Mars - Mars Global Surveyor
Oblique view of Olympus Mons on Mars
This oblique view of Olympus Mons was taken by the Mars Global Surveyor
wide angle camera in the morning of local winter. The caldera measures
66 x 83 km and the volcano is roughly 550 km from top to bottom of the
image (east to west). The volcano rises some 25 km above the surrounding
region. The clouds at the top of the image cover most of the plains east
of the volcano and come up to the eastern edge of the edifice. The slopes
of the volcano are very gentle, rising 2 to 5 degrees. The image is
centered at approximately 18 N, 133 W, north is to the left and east is up.
The color contrast has been enhanced to highlight features in the image.
