View from Salthill quarry, Clitheroe. The photo above shows the relationship of geology to topography. Pendle Hill is capped by the resistant Pendle Grit Formation (the type section being in Little Mearley Clough (SSSI) - the main gully in the centre of the photograph).
Below the Pendle Grit lies the Upper Bowland Shale Formation depicted by the steep gullies on the hillside. The resistant Pendleside Sandstone marks the change in slope and transition into the Lower Bowland Shale Formation. Pendle Hill falls away abruptly to the left of the photograph above. This was probably due to the intense erosion by the Ribblesdale Ice Sheet.
