This colour change is post depositional. Bedding within the sand indicate that the water bearing the sand ran consistently south. The sand contains frequent local concentrations of coal and black shale and very occasional gravel patches and degraded shell fragments. Within the white sand are layers of organic mud. Towards the base of the observed sections these were only 20-200mm bands of sand mixed with organic mud. The thickest (400mm) were located at the top of the section. Trunks of birch and conifers were scattered throughout the mud layers. The stump of a spruce (Picea) was found upright on the uppermost bed and was radiocarbon dated to 53,000 years BP. The succession of deposits suggests the infilling by mud and sand of shallow pools within the silica sand. Any suggestions as to Monument Type?
