Original Caption Released with Image:

This mosaic comprises about 50 red-, green-, and violet-filter Viking Orbiter images, mosaiced in an orthographic projection at a scale of 1 km/pixel. The images were acquired in 1980 during late northern summer on Mars. The mosaic covers the region from latitude -70 degrees to 50 degrees and longitude 260 degrees to 360 degrees. The bright white region near the bottom of the image is due to carbon dioxide frost in the Hellas impact basin, which is about 2000 km in diameter. The bright yellow region at top is the Arabia region of Mars.
