The Flickr Orsonwellescrater Image Generatr

Today's VIS image shows part of the floor of Orson Welles Crater. This region of the crater contains chaos. Chaos is formed where tectonic forces break the surface into blocks. Erosion along the breaks widen and deepen the valleys between creating mesas. There is evidence that this crater may once have held a lake. Orson Welles Crater is 116 km in diameter (72 miles).

This martian scene spans 18 x 273 kilometers (11 x170 miles). To see where on Mars this area lies, and to download high-resolution versions of the image go to themis.asu.edu/zoom-20231120a

Photograph inverted from "usual" presentation in order to have North at top.

The photograph basically spans between Ganges Mensa and the crater Orson Welles.

Edited Mars Reconnaissance Orbiter image of light-toned deposits in Orson Welles Crater.

Edited Mars Reconnaissance Orbiter image of a tilted block of terrain set in a general subsidence south of Orson Wells Crater on Mars.

Surrealistic and stunning Viking Orbiter 1 photo featuring a myriad of exotic Martian land-forms and features - imaged roughly FORTY (40) years ago...AMAZING!!! North is to the upper right. 8" x 8".
Compare/contrast with the Fobos 2 thermal image at: mentallandscape.com/V_Cameras.htm.

Impact crater Orson Welles (incorporated into Shalbatana Vallis), Xanthe Terra region, Coprates quadrangle. Ganges Mensa and Ganges Chasma are visible at the bottom of the photograph. North is roughly along the path of Shalbatana Vallis as it traces toward the upper right. Other features visible include Camichel crater, Nanedi Valles/Vallis and Aromatum Chaos.
