Tilbury further downstream, to the east can be found. The north and south sections of the M25 orbital motorway are linked by the Queen Elizabeth II Bridge and a second crossing at the same point as the Dartford Tunnel.                                                                                                                                       The area of Epping forest is part of the green belt land that forms a ring around the conurbation of Greater London. At this area there are new developments like the new town of Harlow which was built for the pupose to take the overspill population of London in the 1950's whereas older settlements like Epping can also be found. Epping Forest has mostly been removed to make way for much needed farming and settlement. Due to its popularity there is great demand for land in this area for housing, out-of-town shopping centers and retail parks and roads. Stansted Airport is located just outside of Bishop's Stortford which is close to Epping Forest.                                                                                                                                                                                                               The original area of the forest was in the region of 100,000 acres. Now it is a smaller 6,000 acre (2,4000 hectares) tract of beautiful woodland, and it obviously a lot smaller now than its original size. The woodland is especially famous for its hornbeams and there is a conservation centre at High Beech.                                                                                                   Epping forest is owned by the corporation on London and preserved for use and enjoyment by people. It is located in North east London; it is a large crescent shaped piece of land which starts in Wansted in the south and finishes in Epping in the North. The forest is 19km (12 miles) in length and is the largest area of open space in the vicinity of London and Essex. In Epping Forest the land differs greatly. There are open areas of grassland and heath, rivers, ponds and bogs, ancient woodland. Each area supports a large range of flora and fauna, many being rare species.                                 The main part of the forest is on a strip of high land rising sharply between the valleys of the River Lea to the west and the River Roding to the east. The highest point is 117 metres (384 feet) at Ambresbury Bank Rocks and Geology of the area This is a map of Epping Forest showing the types of rock                                                                                      The flow chart shows what happens                                                                                                                to rain water when it falls on the area          A cross section of Epping Forest showing the types of rock that are at Epping Forest Sources= http://www.bchs.essex.sch.uk/subject/geography/coursework.htm Types of Rock at Loughton Brook Pebbles and Gravel These are permeable types of rock which means that they will let water through quickly. Bagshot beds (sands and clays) Bagshot beds are still permeable but not as permeable as pebbles and gravel and therefore will still let water through but slower. Claygate beds/London clay This is an impermeable surface and won’t let water pass through.
