Kit Carson County features a mixture of level prairie and valley lands along streams with Kansas on its eastern border. The immense Ogallala aquifer lies under several west-central states, but in Colorado's Central Plains, its presence is felt most profoundly in Kit Carson County. Here, it feeds and nourishes a flourishing irrigated agricultural economy as crops such as wheat, corn and sunflowers are watered with huge circular irrigation systems where pumps lift the life-giving water from hundreds of feet below the surface.
