The site is in the Forest of Dean near Longhope in west Gloucestershire. The site is of particular importance for research of late Silurian rocks in the southern Welsh Borders region. The rock exposures show extensive and continuous section through the Lower and Upper Longhope Beds of the Ludfordian. These beds are overlain by Clifford's Mesne Sandstone. There are macrofaunas present and preserved marine micofloral assemblies.
