A detailed bathymetric survey of the crest and axial valley of the Gorda Rise, between 41°10' to 41° 29'N and 127°15' to 127°36'W, has revealed several pronounced continuous benches. The most prominent benches are at depths of 2400 and 2800 m. The regional bathymetry is consistent with a block-faulting origin for the topography of the Gorda Rise.
