Maps
Gentry and Dodson put Centinela on the map, but they didn't make many maps of Centinela. We've been putting together some of the first—which show Centinela to be a much larger, more complicated landscape than the original papers implied. By one definition, the Centinela region comprises 40 square kilometers of topographically complex highlands in three 'sky islands' separate from the main body of the Andes (the area delimited by the purple lines in Map 1, below). Gentry and Dodson appear to have mostly explored a ridgeline near the settlement of Centinela del Pichincha.
