Hill End Pit

It was formerly managed by the Herts and Middlesex Wildlife Trust (HMWT).

In February 2016 HMWT announced that three sites, Barkway Chalk Pit, Hill End Pit and Pryor's Wood, which HMWT managed on behalf of their owner, North Hertfordshire District Council, were to return to Council management as the Trust was no longer able to meet the cost.

According to A Geological Conservation Strategy for Hertfordshire, published by the Hertfordshire RIGS Group: The site gives its name to the siliceous sponge genus Hillendia, and is the type locality of the genus, and two fossil ammonite species, Subprionocyclus hitchinensis and Subprionocyclus branneri have been described from this site after being discovered there.

[1] It is shown on the Natural England Magic map as one of the "Geological places to visit".

It is difficult to find, but the site noticeboard is visible through a gap in the hedge on the left hand side of the track.
