The town was physically abandoned and dismantled (and legally disincorporated) in 1950 to allow construction of a hydroelectric dam on the Dead River, which enlarged Flagstaff Lake and submerged the site of the settlement.
The song "Below" by Slaid Cleaves on his 2004 album Wishbones refers to the destruction of the town, although it is not mentioned by name. The lyrics specifically mention the Dead River, and its general location.
