5a..
Area of sidescan-sonar mosaic showing digitate pattern of broad,
shallow depressions floored by medium to coarse sand.

Boundaries of linear depressions tend to become less pronounced
in the southwest region of the mosaic where they are covered with
a veneer of finer sediment.

Area of sidescan-sonar mosaic north of the Farallon Islands consisting
of fine, medium and coarse sands.

5d. High-backscatter
features located near the continental slope west of the Farallon
Islands. The very coarse texture and high-backscatter energy is
likely to indicate outcropping bedrock. Digitate depression features
can be seen in the west region of the figure.
