It’s been a busy weekend for North Shore Rescue crews, who were called to Crown Mountain this morning for the third time since Saturday.

Crews rescued a pair of hikers at the bottom of a 250-foot cliff on the mountain Monday morning.

The two men were supposed to return from their hike by 8 p.m. Sunday, but never did. They spent the night outside in sub-zero temperatures.

North Shore Rescue team leader Mike Danks told reporters the men appeared to be moving around and uninjured, but could be suffering from the cold weather.

“They were basically stuck,” Danks said. “Last night was probably minus-4 to minus-6. The wind’s gusting 40- to 50-k up there, so these guys are going to be very hypothermic.”

On Sunday, North Shore Rescue air-lifted a 67-year-old man off of the same mountain after he had suffered a leg injury.

That rescue came roughly 24 hours after another airlift on Saturday. Crews rescued a man who fell close to 30 feet and was lucky enough to catch a tree to prevent him from falling farther. He suffered an arm injury and was pulled out by a helicopter and a long line.

After three helicopter rescues in two days, North Shore Rescue is warning hikers that pockets of snow on popular trails can be treacherous.

Despite unseasonably warm weather in Metro Vancouver, it’s still winter in the mountains.
