Above Fox Hole Bottom on the north side of the Wylye Valley.
"The cap badge on the slope above Foxhole Bottom, made by Australian troops, 1916-17, incorporating glass beer bottle bases. Polishing the bottles became a punishment duty, giving rise to the site's colloquial name, 'Misery Hill'. Turfed over during the Second World War to prevent its use by enemy bombers, the outline was restored in chalk and last scoured in 1999 by Austrailian troops."

Nowadays these hill figures are restored with fresh chalk dug from the hillside nearby. Note the figures on either side which have partly grassed over.
