The Ocmulgee National Monument preserves traces of over ten millennia of Southeastern Native American culture.  The park contains the site of the Great Temple Mound, a burial mound, and other ceremonial mounds. The prehistoric people chose the site of Macon, Georgia to build their amazing landmarks because it rests right on the fall line where the Piedmont meets the Atlantic Coastal Plains of Georgia.  This area of Georgia has the perfect climate for hunter-gathers and farmers. The climate also allows the indigenous peoples the perfect conditions for living.  The winters are mild and the summers are hot but not severe.  It is a central location.  Since the Great Temple Mound is located next to the Ocmulgee River, this allows people the ability to have water for drinking and crops as well as a means for transportation.  Since other means of transportation were more laborious and not efficient, the mode of transportation the river allowed to other places in Georgia greatly advanced the people living in this area.   

Twelve Soil Orders of The World

 Oxisols are soils that are very highly weathered. Oxisols are found primarily in the intertropical regions of the world. These soils contain few weatherable minerals and are often rich in Iron and aluminum oxide minerals.

Oxisols occupy ~7.5% of the global ice-free land area. In the US, they only occupy ~0.02% of the land area and are restricted to Hawaii.

Most of these soils are characterized by extremely low native fertility, resulting from very low nutrient reserves, high phosphorus retention by oxide minerals, and low cation exchange capacity (CEC). Most nutrients in Oxisol ecosystems are contained in the standing vegetation and decomposing plant material. Despite low fertility, Oxisols can be quite productive with inputs of lime and fertilizers.
Oxisols are divided into 5 suborders: Aquox, Torrox, Ustox, Perox, and Udox.
