Old photograph number: A13476
Caption: Pentwyn Farm, Blaina.
Description: Pentwyn Farm, Blaina. Toe of East Pentwyn landslip. Near the toe of the East Pentwyn landslip, the debris flow, approx 15 m. in thickness (see photograph A13472) divides into 2 lobes, moving at different rates and separated by the rushy gully on the centre right. The debris flow can be divided into 2 roughly equal areas, an upper part with large 'Pennant' sandstone blocks on the surface (photograph A13472) and a lower part composed largely of Rhondda Beds material with scarce 'Pennant' sandstone debris. At the toe margin, a narrow zone of rushes indicates continual water seepage and lubrication along the sole of the lobe. The flow is advancing over head-covered undisturbed basal Llynfi Beds. A small quarry is present at the centre left.
