LIMA presents the first-ever, true-color, high-resolution view of Antarctica. Prepared from 1100 Landsat-7 images collected from 1999 to 2003, it provides scientists and non-scientists a stunning "you are there" view of the least familiar continent. Shown here are two perspectives of Byrd Glacier, one of the largest in Antarctica. The down-glacier view (above) looks northeastward and the up-glacier regional view (below) looks southward toward the South Pole which is 1050 km distant. The 15-meter resolution imagery is draped over the Radarsat Antarctic Mapping Project Digital Elevation Model Version 2.

Byrd Glacier plunges through a deep valley in the Transatlantic Mountains and onto the Ross Ice Shelf, dropping more than 4,300 feet over a distance of 112 miles. It remains a distinct ice stream all the way to the edge of the shelf, some 260 miles from the foot of the mountains to the open sea.

This cross image of the slow-moving Darwin Glacier in the foreground and the faster-moving Byrd Glacier in the background as both glaciers approach the East Antarctic Ice Sheet. A 2x vertical exaggeration has been applied to the topography.

The glacial ice has a blue cast and bears long stripes that echo the currents in a river. The current in this ice stream carries more ice to the Ross Ice Shelf than any other ice stream. A 4x vertical exaggeration has been applied to the topography.
