Crinoids at Hartington

Stephen K Donovan (The Netherlands) Much of the secondary railway route in Derbyshire, from Buxton south to Ashbourne, was closed in the 1950s and 1960s. Today, only the northern section is still in use as a railway, providing a route for major limestone quarry traffic (Roberts and Emerson, 2018). But the remainder of the line, from about 2.25km north of the closed Hurdlow station (Rimmer, 1998, p. 102), all the way to Ashbourne – a distance of about 27.5km – is now open as a cycle path called the Tissington Trail. This is part of the High Peak Trail north of High Peak Junction, which is south of Parsley Hay, and provides excellent access. For a map, see http://www.peakdistrict.gov.uk/__data/assets/pdf_file/0009/90486/hptisstrails.pdf. The interest of this route for the geologist is that most of it is through the Carboniferous limestones (Mississippian) of the Derbyshire plateau. The beauty of the scenery combines with the accessibility of exposures in railway cuttings to provide much of interest to the geologist on foot or bicycle. The northern part of the route, from south of the site of Hurdlow station, through Parsley Hay (with cycle hire and a cafe) to Hartington, is described in a brief field guide by Simpson (1982, pp. 102-107). My interest in these limestones is for their fossil crinoids. These are commonly difficult to see in the massive beds of limestone, which, over many years, have developed a surface patina that conceals internal features such as fossils. As this is a national park, there … Read More
