Cement Worms
Cement Worms are creatures from Lumberjack Folklore similar to Ice Worms. They have the scientific name “Vermes Shatteratus.” They can be found in aging concrete sidewalks and building foundations and are thought to be the reason that cement crumbles. They can be found throughout the US, and according to mythologist Ralph Walker, rockslides in the Rocky Mountain area could indicate Cement Worms have moved to canyon walls.
