How much might a smart dog like Toto know of Kansas topography? With a good push and a few pulls along the way one could coast from Mt. Sunflower, near the Colorado border, to the Verdigris River at the Oklahoma border, and drop 3,360 feet by doing it. By no description is Mt. Sunflower a mountain, but it is the highest point in Kansa, and the Verigris point the lowest.
