| $150.00 | Leverett--Frank | Map-of-the-Pensacola-Sea-in-Florida | Original 1931 geological map of Florida showing the extent of the so-called "Pensacola Sea," prepared for the Florida State Geological Survey under State Geologist Herman Gunter and drawn by glacial geologist Frank Leverett. Issued as a folding plate from Bulletin No. 7, The Pensacola Terrace and Associated Beaches and Bars in Florida, the sheet covers the entire state by counties, with coastal lowlands along the Gulf of Mexico and Atlantic Ocean shaded in blue to indicate areas thought to have been drowned during a late Pleistocene high stand of sea level, the Pensacola stage approximately 75,000 to 125,000 years ago.

Printed at a scale of 1:1,615,680, the map includes county boundaries, major rivers, and principal towns. As an early statewide synthesis of old beaches, Leverett's map documents how Florida geologists in the 1930s interpreted ancient shorelines and coastal plains, linking modern settlement patterns to former shorelines now stranded well above present sea level.
