The region surrounding the Y-shaped wetland ignobly called Pulltrouser Swamp remained a populous area through the Classic period. Here you see K'axob in the context of the wetlands, the New River, and the major surrounding centers of San Estevan and Nohmul. Settlement survey research at San Estevan by Dr. Laura Levi and at Nohmul by Dr. Anne Pyburn has indicated that these two neighboring centers were even larger than is indicated on this map. Overall, this region probably supported a Late Classic population that numbered in the tens of thousands-much larger than the population living in this area today.
