Geography Monstrosity is a vanity tournament composed entirely of geography questions. It is run as a side event to one of the high school national championships. GM features 20-point superpowers, 15-point powers, and no minus-fives.
The first Geography Monstrosity was edited by George Stevens, and directed by Bryce Durgin and Katy Peters, who won praise for organizing and running the tournament on short notice. Subsequent editions have typically been edited and directed by Jeff Hoppes.
