Abstract
Results are discussed of a bathymetric survey of 250 sq mi in the area of Erben Guyot, a volcanic feature 800 mi west of San Diego, Calif., adjacent to the Murray fracture zone. The guyot has an overall conical form about 2,200 fathoms high; its top is a 4.6 mi platform at depths from 300-500 fathoms. In places slopes are as great as 45 degrees and are probably bedded lava flows and volcanic debris. Two other peaks on the flanks appear to be volcanic vents or fissures. A bathymetric chart and a profile of the guyot are included.
