N2 - We examine the geology of Ishtar Terra, Venus, as viewed in high-resolution Magellan synthetic-aperture radar imagery and altimetry, in order to interpret regional surface strain patterns. Ishtar straddles a long-wavelength topographic bulge that is compensated at ~130±40km depth, whereas the short-wavelength features (individual mountain belts and tesserae) are compensated at varying depths in a range of ~25-70 km. These two ranges of compensation, taken together with surface strain patterns, lead us to postulate a new model for the evolution of Ishtar Terra. -from Authors
