Mysterious island emerges in Canadian lake then disappears in a matter of days

The bizarre floating landmass was spotted in British Columbia’s Williston Reservoir — a sprawling man-made lake north of Mackenzie — earlier this month, according to CBC. Local Rocky Avery said photos and video of the island were taken by a boater and later shared with him before he posted them on social media, where they quickly went viral. “It was a pretty amazing sight to see, never seen anything like that in my 40 years in this country,” Avery told the outlet. “There was a big fishing derby coming up, so I wanted to make sure everybody was aware of what was going on. And I wanted BC Hydro to know too that it was out there, just in case it was floating down their way.” BC Hydro — a government-owned utility company that generates and delivers clean hydro-electric power to most of British Columbia — initially questioned whether the mysterious island was real.
