Mysterious floating island found in Canadian lake

Neutral summary

BC Hydro says a floating island covered with trees, spotted earlier in the Williston Reservoir in British Columbia, has drifted ashore about 30 kilometres northwest of where it was last seen. The island, roughly the size of two football fields, appeared on satellite images and then vanished, prompting speculation that the footage was an AI-generated fake. A BC Hydro spokesperson said the island may sit on an unstable mass of logs and decaying debris, so boaters are advised to stay away. Officials believe record-high water levels may have caused the island to break off from the shoreline.
