the time of the rollover.

When officials arrived on scene, an 81-year-old Utah County man was declared dead. The man was identified Saturday as Darrel George Field of Pleasant Grove. 

Field's granddaughter remembers her grandfather as a "brilliant" man. 

"He was a gem of a human," she wrote in a message posted to Instagram. 

His granddaughter reminisced about Field's ability to fix anything, his knowledge of computers, his love for his country and his ability to do perfect impressions of Donald Duck. 

Additionally, she remembered seeing his patents hung on his wall for his help in creating the carbon monoxide detector and part for modern elevators. 

"I will miss him so much," she continued. "There is comfort in knowing he is no longer restricted by the physical limitations he was facing and his spirit no longer constrained to the pain and difficulties of this life."

The Lehi Fire Department also was called to the scene.
