Florida has a diverse wealth of geological resources.
People have enjoyed the sands of Florida’s beaches for more than 12,000 years. Prehistoric people in Florida used chert to make weapons and tools. Later indigenous people used clay to create bowls and storage containers.
Coquina rock provided a practical building material for Spanish colonists. The Castillo de San Marcos in St. Augustine was originally constructed in 1672 using coquina and the fort remains undefeated in battle.
