'To the south of the River Mersey the land rises from sea level to the Cheshire plain 50-70m higher. Erosion has produced an edge, with several steep hillsides and outcrops of the underlying red sandstone. From the valley this gives a skyline view of a ridge of low hills, often wooded. The Mersey Valley Timberland Trail follows the edge of the high land, sometimes dropping down to the valley to offer views from both levels.'
