Field notes
What the tide leaves behind
At low water the rock shelf turns into a hundred small rooms. Anemones close to keep wet, crabs back into the shade, and the limpets clamp down and wait for the sea.
Stay still long enough and the pools start moving again: a shrimp, a goby, the slow unfolding of something you took for a stone.
The best hour is the one before the turn, when the light is low and the water is clear enough to read the bottom.
