Perfect
Crater is the only crater on the island with a complete rim. It comes
from the third phase of volcanic activity.

All of the other craters are "breached", that is to say their sides have been partly broken down by the lava. This was due to the south-east trade wind causing a build-up on the leeward side, so that later lava flows were forced to break out on the leeward side. |
