The Coffee Mill Hammock Formation is a geologic formation in Florida. The formation is 3-6 feet thick and is composed of shell marl. It sits on top of the Fort Thompson Formation and preserves fossils from the Late Pleistocene,[1] predominantly Chione elevata. It can be seen at Goodno's Landing, Fort Thompson, and at Coffee Mill Hammock, 12 north of LaBelle, Florida, in Glades County.[2]
