1970 Map of South Of Holley

About this map

Santa Rosa Island stretches across this 1970 coastal survey, serving as a narrow barrier between the sheltered waters of Santa Rosa Sound and the open Gulf of Mexico. The landscape is defined by its shifting coastal elements, including prominent sand dunes and a significant tidal flat that highlights the dynamic nature of the Florida shoreline at this time. This sheet is particularly interesting for its focus on the physical hydrography and the natural boundary between Santa Rosa Co and Escambia Co, providing a clear record of the undeveloped coastline and bathymetric soundings before significant modern shifts in beach morphology. The focus remains on the intersection of land and sea, documenting the precise contours of the barrier island system.
