This green space occupies part of the route of a former mineral tramway which lead from the Chaddesdon Brickworks (Now the Nottingham Road Fire Station) to the Stanley Footrill Colliery (Now a works site near Manor Farm, Stanley) and linked to the G.N.R Derbyshire Extension line on the main network (Now the Greenway Bridal path). The green was referred to locally as 'Treebase' in the 90's. The underlying rocks are of the Mercian Mudstone Formation, 216 million years ago the sediments settled in a hot evaporated lagoon before being gradually infilled buried by fine red mud. Underlying this is the Coal measures which formed as a dense swampy forest 310 million years ago. The UK relied heavily on this coal for much of it's power generation but is gradually phasing out it's use in favour of more environmentally friendly sources.
The cache is located on the raised area on the west of the green. In places the ground is slightly uneven underfoot and there are brambles in the summer months. You are looking for a plastic screw-top tube a couple of inches long. Please replace as found.
