Carved stone post by the A413, in parish of Chalfont St Peter (Chiltern District), Gravel Hill; 50m South of junction with Copthall Lane, beside drive to Azania, within an ivy covered bank under ragged hedge, behind footpath, on East side of road. Amersham limestone square, erected by the Wendover & Oak Lane turnpike trust in the 18th century. Inscription reads:- LONDON 21 CHALFONT ST PETER Buckinghamshire HER. HER Number: 1420300000 https://www.heritagegateway.org.uk/Gateway/Results_Single.aspx?uid=MBC32751&resourceID=1024 Milestone Society National ID: BU_LC21

Two roads leave the A413 at this point climbing up the valley side to the north and east respectively.

Curiously the current Ordnance Survey 1:50,000 scale mapping has the footpath approaching the footbridge from the west then terminating at it. In practice it continues eastwards up to Gravel Hill, as shown by the sign.

The Misbourne is a classic chalk stream that was threatened in the 20th century by low flow conditions caused by a number of different human activities. Please see Image for an explanation and further links. The River Misbourne eventually drains into the River Colne near Denham in Image

According to the Highway Code the road sign on the left warns of a "Level crossing with barrier or gate ahead", and given its juxtaposition on the page with the sign with a steam engine on it warning of a "Level crossing without barrier or gate ahead" the implication is that we are coming up to a railway here. You would have to walk an awful long distance along the South Bucks Way from here to find the next railway level crossing! Anyway the sign is on the minor road between the River Misbourne on the right and Chalfont St Peter Football Club's ground on the left.
