“…However, several studies have shown that resources in the Maya lowlands are not as evenly dispersed as once thought (Dunning et al 1998;Fedick 1996;gomez Pompa et al 2003;McAnany 1993). Lowland resources such as salt (A. P. Andrews 1983;McKillop 2002), chert (Potter and King 1995;Shafer and Hester 1983), and cacao (McAnany et al 2002) are famously patchy. But even in areas without such assets, other features such as escarpments , swamp edges (Kunen 2004), karst depressions (Kepecs and Boucher 1996;Munro Stasiuk and Manahan 2010), rivers (Siemens 1996), terrace-able hills (Chase and Chase 1998), and fracture zones (Fedick et al 2000) each permit local resource specializations.…”
