## Physical geography

### Geological development

Geologically, Evans County lies in the coastal plain region of Georgia, an area consisting mostly of sedimentary rocks. The coastal plain is divided from the Piedmont by the Fall Line, which passes through Georgia from Augusta, Georgia, in the east, then southwestward to Macon, Georgia, then to Columbus, Georgia, and finally westward to Montgomery, Alabama.

Outcrops of sandstone and claystone from the Neogene era, and known as Neogene undifferentiated, cover 62% of the area in Evans County. The Neogene era has lasted approximately 23 million years, beginning 23.03 ± 0.05 million years ago. Sands and gravels from the Pliocene to the Pleistocene eras are the next most widespread geologic units, covering 26% of Evans County, followed by unconsolidated deposits of rock and sand in marsh and lagoonal facies, covering 10% of the area, and finally dune sand at 0.87% of the area.

### Rocks and soils

Sedimentary rocks are not the only geological features in Evans County. The county is mostly covered by thin sand and red and yellow clay. The amount of sand in the area can vary from a few inches to several feet. As in Tattnall County along the Ohoopee River, the sand in Evans County that lies along the Canoochee River is white quartz of a medium to coarse grain. There is exploitable medium-grain sand covering about 50 acres of land along the railroad above Bull Creek. The pure white sand along the Canoochee could be made into bottle glass, but is expensive to recover.

Much of Evans County is located in the Southern Coastal Plain Major Land Resource Area, with the southernmost portion of the county located in the Atlantic Coastal Flatwoods Major Land Resource Area.

### River, creeks and ponds

The major body of water in Evans County is the Canoochee River, a 108-mile-long (174 km) river in southeastern Georgia. Other bodies of water are Cypress Pond; Dyess Pond; Beasley Pond; Tippins Lake; Bernard Smith Pond; I.W. DeLoach Ponds; Big Beasley Pond; and DeLoach Pond. Creeks that flow in Evan County are Grice Creek, Billy Fork Creek, Thick Creek, Mill Branch, Barnard Mill, Rocky Branch, Scott Creek, Cedar Creek, and Dry Creek.

## Climate

Evans County has a mild climate, averaging 49.8 degrees in January and 82.7 degrees in July. The average annual rainfall is 48 inches and the county has a minimum altitude of 65 feet (20 m) above sea level and a maximum altitude of 228 feet (69 m) above sea level. The county is 1.4 times below the U.S. average in historical area-adjusted tornado activity. From 1950 to 2004, only 2 injuries have been caused by tornadoes in the county; this occurred on March 29, 1974, when an F1 tornado hit the county, causing between $5,000 and $50,000 in damages.
