James Glanton and his two children, along with Christina MacIntee and her niece and nephew, went missing on Sunday.
The group had gone to the Seven Trough mountain range to play in the snow.
A massive search party, involving more than 200 people using cars, planes and helicopters, scoured the 6,000 square mile area after authorities were unable to recover the group's jeep.
The group was found in good condition, spotted by ground-search crews, in the Trinity Canyon area.
Authorities were concerned about the children, who ranged from 3-10, being able to last in the sub-zero temperatures the area experienced over the past two nights.
Many have been celebrating the family's safe return, including Nevada Governor Brian Sandoval.
Very glad to hear the missing family in Lovelock has been found and they are safe! Thank you to all who worked so tirelessly to find them!
