Banff staff explore unknown underground structure found at Lake Minnewanka

Parks Canada is investigating a mysterious underground structure discovered near Lake Minnewanka in Banff National Park. The discovery was made after a section of ground collapsed in early May, revealing the subterranean feature.

Officials report that the structure is made of untreated wood, featuring log walls and rough-cut planks. An initial assessment suggests it dates back to before the 1950s or 1960s. While there is no historical or photographic record of such a structure, authorities speculate it might be connected to the former Lake Minnewanka campground, which operated from around 1944 until its closure in 1952.

Heritage specialists are currently on-site, working to determine the structure's origin and its potential historical or archaeological significance. The area surrounding the discovery has been cordoned off with fencing to ensure public safety due to the site's instability and ongoing investigation.

The Lake Minnewanka Campground was eventually converted into a day-use area after the Two Jack Lake Campground opened. The current investigation aims to shed light on this unexpected subterranean find, adding a layer of historical intrigue to the popular tourist destination.
