The Natural Area Roadless Area, which is in the Osceola National Forest in Baker County, Fla., is underlain by sedimentary rocks containing phosphate deposits that are not a potential mineral resource by todays standards. The region has a low potential for oil and gas and virtually no potential for other valuable minerals. The phosphate deposits are either slightly low in tonnage and P2O5 content, high in MgO and/or Fe2O3 + Al2O3, or the ratio of CaO to P2O5 is too high for deposits that can be mined profitably at the present time. A low potential for oil and gas is indicated by the numerous dry holes in the region and the absence of the formations that contain these hydrocarbons in southern and westernmost Florida. The only mineral material that has been produced in the study area is clayey sand, used in stabilizing Forest Service roads. This type of clayey sand has no particular value because there are virtually unlimited quantities in the surrounding region. The peaty material in the area is too high in ash content to be mined. Large quantities of limestone underlie the area but are too deeply buried to be quarried. Heavy-mineral and clay deposits, which are mined elsewhere in northern peninsular Florida, are not present in the study area.
