A couple and four children were found safe Tuesday after disappearing in the frigid Nevada mountains Sunday night, according to local officials.
James Glanton, 34, and Christina MacIntee, 25, took their two children, ages 3 and 4, and a niece, 10, and nephew, 4, to "go play in the snow" on Sunday, but they didn't return home, according to Pershing County Sheriff Richard Machado.
The region is mired in a deep freeze. Temperatures "got down to minus 21" on the mountain range Sunday night, and were well below zero again Monday night into Tuesday, officials said.
The group set out for Seven Troughs mountain range and haven't been seen since. The silver Jeep the family was riding in was last seen "doing wheelies or donuts" at a mining camp in Seven Troughs, Pershing dispatch supervisor Sheila Reitz said. The mountain range is 20 miles from their house, she added.
A Navy helicopter and a search and rescue team started looking for the couple and children immediately after being reported missing, Machado said in a statement.
Reitz said the Navy helicopter being used has night vision capabilities, and rescuers carried their search operation through the night. Additional rescuers had come from Douglas, Lander and Humboldt counties to help find those missing.
