Puzzle Directions: Click on a puzzle piece and drag it where you want it. When you connect two pieces correctly, they will join together. This is an extra hard double-sided puzzle. The same map is printed on both sides the pieces. Some of the pieces are turned over to the wrong side. To flip a piece over, hold down the "T" key and click on the puzzle piece. Mix up the pieces again. View finished map in pop-up window.
Title: Configuration and Altitudes of the Top Eocene Limestones Projection: Unknown Source Bounding Coordinates: W: -81.5 E: -81 N: 28.5 S: 28
Description: This map shows the configuration and altitude of the top of the Eocene limestones in Seminole County, current to 1962. "The upper part of the Eocene Series in Seminole County consist of the Lake City Limestone, the Avon Park Limestone, and the Ocala Group. Figure 4 shows contours in altitude in feet below sea level of the top of the Eocene limestones in Seminole County. The amount of casing required to case a well to the uppermost limestone formation can be determined approximately from this map if the land-surface elevation is known. The upper surface of the Eocene Limestone ranges from 75 to about 190 feet below the land surface." — Jack T. Barraclough, U. S. Geological Survey, 1962 Source: Jack T. Barraclough, U. S.
