The secrets of natural resources to the past, present and future will be revealed during a summer nature walk along Historic Camden Revolutionary War Site’s interpretive trail July 30. Organized by the Kershaw Conservation District, the ramble will be from 10 a.m. to 1 p.m. Walkers will see and learn what early settlers saw in the park’s landscape and natural resources. Josh Arrants, a federal biologist at Fort Jackson, will lead the walk geared toward youth and adults.
