Nov. 18—With more than 750 miles of trails, Yosemite National Park is a vast, unspoiled wilderness, making it a hiker’s dream. But it can quickly become a search-and-rescue nightmare when someone goes missing.
Joel Thomazin, 31, of Denair in Stanislaus County went missing on Sept. 6 on a solo hike in the park. The United States Army reservist planned to hike from Hetch Hetchy to Lake Eleanor, returning Sept. 9. A park ranger saw him on the first day of his hike near a steep section of O’Shaughnesy Dam. That’s believed to be the last known sighting of Thomazin.
After months of extensive searching, Thomazin is presumed by his family to have died on that hike. On Dec. 4, his family is planning a memorial service in Turlock, and they’re currently raising funds on GoFundMe to help his wife and 2-year-old son.
“Though it’s unlikely he is alive, without proof of his whereabouts, Joel is considered a missing person,” a post on the GoFundMe explains. “In the state of California, it can take five years to get a death certificate for a missing person which means his wife, Amanda, can’t collect on the things normally available to help bridge the gap such as Joel’s life insurance, social security, etc.”
Sadly, Thomazin is not the only person who has disappeared without a trace in the massive park. The National Park Service keeps track of cold cases on its website, where it lists a number of still-unsolved Yosemite disappearances.
Here are cases the park service is still hoping to close someday:
Richard Judd, 72, went missing on a day hike from Lower Merced Pass Lake to Red Peak Pass on July 25, 2021. He is 5-foot-11 with brown eyes and gray hair and a beard. He reportedly used white trekking poles and a navy blue daypack and was wearing a dark blue shirt and gray hiking pants when he went missing.
Sandra Johnsen Hughes, 54, has been missing since July 4, 2020. She was camping by herself in the Sierra National Forest when she was involved in a solo vehicle crash. Witnesses who saw her at the crash scene said she refused help. Since the last known sightings of Johnsen-Hughes, her sleeping bag and campsite were found abandoned. Hughes is 5-foot-3 and 150 pounds with brown hair and brown eyes.
Peter Jackson, 74, went missing after texting his son on Sept. 17, 2016, that he was hiking to Yosemite. His campsite was found undisturbed at White Wolf Campground, but no sign of Jackson was found. In 2019, his backpack was discovered between Aspen Valley and Smith Peak. He is 5-foot-10 and 155 pounds, with a gray hair and beard and blue eyes.

After arriving, Arras wanted to take a short hike to Sunrise Lakes. She departed with a 77-year-old man in their group. The man quickly wearied and took a break while Arras went onward. She was never seen again. She is 5-foot-5 and 120 pounds with blond hair. She left the camp wearing a white windbreaker, maroon-and-white striped shorts and gray hiking boots.
