Exactly which is the rock Baxter called "Prometheus" is difficult to tell, for there are several groups of rocks that  become covered with sand for even years at a time before being exposed again at the wild hands of an ocean storm, or the bursting flood of water down the river during heavy rain. This rock however is more resilient than the others. It sits closer to the water at the entrance to the bay and is less likely to be buried by sand and more likely to grow barnacles.

The rock limbs of Prometheus
Lie twisted at the entrance to the bay
Like corroded Iron......

Kelp - bladders, tangled thrown
up by the cannibal sea

And the rock of barren friendship, has another shape....

Despair is the only gift;
When it is shared, it becomes a different thing; like rock, like
water.....

Tears from faces of stone.
