BC's floating forest island appears, vanishes, and reappears miles away on Williston Lake

A forested island appeared on Williston Lake in British Columbia, measuring roughly 150 by 75 meters and not found on maps. Within a day it disappeared, then a second appearance occurred about 20 miles away. BC Hydro says the mass is a naturally formed floating island of trees and vegetation growing on woody debris, likely aided by higher water levels that buoy the island; satellite imagery confirmed its existence, and experts note similar floating islands can form in other places. While it could persist for years if conditions stay favorable, authorities warn it is unstable and unsafe to approach.
