hablandodesigs links to the Mexican National Atlas, posted online by the National Autonomous University of Mexico’s Geographic Institute. Large-scale JPG scans of pages from the published volumes, slightly marred in some cases by not using de-screening during the scans. Map categories include General, Historical, Societal, Natural History, Environmental, Economics, and International Relations. En Espanol, of course, but even this gringo was able to make his way through the site and the maps. Here’s a subsection of one of the maps, showing the geology of the area around the northern Gulf of California.
