Bradwell Dale

bradwell sssi image Bradwell Dale and its upstream continuation, Stanlow Dale, lie along the margin of the karst area to the southeast of Castleton. Gorge incision resulted from the interruption of uniclinal shift by reef knolls. This type of gorge is unique to the Peak District in Britain. Stanlow Dale is incised into the Eyam Limestones, but the main gorge has cut down into the underlying Monsal Dale Beds between Hazlebadge Hall and Bradwell.

Namurian sediment trending escarpment theeast of Bradwell Dale, and the limestones rise gently from beneath the shales to form a dip-slope to the west. The slope flattens out at an altitude of between 396m and 427m OD, and it is predominantly this dip-slope, together with a small area of the Namurian sediments, which is drained by the Bagshawe Resurgence. The catchment is a large one, covering an area of approximately 13.5km2, of which 11km2 is limestone, and 2.5km2 is occupied by the Namurian rocks. The catchment area boundaries are often poorly defined, especially to the south in the region of the Hucklow Edge Vein, and to the west in the region of Dirtlow Rake. Water tracing experiments have shown that some sinks that are topographically within adjacent SSSI drain to the Bagshawe Resurgence as well as to springs in the other SSSI.
