Searchers were out in great numbers Tuesday morning on Owl's Head.
A Sicamous sledder believed to be between the ages of 36 and 40 has been missing since 3 p.m. Sunday in treacherous conditions, says Shuswap Search and Rescue manager John Schut.
It's a big, bad scene up here," he said at 11:30 Tuesday, March 8.
Schut says the many snow overhangs are making conditions extremely dangerous, so helicopters have been using explosives to set off avalanches.
"They need to do that so it's safe to work in that area."
RCMP are involved and 10 members of Shuswap Search and Rescue are combing the area along with "a huge number of volunteers" from Eagle Valley Snowmobile Club.
