The long shadows of trees point you toward the arch. Reflective light intensifies the dramatic layers of the overhanging sandstone rock. The direct light on the lower section of rock reflects well in the pool of water. Finally, the hillside on the backside of the arch is illuminated just enough to provide visual depth to the scene.
A small tributary of Bear Creek in rural Fountain County slowly carved into the Mansfield Sandstone laid down 230 million years ago. The layers and textures of the sandstone walls provide a geologic marvel as you walk around the short .8-mile trail that leads through the Arch.
Portland Arch was owned by Boy Scouts of America from 1938 till 1966. At that point, the land was purchased by The Nature Conservancy and later transferred to the Indiana DNR. In 2002, an additional 142 acres was added by the Indiana Heritage Trust, bringing the total acreage to 435. It’s a great place to explore.
