These small islands, the most westerly of the southwest
group, exhibited similar general characteristics - black
coral rock shores, dense vegetation, moist. highly organic
soil, and quite large bird populations.
The islands were
essentially undisturbed by construction and other similar
activities connected with the testing operations.
