Mount Curtiss is a fictional location featured in comic books published by DC Comics. It is associated with the Superman line of comic titles and made its first appearance by name in Superman, Volume 2 Annual #2 in 1988. Its final appearance was in Action Comics #700 in June, 1994.
Mount Curtiss is located seventy-five miles northwest of Metropolis in Kirby County. For years, the mountain housed the secret genetics research facility known as Project Cadmus. The woodlands surrounding the mountain were occupied by a bizarre motorcycle gang known as the Outsiders who maintained a haven inside the Habitat. Mount Curtiss was destroyed when a squadron of armored Team Luthor personnel overloaded Project Cadmus' power core, causing a meltdown.
