The body of the man missing since Thursday was found on a property adjacent to his Rimrock Road home, the Tuolumne County Sheriff's Office reported Sunday afternoon.
The press release said foul play is not suspected.
"Our most sincere condolences to the Clark family," the news release said.
The 66-year-old Sonora man was last seen at his home around 9:15 a.m. Thursday. His vehicle, wallet, and cell phone were all found at his home.
In announcing her father's death on Facebook, Angelic Hardie said, "Thank you to all that have helped. The family appreciates privacy at this time."
The family searched for days and questioned whether Clark could have gone far. Hardie said Friday on Facebook that Clark had two artificial knees.
"We have been searching since 7 a.m. entire six-acre property and neighborhood. He usually takes his quad when he goes around the neighborhood and the quad is in his garage," she said.
She said they had contacted all the places he normally visited.
