When you select an individual excavation unit, the map will take you to a new page with summary information and panel links to specific units defined for that context. Once you select a unit, you can browse various categories of available information.
The map tools allow you to toggle between two different versions of Salmon Pueblo: the initial Chaco occupation and the later San Juan occupation. The Chaco map will provide access only to those units which date to the Chaco era (1090-1125 CE). The San Juan map will return all units defined for that context (both Chacoan and post-Chacoan).
