A tree-covered floating landmass appears in British Columbia’s Williston Reservoir, then disappears within days, according to reports from multiple outlets. Observers describe a small, island-like patch of land that floats on the reservoir’s water before it vanishes.

The incident occurs earlier this month in the Williston Reservoir, a large man-made lake north of Mackenzie. The two accounts agree on the broad timeline and location but provide limited detail about how the landmass forms or why it disappears. Both reports characterize the event as unusual and describe the island as covered with trees.

Neither outlet offers confirmed explanations or official findings. With available information focused on sightings, the different angles largely rest on phrasing—both describe the landmass as “mysterious” and emphasize that it appears and then vanishes—rather than on new evidence. Further investigation or official statements are not reflected in these summaries.
