“From the panhandle through the central lakes district all the way to the Dry Tortugas, the Roadside Geology of Florida leads you through a world of cavernous limestone, boiling springheads and rock strata containing the remains of some of the strangest animals that ever walked the earth. A great read and guide for the amateur naturalist and professional geologist alike as well as fossil enthusiasts and students.”
