The Geyser is a tall narrow slot with an opening to the sea. As the water rushes in, air is trapped in the crack, then bursts forth up the crack in an explosion of spray. After watching the Geyser in operation for some time, it appears that there may be a link to another entrance, as the force with which the air was expelled did not always match the amount of water going in. Another explanation is that the crack is wider below water level than above.
On the other side of the inlet is a wide flat shelf, where the water runs up the entrance channel and curls onto a rock slab. Judging from the volume of water going into the entrance, there must be a passage behind the entrance.
There is a large slab in the middle of the inlet between the entrance channels to the Geyser and the Wide Shelf.
