Palo Duro Canyon State Park
Palo Duro Canyon is located on the southern high plains, an area called El Llano Estacado or staked plains. The rim of the canyon is considered part of the short grass prairie while the elevated moisture of the canyon floor supports a greater diversity of plants including some medium and tall grass species along with shrubs and trees. Common plant species include sideoats grama, big bluestem, Indian blanket, star thistle, fragrant sumac, mesquite, and cottonwood trees. Several juniper species are also common.
