The geometric Main City Pyramid shown with comparable Viking image of the same feature (inset).

The Main City Pyramid (or "Starfish") in 2002.

Dr. Mark Carlotto's dissolve shows the Main City Pyramid increasing in resolution (from Viking to MGS). Also note the shifting angle of illumination.

The City Square, adjacent to the Main City Pyramid, next to an enlargement of a small triangular feature in the bottom-right formation.

The City Square in 2002. Note that the small triangular feature is still visible despite different illumination.

This ice-filled crater is overlooked by the Main City Pyramid's bifurcated northeast corner (see below).

Other "City" anomalies:

This large feature, dubbed the "City Mound," is located directly below the City Pyramid.

This small (Egyptian-scale) pyramid is located atop the City's southwest landmass. This photo was taken in 1998.

Released in 2001, this photo shows the "Egyptian" pyramid in significantly higher resolution.
