Rising Brook 12 is another misfit river, dwarfed by its ad M o utc R h 20 y ill’s deeply-incised valley 13, possibly cut by the draining of a glacially-dammed lake. Triassic le Gutter ge u rocks were deposited unconformably on top of deformed Carboniferous mudstones and coals R To (see cross-sections). Colliery Road 14 runs Red Brook above the unconformity which can be recogn- Hazelslade

ised on the trail 15 by the change from drier, peb- 16 BS bly conditions to wetter and muddier ones. The Old Park Coal outcrops just beyond Red Brook 16 19

and numerous small bell pits were dug here. Circu- CM MM lar depressions near the trail mark some of these. 17 18 CASTLE RING Ironstone was also extracted and smelted locally us- KF ing charcoal. Orange sandstone breccia, the Hopwas P PH Formation, occurs in a metre high section to the left of the HB d ill R Cannock H trail at the base of the Triassic 17. Below this, the Castle lly 13 Meltwater channel o Wood Ring Coal was extracted to the north of Castle Ring. H Castle Ring - Slitting Mill 18-32 The view from Castle Ring 18 shows the low ground beyond Rugeley formed by the soft Mercia Mudstone rocks of the Needwood Basin with the Peak District beyond. The trail between 19 and 29 follows the Eastern Boundary Fault, responsible for bringing the coal close enough to the surface to be mined. At 19 the higher ground marks the Bromsgrove Sandstone across the fault. The Kidder- minster Formation forms the ridge between 20 and 21. At 22 coal fragments are visible in the muddy track and bell-pit depressions occur near by. Pebbles return as the fault is crossed and the track be- comes sandier as it passes into the Bromsgrove Sandstone 23. The stream here is red-orange from the leaching of ironstones within the coal spoil tip which can be examined at 24, the site of the Old Engine Pit. The Eastern Boundary Fault can be seen at 25 with downthrown Bromsgrove Sandstone nearest the road and Kidderminster Formation behind. The latter unit can be seen in the quarry 26. The track from 24 to 27, 28 & 29 is the old colliery railway. The Levels and Belfast Pits were near 27 Iron stained stream 23 and the Coppice Pit at 28. From 29, the view is from the high ground of the Kidderminster Forma- tion across to the lower ground of the Mercia Mudstone beyond the boundary fault. The trail from 30 to 32 re-crosses the misfit Rising Brook31 valley. Compare the valley profile to that at 13. The far valley edge is a fault with Bromsgrove Sandstone 32. The escarpment at 34 also marks the fault.
