PINEDALE, Wyo. (AP) — The search continues for a small plane with only the pilot aboard that's been missing since Saturday in rugged terrain in western Wyoming.

The Cessna 182 left Stevensville, Mont., Saturday and had been due in Pinedale that afternoon but didn't arrive.

Sublette County Public Information Officer Steve Smith says radar lost track of the plane over upper Hoback Canyon, between Jackson and Bondurant.

Smith says two search planes were in the air Tuesday morning looking for the missing plane. He says a helicopter also is on its way from Jackson to join the search. More searchers on the ground are traveling by foot and by snow machine.

Officials haven't released the pilot's name.
