This Inch to the Mile map covers the area from Mossley and Delph eastward to Penistone, and from Honley southward to Glossop. Author David Hey describes the area, much of it part of the Dark Peak, as "a true wilderness that is transformed in summer when the purple heather is in bloom, bilberries are ripe and the rocks glint and sparkle in the sun". The Great Central Railway, with its long Woodhead Tunnel, runs through the map. In the north west is Saddleworth Moor, while the map also includes Holmfirth, made famous through Last of the Summer Wine. On the reverse they include a detailed map of Honley, including Upper and Lower Thirstin and Fisher Green. Most of the main map is Yorkshire, but there are also small sections of Cheshire, Derbyshire and Lancashire.

It is not possible to list the many hamlets, farmsteads and other topographical features shown on these maps. However, you may find it useful if we list the towns and principal villages or church parishes that are included on this map.
