Range: In New Mexico, the known range includes the San Juan River in San Juan County, to approximately five miles east of the Arizona state line, but the snake may occur along tributaries in the immediate vicinity. California Kingsnake morphs may also be found in part of the Gila River drainage in the southwestern portion of the state, although this likely an integrade zone with the Desert Kingsnake (L. g. splendida) and individuals resembling each subspecies have been found close to the border in Arizona. Because the snake is found in the drainage of the Little Colorado at St. Johns, Arizona there is also a possibility that it follows the Zuni River from Arizona into Cibola and McKinley counties in western New Mexico.
