An unusually detailed, archaeo-/anthropologically informed conjectural map of the Aztec capital of Tenochtitlan, and its lacustrine hinterland of Lake Texcoco. The map shows the lake in wet season conditions, when the water was high. During dry season the water lowered, turning the lake zone into swampland and several lakelets (see maps at bottom of page).

From the Conquest period onward, the lake underwent a dramatic process of infill and drainage. Today this once formidable geographic feature has disappeared, replaced by the expanse of modern-day Mexico City (see last map on page).

Note: I've moderately color-edited the map on Photoshop, mostly to clarify the distinction between the water and the littoral elevation zone.
