LOVELOCK, Nev. — A search continued Monday in the remote mountains of northwest Nevada for a couple and four children who went to play in the snow and haven’t returned after a night of subzero temperatures.
Pershing County deputies said aircraft and crews on the ground were searching for James Glanton, 34; his girlfriend, Christina McIntee, 25; and the four children: a 10-year-old, two 4-year-olds, and a 3-year-old. The relationships between the couple and children were unclear.
Officials said the group went to the Seven Troughs area Sunday in a silver Jeep with a black top but hadn’t returned home. It was unclear what supplies they might have been carrying or whether they were able to communicate with rescuers.
‘‘I’m hoping they all huddled together and stayed in the Jeep,’’ Nevada Highway Patrol Trooper Chuck Allen said Monday. ‘‘That would be a best-case scenario.’’
The situation was considered especially urgent because of unseasonably cold temperatures. In the nearby small town of Lovelock, temperatures dipped to 16 below zero early Monday, National Weather Service meteorologist Mark Deutschendorf said.
Dispatcher Jerry Reid said the search began Sunday evening and continued through most of the night. A Navy search and rescue team was assisting Pershing County authorities, and the Civil Air Patrol was expected to join the effort, Reid said.
The Seven Troughs is about 20 miles northwest of Lovelock and about 80 miles northeast of Reno.
‘‘It’s remote, and it’s rocky,’’ Nevada Department of Wildlife spokesman Chris Healy said. ‘‘There are good dirt roads into the place, but they are dirt roads, and it is cold and snow, so it’s not ideal.’’
