ured over the vent is 43 ft (13.1 m). Water had slight cloudiness and was somewhat tannic
during the October 2001 visit. Algae and a thin layer of silt covers limestone substrate.
Bottom of pool and short spring run is sandy with limestone boulders and cracks. At low
tide, the boil is tremendous, and the current leading into the estuary is swift. There is a con-
spicuous drainage pipe dripping directly into the spring pool on the northeast side. High

approximately half way up a 1000 ft (304 m) long channel that empties into the east side of
the mouth of Spring Creek north of Rise No. 1. It also has a voluminous boil. Other spring
runs enter into the spring pool from the northeast and east. Its pool measures 150 ft (45.7
m) north to south and 120 ft (36.5 m) east to west. Its high velocity outflow rushes south-
west into the mouth of Spring Creek. Current is greatest at low tide. The water had slight
cloudiness and was somewhat tannic during the October 2001 visit. Depth over the vertical
opening in limestone from which water boils measures 75 ft (22.8 m) deep. The spring run
has a sand and clay scoured bottom with abundant limestone boulders exposed. The sur-
rounding land is brackish marsh and coastal hardwood-palm hammock. Spring Creek com-
munity borders the south side of pool.
