16. A Firetower's Secret (William A. Switzer Provincial Park, Alberta, Canada)

When a seasoned wildfire spotter fails to check in for her scheduled radio call, her supervisor ventures out to make sure she is okay. When he arrives, she was gone and has never been seen since. How did she disappear from her remote post at Athabasca lookout? It's been 16 years and her case remains unsolved.

If you have any information on this case, call Hinton RCMP at 780–865–2455 or Crime Stoppers at 1–800–222–8477.
