Map highlighting the dense gravitational structures in the northern hemisphere. The regions denoted by the black lines are high mass anomalies that do not show any correlation with geology and topography. These hidden subsurface structures are covered by sediments from an old ocean. Their origin is still a mystery and a dedicated gravity mission, like MaQuIs, is needed to reveal their nature.
