RIVERTON, Wyo. (AP) — Fremont County authorities say two men are unhurt after their truck got stuck in a snowdrift and they were missing in a remote area for two days.

Relatives called the Sheriff's Office around 10:30 p.m. Friday to report missing 57-year-old Dale Smith and 58-year-old David Smith. The Associated Press reports the men had been due back from a day trip in the South Pass area a few hours earlier.

Search teams looked for the men Friday night, Saturday and Sunday morning. Four planes and a helicopter took part in the search Sunday.

The men called from a rest area between Lander and Jeffrey City half an hour after searchers found their pickup.

They said they walked five miles before catching a ride with an oilfield truck driver.
