(a) The Department of Parks, Recreation and Tourism shall identify the protected mountain ridge crests in each county by showing them on a map or drawing, describing them in a document, or any combination thereof. These maps, drawings, or documents shall identify the protected mountain ridges as defined in SECTION 48-49-30 and such other mountain ridges as any county may request, and shall specify those protected mountain ridges that serve as all or part of the boundary line between two counties. By January 1, 1985, the map, drawing, or document tentatively identifying the protected mountain ridge crests of each county must be filed with the governing body of that county, with the municipal governing body of each municipality that requests it, and with the register of deeds or the clerk of court in the county where the land lies, and made available for inspection at the Department's offices in Columbia.
(b) Determinations by the Department of elevations under this section are conclusive in the absence of fraud.
