Description: We found box drains on Oak Island. Underneath the coconut husk was a layer of beach stones five feet deep. Beneath the beach stones were five finger-drains constructed of flat stones, converging into a single drain. The coconut husk worked as a barrier against sand to allow water into the drains.
