The Pergamus Flats are a low-lying natural landmark located on New Caprica, much like Breeder's Canyon.
The topography of the Pergamus Flats consists of a series of muddy plains and grassy glades located in a basin surrounded by tree-covered plateaus. A quasi-road of mud that can support human ground vehicles runs through this region.
One of the wider rises in these flats was chosen by the Cylon occupiers and the New Caprica Police as the site for the execution by firing squad of two-hundred suspected insurgents (Precipice). This plan was ruined by several uncaptured insurgents led by Galen Tyrol who killed the Centurions, Cavil and several NCP officers using automatic weapons from a small hillock. Cally Henderson was in the crowd of suspects and freed by James Lyman, who told her to run into a grassy dell behind her where she was knocked out the line of fire by Tyrol (Exodus, Part I).
