Panshanger Country Park 

This used to be a gravel pit, but is now being turned into a country park.
Phase 1 opened to the public in 2014. It is a very interesting place to visit 
not only for geology enthusiasts but also for  anyone who wants to visit 
a lovely outdoors environment free of charge.

For geologists, have a look at the links below before you go along.  
The first poster explains how the deposits came to be there and how 
the Proto-Thames formed the geomorphology of the local area.  

The second poster is about the history of the chalk deposits in the area.  
It was designed to be placed in front of the chalk pit near one of the lakes.
Chalk extracted from Panshanger was used with gravel for surfacing
paths on the estate around 1880.
