Interesting information
Below and about 1.5 km to the north of Codden Hill can be seen Venn Quarry, where sandstone has traditionally been worked to provide stone chippings with a high skid resistance for the top surface of roads.
On the summit of Codden Hill, towards its eastern end, there is a nationally important ‘bowl barrow’ with a surrounding ditch believed to date from the Bronze Age.
A small disused quarry [SS 569297] at the western end of Codden Hill near Codden Hill Cross provides a good, accessible exposure of the Codden Hill Chert Formation – the limestone and chert of the Lower Carboniferous period that dominates the local geology.
