Cave Dale

Cave Dale (sometimes spelt Cavedale) is a dry limestone valley in the Derbyshire Peak District, England. It is located at grid reference gbm4ibx|SK149824. The northern end of the dale starts at the village of Castleton where the valley sides are almost perpendicular and over 50 metres in height. The dale rises gently after leaving Castleton for approximately 200 metres before becoming steeper culminating in fine viewpoint down the dale taking in Peveril Castle with Lose Hill behind (see picture). After the viewpoint the dale swings west and levels out with gentle gradients, becoming just a shallow depression as it peters out onto the open pastureland between Castleton and Chapel-en-le-Frith.

Cave Dale was initially formed by glacial meltwater carving a deep narrow valley in the local soluble limestone. The river then found a route underground leaving a dry valley with caverns underneath. Later on the caverns below Cave Dale collapsed making the valley even deeper and gorge-like at the northern end. The Castleton entrance to Cave Dale had a narrow natural arch as recently as 200 years ago, a relic of the roof collapse [http://www.cressbrook.co.uk/towns/castleton.php Info from www.cressbrook.co.uk.] Quotation on Natural Arch.] . The lower slopes of the dale have large amounts of scree, frost on the higher limestone cliffs having caused the rock to shatter"Rocks and Scenery of the Peak District" Pages 70 (Gives info on Scree).] . Halfway up the valley is an outcrop of basaltic lava with a few small columns"Rocks and Scenery of the Peak District" Pages 82 (Gives info on Basaltic Lava outcrop).] .A bridleway runs the entire length of the dale, part of the Limestone Way footpath which travels 80 kilometres from Castleton to Rocester in Staffordshire [http://www.ramblers.org.uk/info/paths/limestonederbyshire.html www.ramblers.org.uk] Ramblers Association page on Limestone Way.] . Cave Dale is accessed through a narrow rocky opening almost from the centre of Castleton and Peveril Castle is seen high up on the almost vertical western slopes. The Normans chose this site because the steep sides of Cave Dale gave a natural defence and good lookout.

The chambers and caves of Peak Cavern run directly below Cave Dale and any small streams in the dale quickly disappear into the ground down limestone fissures and into the caverns beneath. Mineral veins can also be seen within the limestone of the dale. The cliffs at the northern end of Cave Dale are used by rock climbers and there are several routes in the Very Severe category. There are several small caves or old lead mines within the dale's limestone walls, with one being larger than the rest with bars preventing access. Cave Dale's steep north-facing grassy slopes are damp and bryophyte-rich and are dominated by oat grass ("Trisetum flavescent") and Sheep's Fescue ("Festuca ovina"). Lesser meadow-rue ("Thalictrum minus") grows extensively on ledges in the dale [http://www.english-nature.org.uk/citation/citation_photo/1002643.pdf www.english-nature.org.uk.] Biology information.] .

At the southwestern extremity of the dale as it merges into the moorland between Castleton and Peak Forest are the remains of several old lead mines. The Hazard Mine lies at grid reference gbm4ibx|SK136812, and was one of the major mines of the area. Over 5000 tonnes of lead ore were mined and the main shaft goes down 700 feet. The Hollandtwine Mine lies 250 metres to the east. Drainage from both mines went directly into Peak Cavern."Lead Mining in the Peak District" Pages 46 & 47 (Gives information on Hollandtwine and Hazard mines).]

In 1983 Cave Dale gained notoriety through the murder of a 21 year old Manchester Polytechnic student, Susan Renhard, who had travelled to Castleton in order to take photographs for an arts project. Norman Smith, a local 17 yr old youth, was subsequently jailed for life at Nottingham Crown Court in 1984.
