Mineral surveys of the Farles Prairie and Buck Lake Roadless Areas, Florida showed little promise for the occurrence of metallic mineral or energy resources; the possibility for the occurrence of hydrocarbons, however, cannot be ruled out. The only mineral material that has been produced in the roadless areas is clayey sand used in stabilizing roads. Limestone underlies all of the two areas, but is too far from markets and under too much overburden for quarrying. Heavy minerals and phosphate are present in the two areas but are not sufficiently concentrated to be identified as resources.
