Drove to Kansas today - my goal was to visit Mt. Sunflower which is the highest point in Kansas. It is just across the border with Colorado and stands at 4029 ft ASL.
Then just for information sake I wanted to find out where the lowest point in Colorado is. Turns out not very far from Mt. Sunflower, on the Arikaree River just before the border with Kansas at 3317 ft. ASL
