Little Heath, near Hemel Hempstead, Hertfordshire

Little Heath is an well defied area of woodland with scattered housing located south of the village of Potten End, Hertfordshire in England.
It is especially distinctive because it represents the top of the Chiltern Hill plateau and has distinctive geological beds that remain while they have been eroded elsewhere. The exposed structure of ancient coastal deposition has been classified as a Site of Special Scientific Interest (SSSI) because of its unique geology. See Little Heath Pit.
The land is a detached part of the Ashridge estate and owned by the National Trust. It is thickly wooded . The woods are dotted with many deep pits called dells which are the remains of gravel extraction work during World War 1 when it was used to make sandbags. There are up market detached residences and a tea room with a small plant nursery in the area.
Two World War 2 anti tank bollards are located at the bend in Bullbeggers Lane on the south western side of the wood
