NABSQNO 16S-539740-4242725. Ravine Arch is a cave natural arch that has eroded through layers of Tar Springs Formation. It is located in the Yellow Birch Ravine Nature Preserve, about a mile east of Taswell, in Crawford County, Indiana. The Preserve is managed by the Indiana Department of Natural Resources. Access is via a public hiking trail that passes several natural features before leading to the drainage the arch is in. Ravine Arch has a span of about 25 feet. Two excellent photos of the arch that show interesting perspectives are found here and here.
