It is fossiliferous in discrete bands and is commonly associated with landslides throughout Derbyshire. <\/p>\n\n\n\n<p>Alluvial deposits present in a flattened area at the bottom of the slope are associated with the Bradbourne Brook.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Landslide<\/h2>\n\n\n\n<p>Fresh landslide features known as <a href=\"https:\/\/www.bgs.ac.uk\/discovering-geology\/earth-hazards\/landslides\/how-to-classify-a-landslide\/#flows\">mud flows<\/a> were mostly seen in the upper part of the slope, below the road.
