First in a series of images of pebbles from Langland Bay in Gower. It is a characteristic of the beaches around Gower in South Wales that the pebbles, where they occur, are enormously varied in colour, shape, and geology. Some come from the bedrocks of the peninsula itself and others were brought from much further away by ice sheets. Although the ice never entirely covered Gower, currents and tides move pebbles around the coastline. Each tide washing in and out over the shore sifts, shifts, and redistributes the stones into momentarily unique patterns – a bit like the old-fashioned kaleidoscopic designs that I remember from childhood.
