The search for Tyler Wright entered its eighth day on Wednesday, after crews discovered more evidence the missing hiker could still be alive.

Searchers are now concentrating on an area called Bull Creek near Squamish, B.C., a day after crews located a 15-metre-long slide path down a rock face. They think Tyler tried to climb up out of the creek bed but slid back down instead.

Size-16 footprints believed to be Tyler's were found in the creek bed near the slide area, confirming for rescuers that he continued on from there.

The distinctively large shoe impressions were first found along the Boise Creek trail near the Bull Bowl last week, and more prints were found Monday afternoon.

Searchers are now working the valley creek bed where they found the impressions, but have described the terrain as "heinous" and difficult to traverse.

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.
