The Pomona Natural Bridge is located in the Shawnee National Forest in Southern Illinois. It is a short downhill hike through a mature forest to the natural bridge. Made of sandstone the bridge is 90 feet long, 6 to 9 feet wide and 25 feet above a small stream. It is one of those unique sketching location I have found in Southern Illinois, interestingly this site was a popular tourist spot even in 1877 when the unknown artist's sketch below was drawn.
