Geology
The water seeping from the surrounding moorland Rake Dike is the source of the River Holme. Rake Dike rising from Kay Edge on the moor flows through the village of Holme and into Brownhill reservoir, about a mile below the moor, and passes down through the Holme Valley to Huddersfield, where it flows into the River Colne. The upper part of the moor continues into Black Hill which is crossed by the Pennine Way north–south footpath.
