"...theoretical modeling of the polar wander of Mars showed that the rotation axis of Mars could have moved by as much as 70 degrees within a geologically short time period in response to the emplacement of Tharsis mass [Spada et al., 1996]. The theoretical modeling also demonstrated the crucial effects of the mantle viscosity and the thickness of the rigid lithosphere on the polar wander."
Dang. No Velikovsky?
THE TWIN TILTS OF THE SPIN AXES OF MARS AND EARTH

"According to Roche's Limit, fragmentation of a smaller approaching body would occur at about 5,500 miles from the center of Mars, which is 3,400 miles above its surface. Almost opposite to the giant Hellas Crater is the gigantic Tharsis Bulge on Mars, some 4.5 miles high and 3,200 miles broad, scar piece # 3. A diagonal drawn from the center of Tharsis through the center of Hellas should give the trajectory of Astra, as it approached Mars, only to disintegrate into explosive fragments."
