Mount Sunflower is what U.S. state's highest point?

Mount Sunflower is the highest natural point in the state of Kansas. At 4,039 feet (1,231 m), it is 3,300 feet (1,010 m) above the state's topographic low point in southeastern Kansas. It is less than half a mile (0.8 km) from the Colorado state border and close to the lowest point in Colorado.

Mount Sunflower is located on private land owned by Ed and Cindy Harold, who encourage visitors to the site. Amenities include a picnic table, a little free library, a sunflower sculpture made from railroad spikes, and a plaque on the site stating, "On this site in 1897, nothing happened." As of 2015, however, that sign is missing, evidently stolen. Additionally, there is a mailbox on site with a registration book inside where you can write your name, where you are from, and how many in your party.

Mount Sunflower blends into the surrounding terrain and doesn't appear as much of a mountain because Kansas increases in elevation from the east side of the state to the west.
