An isolated ridge rimmed by a deeper channel is shown in this bathymetric image. How did this unique geologic feature form? Did the area beneath the ridge sink from the weight of the feature? Or was the channel formed by underwater currents gouging out the softer sediment around the ridge? Further geophysical exploration is necessary to understand such mysteries.
