I am no expert on the Sonoran Desert; although I live here, and considering a majority of it exists inside of Mexico, which I have camped in about ten times, I'm familiar with the terrain. A few years ago, I did this 3d map of the PineleƱo Mountains. Then there was the paleogeographic project I teamed up with a geologist to render the creation of the Gulf of California back to 10 million years. This time, I revisit the map as an art print and an essential part of my upcoming book.
There were a lot of decisions to make during this piece. How much texture, color, include roads, walls, cities, vegetation. Maps aren't maps without bathymetry, which tells the whole story IMO, especially in the gulf where the peninsula has peeled away from the mainland and is on it's way to Alaska. My spacecraft crashed here, and my information screen was on the fritz, and the power supply was waning, so I made some paper and ink and started tracing the screen to save the information.
