Multibeam bathymetry of the spreading axis of the Galapagos rift in the area of investigations on Leg 2.

Figure 2: Multibeam bathymetry of the spreading axis of the Galápagos rift in the area of investigations on Leg 2. Hotter colors (red) are shallower depth, and the map is shaded relief illuminated from the north to better show the seafloor shape. This swath was mapped during Leg 1 of this expedition. Most volcanic activity occurs along the crest of this ridge. This area is relatively near the center of hotspot influence, and going farther from the hotspot this ridge would turn into a valley marking the axis of spreading.
