Portions of the following information were taken from Florida Geological Survey Bulletin 66.

Baltzell Spring is located approximately 3.5 miles north of Marianna. From the intersection of US 90 and SR 166 (Jefferson Street) in Marianna, travel north for 2.6 miles on SR 166 to the Florida Caverns State park entrance. Turn west (left) into the Florida Caverns State Park and travel 1.7 miles to the boat landing on the north (right) side of the road. The spring and spring run are surrounded by private property but may be accessed by traveling 1 mile upstream from the Florida Caverns State Park boat ramp on the Chipola River. The spring run enters the river from the east.

Description – Baltzell Spring is also referred to as Bosel or Bozel Spring. The spring pool measures 75 ft north to south and 54 ft east to west. The depth of the spring over the vent measures 14.0 ft. The water is light blue-green with a slight murkiness. Limestone is exposed near the vent and a slight boil is present on the pool surface. There is an old collapsed dock on the east shore of the spring. A small spring run enters the spring pool from the north, and the combined flow from both exits to the south. The spring and its run support rich native aquatic vegetation. Baltzell Spring run flows south, then east for a total distance of approximately 800 ft (Rosenau et al., 1977), before entering the Chipola River from the east. To the east, the ground rises to approximately 12 ft above the water surface. An old house and cleared pasture are visible a short distance to the east. Land west of the spring is comprised of the river and its floodplain swamp forest. There are at least three other springs in close proximity to Baltzell Spring that maybe collectively referred to as the Baltzell Springs Group.
