Coffeyville is a city in eastern Kansas, some its border defined by the Verdigris River, which, at 679 feet, is the lowest point in the state. Its almost as if this sloping state is anchored at Coffeyville and the surrounding area in the east, and rises gradually as you go west, eventually crossing the state border and soaring up dramatically when you get about two-fifths of the way through Colorado. Along the way west on this upward slope, before you cross the state line, is Mount Sunflower at 4039 feet. The state is flat, but it is not level. It gradually rises, like a table with two short legs in the east and two long legs in the west.
