Everglades Marl, Muck Peat & Limestone Rock Plain

Dominant Soil Order: Histosols / Entisols
Parent Material: Organic Muck and Peat over Marl and Miami Oolitic Limestone, with Quaternary Coastal Sand Ridges

South Florida's Everglades edge is peat and marl over limestone, and the surface is a fight with water. SSURGO mapping shows Histosols (Okeelanta, Dorovan) and Entisols (Pennsuco, Biscayne) across Miami-Dade, Broward, Palm Beach, and Glades. Organic muck compresses under load and has little bearing strength for heavy equipment. Water tables sit at or near the surface for much of the year, so excavation below grade fills with water and open cuts cave without side support. Oolitic limestone and rock outcrop sit within a few feet in places, so footings and utility lines meet hard rock. Marl is soft and wet when opened, and water sets the working schedule on these soils. Organic soil saturates in the wet season, so surface water pools in low spots and trench bottoms stay soft. Muck is weak in shear, so the sides of an open cut slump when wet.
