Amidon Memorial Conservation Area is a 1,630-acre area located on the upper reaches of the Castor River. The forest's timber species range from mixed hardwoods to shortleaf pine to cedar glades. A granite shut-ins on the Castor River adds an interesting geologic feature. The Driscoll Tract contains two old grist mill sites that date to the mid 1800s, lending a historical flavor to the area. The area is located south of Route J, eight miles east of Fredericktown. County Road 208 fords the Castor River.
