Thanks to a generous donation by Louis and Sandra Decker, the 33-acre Hall's Creek Canyon has been added to the System of Natural Areas. It provides direct protection of a portion of Hall Creek, a spring-fed tributary of Janes Creek. It also includes a narrow and deeply-incised, bluff-walled canyon with approximately 260 feet of local relief and a variety of geologic features in the creek-bed and canyon walls. Canyons of this sort are especially uncommon in this part of the Ozarks, which is generally less rugged and more gently rolling than other ecoregions to the west and south. The natural area is the only known site in Arkansas for the wall-rue spleenwort (Asplenium ruta-muraria), a rare fern of vertical cliff faces.

From Ravenden (Junction of US Highway 412 and State Highway 90) head North on State Highway 90 for approximately 6.3 miles. Turn left onto Upper Janes Creek Rd. Travel for 0.10 and turn left onto Canon/Canyon Street. The parking area is located at the end of the street.

Hunting is prohibited at this natural area.

In addition to the natural significance of the area, the property contains important historical features including several springs, for which the town of Ravenden Springs was named, and several caves/bluff overhangs that were used by early residents. One such cave "School Cave" has been documented by several secondary sources as the site of Arkansas's first free school, founded in the early 1800s.
