Two snowmobilers are in good condition after being stranded overnight east of Enderby.
Vernon Search and Rescue was called out at 8 p.m. Monday after two snowmobilers didn't return from Hunter's Range.
"They got themselves down into a drainage area," said Pete Wise, search manager.
"Once you get into a drainage, it's almost impossible to get out."
SAR members scoured the Cooke Creek area until 3 a.m. Tuesday.
"There's lots of snow in the backcountry and several spots where there's a risk of avalanche, We wanted to make sure they weren't in an avalanche," said Wise.
Helicopters began flying over the area at about 7 a.m. and the snowmobilers walked up a ridge where they were picked up before 9:30 a.m.
"They appear to be fine," said Wise of their condition.
This is the 19th case of Vernon SAR assisting snowmobilers since Jan. 1.
"It puts significant pressure on our volunteers," said Wise.
"We've been very busy. It works out to one to two call-outs a week."
Wise is urging snowmobilers to be prepared when they go into the backcountry, particularly with equipment and the ability to survive if stranded.
"It may be spring in the valley bottom, but it's still winter in the mountains," he said.
On Saturday, Vernon Search and Rescue assisted Shuswap Search and Rescue in assisting a snowmobiler in the Owls Head area of Hunter’s Range.
The individual had an injured hand and once SAR crews were on scene, he was assessed and transported to Kelowna General Hospital.
