In an alliance with the Sonoran Institute, the National Geographic Center for Sustainable Destinations helped the region’s communities create the first transborder Geotourism MapGuide, covering northern Sonora and southern Arizona. The mapguide was published in 2007:
The maps have vignettes of information about history, culture, geology and many other aspects of the region, making it a useful guide for geo-tourists. While some might argue about the choice of locations and attractions described on the maps, this is a useful addition to the background reading for anyone thinking of traveling to this region with some time on their hands to explore.
Surprisingly, the map has only a very brief and somewhat dismissive mention of the El Pinacate and Gran Desierto de Altar Biosphere Reserve:
“Stand at the rim of this mile-wide volcanic crater and you may feel as if you’re on the moon. This land of ancient lava, sand, and cinder cones is sacred to the O’Odham people. Today, those on the Sonora side of the border call themselves “Pápago.”
