My photos for this week’s challenge Boundaries were taken on a walk along the coast. The first one shows how the sandstone rocks are being undercut at the boundary between water and land.
The second photo is looking back at the same area. Here the obvious boundary is between the beach and the cliffs. The steep valley, which is the course of a stream, provides the only access to the bay from land.
The third photo gives an impression of the grandeur of the cliffs.
