Hartshill Diorite Pits
Early 20th Century test pits to extract diorite rock for road aggregates.
Said to date to some time prior to 1923 these small pits with spoil heaps were sunk with a prospect of quarrying diorite but the rock here was found to be badly weathered and decomposed.
Diorite is an igneous rock used in aggregates for (among other things) road construction.
