Byers Peninsula is situated at the west end of Livingston Island, the second-largest of the South Shetland Islands (Map 1). The peninsula has a central west-east extent of about 9 kilometres and a NW-SE extent of 18.2 kilometres, and is the largest ice-free area in the South Shetland Islands. The peninsula is generally of low, gently rolling relief, although there are a number of prominent hills ranging in altitude between 80–265 metres. The interior is dominated by a series of extensive platforms at altitudes of up to 105 metres, interrupted by isolated volcanic plugs such as Chester Cone (188 metres) and Cerro Negro (143 metres).
