Duckburg is a major center for Space exploration, mainly operated and overseen by Gyro Gearloose, and has had expeditions to the Moon, Mars, Venus, the Asteroids, and more remote parts of the Galaxy. The city also features a sea port and is in proximity of a large forest called the Black Forest and to several mountains, the most notable being "Old Demon Tooth", usually depicted as a towering pointed peak leaning slightly to the side. The main river of the city is the Tulebug River, first mentioned in "The Money Well" (1958) by Carl Barks, and it is located near Killmotor Hill.
