The challenge was to map a desert. I thought it would be funny to try out my watercolor pencils. I did not use watercolor paper, which is something to improve in the future. I also made a map I could potentially use with the Call of Cthulhu role-playing game's Down Darker Trails supplement for the American Wild West setting. It provides a link between Devil's Gulch (a Weird West town setting written for Chaosium's Basic Role-Playing system, of which Call of Cthulhu is a variant) and El Canon de Los Viejos, the Down Darker Trails dinosaur-having "lost world" sub-setting, while at the same time providing numerous adventure possibilities within its own confines.
