Nine days into the search for missing hiker Tyler Wright, new clues that he could still be alive continue to turn up.
The latest signs -- a campfire, ski pole tracks and distinctively large footprints -- have turned up just west of Bull Creek, near Squamish, B.C.
Thursday, specialized trackers were flown in to figure out if the footprints match up with Wright's whopping size-16 feet, as well as the tread on his shoes.
On Tuesday, searchers found signs of someone trying to climb up a small cliff.
"It appears that somebody this season has passed through there, they've tried to climb some of that steeper area, and it's given way, and they've slid a short distance," John Willcox of Squamish Search and Rescue told CTV News.
A large wilted leaf, with dimples that seem to match Wright's shoe tread, is also being considered evidence of the path taken by the hiker.
Willcox said that searchers have been watching for marks left by Wright's ski poles, too.
"What we've found is when he's had to get up over rocks and logs, that they've left scrapes on the rock," Willcox said.
The 35-year-old was last seen on Aug. 10, when he headed out onto the trail alone. Squamish RCMP say Wright is not an experienced mountain hiker and did not take a sleeping bag, tent or compass with him into the woods.
Wright had planned on hiking overland to the Coquitlam area in four or five days. He was reported missing on Aug. 18, and search crews have been looking for him ever since.
Spotting someone from the air is difficult, so Wright's friends and family are paying for a helicopter with two high-definition cameras strapped to its belly.
They've been posting the footage online in the hope that people at home might notice signs that searchers have missed.
