The exact size of Chunchucmil is currently being studied using aerial photography, satellite imagery, and survey transects by the Pakbeh Regional Economy Project (who have been working at Chunchucmil since the mid-1990s, under the direction of Dr. Bruce H. Dahlin). Estimates range from 25 km² for the more compact urban settlement to around 64 km² for the city and its adjoining suburbs and farmsteads.Hixson 2005.
