Monte Burney is an ice-capped stratovolcano located 200 km northwest of the city of Punta Arenas and south of the Cordillera Sarmiento, on the Peninsula Muñoz Gamero, in the Chilean Patagonia. It is composed from andesite with pumice around its foot,[3] including some dacites with the overall SiO2 ranging 59-66%.[4] The volcano has a small summit crater and a steep northern wall. The eastern sections of the volcano are composed from a ringplain of Holocene pyroclastic flows with possible pre-Holocene volcanic outcrops.[5] On the northwest side of the volcano a small icecap can be found.[6] From 1870 to 2011 it shrank from 22.4 square kilometres (5,500 acres) to 15.5 square kilometres (3,800 acres) surface area.[7]

The mountain was named Mount Burney in honor of James Burney.[8]
