The main ridge forms an escarpment —
with streams flowing directly to the sea.

Upward-tilting granitic blocks rise —
amidst long, gentle-sloping mounds.

Massive sandstone has been compressed
–some valleys have directions controlled.

Well-rounded hills show deep coatings of soil
–developed fine sea terraces along the coast.

Streams debouch upon the plain, cut into soft
sediments – broad alluvial fans of low relief —

their forms barely more than suggested. Nine distinct
far-reaching disturbances were recorded by profound

uncomformities and numerous readjustments.
Volcanism was active during several epochs —

one of these lasted a considerable time. Descriptions
following may be applied — in general — to the whole.
