The Tholus / Monuments Zone / Cydonia Region / Mars

Readers of Hoagland's "The Monuments of Mars" will know that the Tholus is a possible conical shaped arcology about a mile across. (Arcologies are massive self contained habitations that can house substantial populations a town or city contained in a single building). In the Hoagland & Torun geometrical alignment model of Cydonia it forms a triangle with the D&M Pyramid and the "Cliff" with internal angles progressing through 30, 60 and 90 degrees. Much of the surface of the Tholus is densely honeycombed in a ruin-like way - something it has in common with other possible Cydonia arcologies such as the D&M Pyramid. The Tholus has an unusual central peak, which has the form of a 3D geometrical shape called a Spherical Tetrahedron - if a heavily damaged one. The centre of the Tholus appears to be subsiding into the rest of the mound. This suggests the Tholus may have contained many empty spaces, as the artificial arcology model would predict. As a result of this subsidence shearing forces have created a fissure and furrow that encircles the area that is sinking. For a deeper description of the Tholus click this "stargate" µµµ
