Officials said 10-year-old Malachi Bradley went missing in the high Uintas in the vicinity of the Paradise Park Campground and was gone for more than 24 hours.
Crews said Bradley got lost and tried to find his way back but couldn't so he toughed out the night in his jacket.
K9 crews sniffed out the boy Monday afternoon just before 3 p.m.
He has been flown off the mountain and is back with family.
The Facebook page “Malachi Bradley Rescue Effort” posted a photo of the child and updates on efforts to coordinate volunteers for a search.
A post on the Facebook page states that volunteers are no longer being allowed to go out in search teams as of Sunday night, but that there could be more search teams allowed out in the future.
