NASA Mars Odyssey THEMIS Image: Bumps and Humps
![]() Image Context: ![]() Context image credit: NASA/Mars Orbiter Laser Altimeter (MOLA) Team [ Find on map: Javascript version ] [ Find on map: CGI version ] These small hills/mounds in Isidis Planitia may be of volcanic origin or alternatively eroded impact craters called pedestal craters. The volcanic origin seems more likely because there appears to be structural control to these features (linear pattern). These mounds may have formed over linear dikes in the region.

Note: this THEMIS visual image has not been radiometrically nor geometrically calibrated for this preliminary release. An empirical correction has been performed to remove instrumental effects. A linear shift has been applied in the cross-track and down-track direction to approximate spacecraft and planetary motion. Fully calibrated and geometrically projected images will be released through the Planetary Data System in accordance with Project policies at a later time.
