Marco Gonzalez is a Maya archaeological site located near the southern tip of Ambergris Caye off the coast of Belize. It was first recorded in 1984 by Drs. Elizabeth Graham and David Pendergast, and was named by them after their local guide.

Rapid rising in sea levels caused by the melting of the last Pleistocene glaciers caused the geography of the coastal area around Marco Gonzalez to change. As sea levels rose, the coastline shifted to shelter the surrounding area from currents, allowing mangrove swamps to completely surround the site. Eventually, the encroachment of the surrounding jungle and swamplands made the site inhospitable, and the Maya abandoned it.
The discovery of artefacts below present sea level, and beneath the mangrove peats, indicated that the habitable area of the site was much larger in the past than now; and subsequently that the inhabitants moved to progressively higher ground as sea level rose and the swamps encroached upon them. http://en.wikipedia.org/wiki/Marco_Gonzalezhttp://www.marcogonzalezmayasite.com/ http://ambergriscaye.com/marcogonzales/index.html
