CODY, Wyo. (AP) — Rescuers are continuing a difficult search for a Montana day hiker who's been missing in the Clarks Fork Canyon area since Oct. 2.

About 10 people are reportedly helping in the search for 32-year-old Jason Shefelbine of Billings.

Shefelbine was last seen near the Clark's Fork River and Antelope Butte. His vehicle was found on Oct. 4 off Chief Joseph Highway.

Park County search and rescue members, aided by aircraft, have had to rappel down cliffs to the river in their efforts to find Shefelbine.
