The proposed Darwin Rise of Menard (1964, 1984) failed the tests of an interior high and the patterns of guyots needed. Additionally, magnetics reveals the presence of a triangular area rather than the bilateral symmetry of a rise. Lastly, modern, multibeam bathymetry with nearly full coverage fails to reveal the presence of a fossil ridge. The hypothesis of Menard, therefore, is refuted. The multibeam bathymetry actually shows a different picture, that is, one of multiple zones of weakness through the study area. The NE-SW trend is the westward continuation of the Surveyor/Mendocino fracture zone swarm to the trench
