Sep 17, 2003 · This image from NASA's Mars Global Surveyor highlights a Cydonia landform popularly known as the 'D&M Pyramid' on Mars. Much of the landform is covered with eroded mantling material.

The two pictures (one annotated, the other not) are mosaics of two images from MGS MOC and one from the Mars Odyssey Thermal Emission Imaging System visible camera (THEMIS VIS). The mosaics highlight a Cydonia landform popularly known as the "D&M Pyramid." It is located near 40.7°N, 9.6°W.

In his public lectures, he shows slides illustrating dozens of triangles formed by taking various points in the Cydonia region as vertices and also listing various numerical relationships involving ratios of angles from the D&M Pyramid.

David Myers (of the Mars Mission) and I surveyed the Avebury pyramid on the rim of the rampart in December 1991. This has, obviously, been considerably eroded over a period of nearly 5,000 years, and must once have been a still more impressive feature.
