Horr's Island archaeological site: The Horr's Island archaeological site is a significant Archaic period archaeological site located on an island in Southwest Florida formerly known as "Horr's Island".  Horr's Island (now called "Key Marco", not to be confused with the archaeological site Key Marco) is on the south side of Marco Island in Collier County, Florida.  The site includes four mounds and a shell ring.  It has one of the oldest known mound burials in the eastern United States, dating to about 3400 radiocarbon years Before Present (BP).

Zapote Bobal: Zapote Bobal is the modern name for a pre-Columbian Maya archaeological site located south of the San Pedro Martir river in the Petén department of Guatemala.  The name "Zapote Bobal" was coined by archaeologist Ian Graham, who discovered the site in the 1970s.  It refers to the large number of Zapote Bobo ("Pachira aquatica") trees, which grow near abundant sources of water in the Petén Basin.  The site languished in archaeological obscurity until 2003, when epigrapher David Stuart connected the archaeological site of Zapote Bobal with a name repeatedly mentioned in the inscriptions of sites like Piedras Negras and Yaxchilan.  That name was the toponym Hix Witz, or "Jaguar Hill" Scholars had recognized this name for over 20 years, and its connection to a real place prompted the creation of an archaeological project at Zapote Bobal in 2003, the Proyecto Peten Noroccidente (PNO).  It is currently directed by James Fitzsimmons (Middlebury College) and Laura Gamez (University of Pittsburgh).

Charlesfort-Santa Elena Site: The Charlesfort-Santa Elena Site is an important early colonial archaeological site on Parris Island, South Carolina.
