Description: A National Oceanic and Atmospheric Administration map of the Crystal Bay and entrance to the Crystal River current to 1975. This Survey chart shows all soundings expressed in feet. Navigational aids such as channel markers and buoys, and hazards such as submerged piles are also shown. Green lines included are TD (time difference) lines associated with the Loran-A navigation system. These do not extend to inland waterways as the Loran system works poorly over land. N.O.A.A. map reference: 11409-2-1977. Key to NOAA maps. PLEASE NOTE: This historical data is not to be used for navigation or navigation planning. The Florida Center for Instructional Technology (FCIT) does not assume responsibility for the improper use of these data.
