The feature known as the "Cliff" has been photographed in 
visible-wavelength light by the Mars Odyssey’s THEMIS camera. 
This is our first look at the Cliff in its entirety since the 
Viking mission took its low-resolution scan of Cydonia in the 
1970s; the previous high-resolution image taken by the Mars 
Global Surveyor featured a black swath indicating lost data (as 
described on a previous page). 
The Cliff in context. 
Though the new Cliff image is not as detailed as the MGS 
version, it provides more context. The nearby "splash" crater 
and its ejecta apron are plainly seen, confirming the Cliff’s 
conspicuous placement: if the Cliff has existed prior to the 
impact, it should show obvious signs of damage. Since the Cliff 
appears unscathed, proponents of the Artificiality Hypothesis 
argue that it was assembled after the impact. This 
interpretation is supported by a network of shallow grooves 
extending from the eastern edge of the Cliff to the lip of the 
crater. These may be remnants of a quarry/construction site 
utilizing ejecta rubble for the Cliff’s tapered base. 
The new image casts doubt on the so-called "Tetrahedral Rim 
Pyramid." The Rim Pyramid, identified by Richard Hoagland and 
subsequently incorporated into his highly mathematical "Message 
of Cydonia," appears less-than-tetrahedral and more like a 
natural deviation in the crater lip. Regardless, lines extending 
from the center of the Tholus and through the Cliff and Rim 
Pyramid produce an angle of 19.5 degrees, a recurring motif in 
the Cydonia complex. Given the heavily weathered nature of some 
of the Mound features, perhaps the Rim Pyramid’s amorphic 
condition should come as no surprise. Close-up images may tell 
us more.

Meanwhile, Bob Harrison of Cydonia Quest has brought my 
attention to a shallow, faceted formation north of the Cliff 
that shares a startling resemblance to the Fort. Partially 
buried rectilinear "cells" adorn at least one of the formation’s 
edge. This prompts the question: if natural, shouldn’t the 
"cells" have eroded away long ago? Like the Fort, the "Cliff 
Platform" exhibits signs of eroding from the inside-out. An 
alternative to this unlikely scenario is that the Cliff Platform 
has collapsed inward, leaving small-scale peripheral detail 
relatively intact. 
Synthetic perspective imagery of the Fort reveals a sunken 
interior consistent with a structural implosion (a collapse of 
the sort thought to have deformed the eastern "chin" of the 
"Face"). The Cliff Platform may be an additional example of this 
phenomenon, implying unimaginable antiquity.
