A forested island appeared out of nowhere on a Canadian lake, disappeared weeks later and returned miles away, revealing a strange natural phenomenon officials still cannot fully explain

A floating forest island appeared on Williston Lake in British Columbia this summer. Boaters discovered the unusual landmass, which was not on any maps.
