The search continued Thursday for two Colorado men missing since last weekend in the Nine Mile Canyon area of east-central Utah's Carbon County.
Carbon County Sheriff James Cordova said that the natural gas pipeline construction workers had not been seen since late Saturday.
"We haven't had any luck so far in finding them," the sheriff said Thursday. "On Monday while looking for a couple elk hunters from Nevada who we found alive and well we asked around. Then on Wednesday I had a deputy up there all day looking in gullies and along the road. Now we're doing a more organized, extensive search using our deputies, and we have search-and-rescue on standby, too."
