This ecoregion occurs at the upper elevations of the interior portion of Hall Peninsula on southern Baffin Island. The mean annual temperature is approximately -11.5°C with a summer mean of 1°C and a winter mean of -22.5°C. The mean annual precipitation ranges 300-500 mm. This ecoregion is classified as having a mid-arctic ecoclimate. Vegetation is discontinuous, and dominated by such low shrub tundra vegetation as purple saxifrage, Dryas spp., and arctic willow. The ecoregion's general physiographic aspect is one of a broad, gently warped, old erosion surface etched by erosion along joint systems and areas of weakness. The ecoregion reaches about 1160 m asl and slopes southward and eastward towards the Labrador Sea. Its dissected, steep-sided, glacier-filled valleys and hummocky surface are sparsely covered by sandy glacial till. Bedrock outcrops are common, and Turbic Cryosols are the dominant soils in the ecoregion. Permafrost is deep and continuous with low ice content. The ecoregion supports low populations of terrestrial mammals, including arctic hare, arctic fox, arctic wolf, and caribou. Representative birds include the king eider, rock ptarmigan, northern fulmar, plover, hoary redpoll, and snow bunting.
This ecoregion is part of the Northern Arctic ecozone.
