One such earthen pyramid was constructed in the Florida panhandle at a site known today as the Letchworth-Love Mounds. This "mound," or more accurately "earthen pyramid," is the tallest such earthwork in Florida at over 46 feet high. Pottery collected from this site was mostly of a variety known as Weeden Island. Weeden Island pottery contains many designs and motifs which appear Mesoamerican in orign. Weeden Island pottery likely evolved from another type of pottery known as Swift Creek which was also decorated with a series of designs and symbols which several researchers have noted have a Mesoamerican-appearance.
Across the border in Georgia another huge earthen pyramid was also constructed at the same time as Letchworth. The site, known as Kolomoki Mounds, also features large collections of both Swift Creek and Weeden Island pottery. The archaeologist who recently studied the site noted in his book, Kolomoki: Settlement, Ceremony & Status in the Deep South, that Kolomoki was the most populated settlement north of Mexico during its time period. The large pyramid at Kolomoki has a base larger than a football field and rises 57 feet high.
