The dark and constantly-shifting interior of the Mystery Flesh Pit National Park has been a formidable challenge to navigation since its discovery. Tethered explorations early in the history of the park mitigated this problem, but more comprehensive surveys eventually required a novel solution. By using a standard magnetic compass in combination with a barometer, a directional bearing and relative depth within the organism can be obtained. Of course, these two items of information are alone insufficient and require a small assortment of other physical and chemical orienteering solutions to effectively navigate within the superorganism. Still, devices similar to the Anodyne-produced unit photographed here have been and continue to be invaluable basic tools for park rangers, engineers and technicians who need to know where they are within the park.
