This is the smooth, striated mud surface found on the stones in scattered places around the circle. We believe that it was created by the same process as the mud ledge f423, but in different conditions, giving different results. Within the fissure around the circle, there are areas of strong accumulation and air pockets. Within the air pockets, mud would have been able to flow freely down the face of the stones, creating this surface, rather than the rough layers of f423, which were created in areas of solid accumulation.
