property in Nottinghamshire geographics

Nottinghamshire, like Derbyshire and South Yorkshire, sits on extensive coal measures, up to 900 metres (3,000 feet) thick and occurring largely in the north of the county. There is an oilfield near Eakring. These are overlaid by sandstones and limestones in the west and clay in the east. The north of the county is part of the York plain. The centre and south west of the county, around Sherwood Forest, features undulating hills with ancient oak woodland. Principal rivers are the Trent, Idle, Erewash and Soar. The Trent, fed by the Soar and Erewash, and Idle, composed of many streams from Sherwood Forest, run through wide and flat valleys, merging at Misterton. The natural highest point of the county is Strawberry Bank, in Huthwaite. Nottinghamshire is sheltered by the Pennines to the west, so receives relatively low rainfall at 641-740 mm (25-29 in) annually.
