Carrs mine is part of the phenomenal Nenthead lead-zinc mining complex high on Alston Moor in the Cumbrian North Pennines. Carrs was first recorded in 1679 and by 1750 it was one of the largest mines in the area. Stone arching in Carrs Mine From about 1800 it was taken over by the London Lead Company who already ran most of the Nenthead mines. They brought in modern techniques such as horse haulage on tram rails. In the early 20th Century it was mined for zinc by the Belgian Vieille Montagne company who introduced compressed-air rock drills.

Smallcleugh chute This is a record of a tour of the show mine guided by Peter Wilkinson, showing the superb dry-stone arching of the horse levels, the vein mineralisation, some of the mining methods, tunnels and workings large and small, timbered rises, iron rails and the shapes and beautiful colours of mineral deposits - 'the mysterious underworld of the leadminer'. There is also an introduction to other things to see at Nenthead, including the unique collection of Georgian and Victorian buildings.

Modern entrance to Carrs Mine After the tour we go beyond the show mine, to explore areas of Carrs that people don't normally get to see, including a gleaming calcite-lined 'grotto' and unprotected sumps with water pouring down to even deeper mines. We also have a quick look into some of the other mines of Nenthead, particularly Smallcleugh with its stone arching, ore chutes and air doors.

The DVD Compilation C.44 Nenthead Lead Mines, includes more 1990s exploration of Smallcelugh, together with views of Rampgill, Caplecleugh and the surface buildings. Also, MineCam Compilation M5 shows remote exploration of eleven Nenthead shafts.
