Location of Robert Island in the South Shetland Islands.
Risopatrón Base, also Luis Risopatrón Base, is a small Chilean Antarctic research base in the northwest of Robert Island in the South Shetland Islands, Antarctica situated on the isthmus linking Coppermine Peninsula to Alfatar Peninsula and bounded by Carlota Cove to the north and Coppermine Cove to the south. Established as a refuge in 1949 and opened as a base in 1954, the facility supports summer research in geology, geophysics and terrestrial biology.
