It looks like an alluvial layer of sand and sediments that got stuck together with probably silica(quartz) or calcite since the 'cement' is clear or colorless.
Here's that link again if you want to read about Sandstone in Florida.

Wear goggles or some sort of eye protection before you start beating on any rock with a chisel and hammer. Gloves are a good idea, too.
