Antarctic volcanoes, satellite image

Antarctic volcanoes, satellite image. North is at left. This chain of five volcanoes (the Executive Committee Range) is part of a larger chain of 18 major volcanoes stretching for 900 kilometres along Antarctica's Pacific coast. From left to right, these five volcanoes are: Mount Hampton (3323 metres, lower left), Mount Cumming (2612 metres), Mount Hartigan (2800 metres), Mount Sidley (4285 metres, dark shadow in summit crater at upper right), and Mount Waesche (3292 metres, furthest right). Mount Cumming and Mount Hartigan (both at centre left) are smaller and less visible than the other three volcanoes. Mount Sidley is the highest volcano in Antarctica, with a summit caldera 5 kilometres across. This image covers an area 125 kilometres across. Image data (combining infrared and visible light) obtained on 20 November 2014, by the OLI (Operational Land Imager) sensor on the Landsat 8 satellite.
