NABSQNO 16S-342545-4152320. Cedar Wonders Arch is an abandoned natural arch eroded through Drury Member sandstone, part of the Caseyville Formation. It is located above a short tributary of Cedar Creek, within the Shawnee National Forest, about a mile south of the small town of Reyoldsburg, in Johnson County, Illinois. Access requires a short, but complex hike through the woods. There is no established trail to the arch.
Cedar Wonders Arch has a span of about 9 feet and a height of about 5 feet. Thanks to Robert Tyson for the location of this arch.
