| Popis: | We conducted a 14-year mark–recapture study of a population of Drymarchon couperi (Eastern Indigo Snake) inhabiting an unusual geologic region (Altamaha Grit) embedded within the Vidalia Uplands Physiographic Province of southeastern Georgia. Here, we documented regular cool-season use of refuges (ground holes, crevices) associated with aboveground sandstone outcrops. Several discrete rock outcrop sites were used throughout our study period, with individual snakes often returning to the same rock dens in successive years. We describe these habitats and discuss the significance of this discovery. |
