Colorado is a state of wild contrasts. From the flat plains of the eastern portion of the state to some of the Rocky Mountains' highest peaks to the high desert and red rock country of the western reaches of the state, the landscape is incredibly varied, home to many diverse ecosystems and natural marvels, and supports a thriving hunting and outdoors culture that draws people from around the world.
