Geological notes and local details for 1:10 000 sheet TG 32 NE (Lessingham) : part of 1:50 000 sheet 148 (North Walsham)

The following report is designed to be used in conjunction with 1 : 10 000 Geological Sheet TG 32 NE. Uncoloured copies of the map may be purchased fkom the Survey's headquarters at Keyworth. The district covered by the map is included in 1 : 50 000 Geological Sheet 148 (North Walsham). It formed part of Old Series One-Inch sheet 68 E, and was surveyed at a scale of 1 : 63 360 by C Reid in 1877-1878. The district was resurveyed at 1 : 10 000 scale by the present author in 1995, with Dr I R Basham as regional geologist. The area lies to the north-east of Norwich, and just touches the coast at Cart Gap which lies between Happisburgh to the north and Eccles on Sea to the east (Figure 1). The market town of S t a b lies on the southern border of the district, and the villages of Inghm and Lessingham lie within the eastern part of the district. The remainder of the district is rural, and includes parts of the parishes of Brumstead and East Ruston. No major rivers drain the district, but the River Ant passes just to the west; this flows southwards into the area known as the Norfolk Broads to join the Bure and ultimately drains to the sea at Great Yarmouth. The un-named steam which flows to the east of Lessingham rises just to the north-east of the district and continues southwards via the New Cut, Horsey Mere, Meadow Dyke, Heigham Sound and the River Thme to join the Bure at Thurne.
