Cavanal Hill (officially Cavanal Mountain[1]), located near Poteau, Oklahoma, is billed by a local chamber of commerce as the tallest hill in the world at 1,999 feet (609 m).[2] The actual summit elevation is 2,385 feet (727 m) above sea level;[1] the difference in elevation between the summit and the Poteau River 3 miles (5 km) to the north is 1,960 feet (600 m).[3]
The billing is based on the delineation between a hill and a mountain, that being if the geographical feature were 2,000 feet or higher than its base, then it would be classified as a mountain instead of a hill.[4]
The area of Cavanal Hill was once an old mining town called Witteville. This was absorbed by Poteau since the Great Depression. Cavanal Hill has a main road that leads to the top. There, you can see a large view of Sugar Loaf Mountain, Poteau, and the Ouachita Mountains.
