Authorities say they've found two adults and four children who've been missing in the frigid mountains of northern Nevada since Sunday.

Pershing County sheriff's officials say the adults and children were being taken to Pershing General Hospital after they were found Tuesday. All were in good condition.

Temperatures in the nearby town of Lovelock dipped to 16 degrees below during the search.

Crews launched a search Sunday night for 34-year-old James Glanton, his 25-year-old girlfriend, Christina McIntee, and the four children: a 10-year-old, two 4-year-olds and a 3-year-old.

Officials say the group went to the Seven Troughs area Sunday to play in the snow, but never returned home.

Authorities say about 200 people have joined the search for a couple and four young members of their families missing in the bitter cold in a Nevada mountain area since Sunday.

Pershing County sheriff's dispatcher Sheila Reitz said the volunteers turned out Tuesday to assist authorities from five counties, game wardens and state emergency workers searching the area about 100 miles northeast of Reno.

Reitz says a signal from the missing woman's phone showed they were in the Seven Troughs area 25 miles northwest of Lovelock on Sunday.

Since then, the search has been expanded to a much wider area with two airplanes and two helicopters assisting ground crews.

The low hit minus-10 degrees early Tuesday after dropping to 16-below the previous night.
