NABSQNO 14S-575960-4301160. This unnamed arch is a caprock natural arch eroded through a remnant outcrop of Dakota sandstone. It is located at a state-maintained rest area along east-bound I70 (mile 224) in Ellsworth County, Kansas. Because of its fragile nature, the state has placed a fence around it to prevent children from climbing on it. It has a span of about 7 feet.
