A British Columbia man was snowmobiling in the Kootenay Pass area of the province when his sled rolled over an unmarked opening to a mine shaft that was concealed by snow.

According to CBC.ca, fifty-eight year old Ken Gadicke fell back into the mineshaft and his sled fell in after him. Gadicke fell more than 80n feet, but was fortunately wearing a helmet and other protective gear. He suffered a broken arm and an injured ankle.

Gadicke’s son and another riding companion were able to get to the injured rider and bring him back up within about 30 feet of the surface and rescuers were able to retrieve him from there.
