Scott Prevost, 26, of Anchor Point, was reported missing Sunday afternoon after his snowmachining partner returned without him.

Prevost and Dan Giorgi, also of Anchor Point, left from North Fork Road in Anchor Point and traveled to Caribou Lake Lodge. On the return trip, the two got separated, troopers said. Giorgi returned safely but reported Prevost missing when he didn't come home.

Snomad club searchers looked for Prevost Sunday night. Troopers and the U.S. Fish and Wildlife Service joined in Monday morning. Troopers were using one helicopter to look for Prevost, and two other helicopters were en route when Prevost arrived at a residence off Deep Creek Farm Road in Ninilchik.

Meanwhile, Duane Christensen and his friend James Pastro decided to join the search, but Pastro rolled his snowmachine Monday afternoon and injured his upper leg. The pair called for help using a cell phone. A Maritime Helicopter, with a Homer Volunteer Fire Department medic, responded and brought Pastro to South Peninsula Hospital.

According to Trooper Sgt. Jim Hibpshman, Prevost's snowmachine had become stuck in deep snow. When Prevost was unable to free it and couldn't find his companion, he began walking.

Hibpshman said Prevost must have walked at least 10 miles Sunday night and Monday morning.

"He had a long walk last night," Hibpshman said. "He's tired and hungry, but he's in good shape."
