Roundness is the degree of smoothing due to abrasion of sedimentary particles. It is expressed as the ratio of the average radius of curvature of the edges or corners to the radius of curvature of the maximum inscribed sphere.
The sphericity of a particle is: the ratio of the surface area of a sphere (with the same volume as the given particle) to the surface area of the particle. |

Lighthouse Inlet Heritage Preserve is located at the northeastern terminus of Folly Island and adjacent to Cummings Point. Lighthouse Inlet Heritage Preserve played a significant role in the Civil War and was also used throughout the twentieth century by the US Coast Guard. It is the perfect spot for viewing the Morris Island Lighthouse, surf fishing, beachside strolls, wildlife observation, and photography. The site also offers many diverse birding opportunities and is a regular site for organized bird walks. Sally Tucker photograph and caption
