<underground_description>Originally thought to be a choked shaft, it was noted as "worth another look" in 1987, but was not relocated in 1988. Closer inspection with a ladder revealed parallel slots in the rift and a noticeable draught.</p><p>The original entrance is a "walk-in" open shaft which leads on to a twisted vertical pitch of 17m, <b>Parthos</b>, into a sizeable chamber at the top of a rubble slope. The obvious small wriggle at the bottom of the slope leads to the <b>Musketeers' Series</b>, while a bolted climb leads to the main way on.</p><p>The Musketeers' Series consists of stooping phreatic passages, with a 5m pitch, then a couple of climbs to the head of an 11m pitch, <b>Aramis</b>, into a chamber. At the far end, a further pitch, <b>Athos</b>, is 8m. The way on is up a short climb to the head of a 5m+10m ramp, <b>Porthos</b>, down to a phreatic tube with a silted up floor. Digging in the silt revealed a tight rift rising up, but as this was too tight, the dig was abandoned. The water from Aramis descends a tight rift in the base of the phreatic tube, but after 3m, this too became too tight.</p><p>The climb up before the Musketeers' Series leads quickly to a T-junction. To the right, a winding ramp passage of decreasing size leads on and up with several fallen blocks making progress awkward. This route ends at a small chamber with an inlet dropping from the roof. Left from the T-junction leads on down a gently sloping boulder ramp in stooping, then walking passage. This increases in size and becomes steeper before emerging into the side of an enormous boulder ramp, <b>Hillsborough Revisited</b>. The inlet passage enters three quarters of the way up Hillsborough, which is 10m wide by 5m high and drops a total of 40m at 40°. At the base of Hillsborough, an aven rises to the surface and daylight can be seen reflecting off the sides of this second entrance. A third entrance was discovered on the surface which leads down a deep grike through a tight arch and into a small chamber. Digging boulders revealed a steeply inclined squeeze leading onto a pitch at the top of the Hillsborough ramp. The base of this pitch leads onto an inclined overhanging terrace with a hole at the back which drops 2m onto another inclined overhanging terrace. A 4m climb down from this ledge ends at the top of the boulder ramp of Hillsborough.</p><p>The base of Hillsborough was blind until a dig in unstable boulders on the left hand side revealed a tight drop between two wedged boulders into another very sizeable ramp, <b>Penistone Road</b>. This ramp is convoluted and twists around open shafts and roof collapse to end in a huge chamber with a small muddy hole in the floor, <b>The Hole in the Road</b>. This way on is blind.</p><p>An alternative route from the main ramp of Penistone Road leads down an old phreatic tube decorated with calcite frost and numerous small helictites to a flat-out crawl to a 25m blind pitch.</p><p>Near the bottom of the Hole in the Road, a 6m rope climb up the eastern wall, <b>The Escalator</b>, leads to a series of solution tubes. A 1m diameter tube drops NE into <b>The Broadwalk</b>, a sizeable mud-floored phreatic passage. Here, following a strong draught, the passage opens up, becoming very high with a number of avens cutting down into the passage. A 4m rope climb drops down to the head of a pitch, <b>Reason to Believe?</b>. This dry shaft is disjointed and 144m deep, broken at approximately half depth by a 'saddle'. A further short pitch lands on a slope before the final drop into a sizeable chamber. The only exit from this chamber is to the east and is a muddy rift passage traversed at various levels. This leads to the head of a further series of disjointed shafts and the wet 77m pitch <b>More than a Feeling</b>. Here a 57m drop lands on a spray-lashed ledge and a further 20m drop gives way to a large boulder slope. Two wet 2m climbs lead up to the head of a 7m pitch which leads to the base of the shaft.</p><p>Through the small passage across the base of the shaft, a climb down thro
