HER Number:MDV106846
Name:Streamworks west of Challacombe Down

Summary

Medieval or later streamworks in the upper reaches of the West Webburn Valley, west of Challacombe Down. Amorphous waste heaps, pits and diggings and a small area of more regular linear banks recorded in 1990 survey. Also present is a scattered and isolated group of ten subcircular and oval waste mounds, up to 8 metres in diameter and 0.9 metres high. It is thought the streamworks may have been worked as late as the 1920s and 1930s.

Pattison, P., 1990, Field investigation, Site visit: 15/06/1990 (Report - Survey). SDV356547.

SX 68438000. Tin streamworking in the upper reaches of the West Webburn valley west of Challacombe Down from SX 68857873, where the river forks into western and eastern branches, extending north up the valley floor into the area of intensive 19th century mining in the Golden Dagger and Birch Tor/Vitifer areas. This report concerns the western arm of the river in the area known as the Redwater Valley. For the eastern arm see related monument record.
Field investigation of Challacombe Farm confined observations to the lower end of the streamworks in a triangular area of marsh centred SX 689789 close to the branching of the river. Amorphous waste heaps, pits and diggings can be seen close to both branches of the river and there is a small area of more regular linear banks and channels at SX 690790. Centred SX 68837904 is a scattered and isolated group of ten subcircular and oval waste mounds, up to 8.0 metres in diameter and 0.9 metres high.

The bed of the West Webburn River has been extensively worked for alluvial tin from where the river enters Challacombe farm on the north to where it leaves on the south-west. The streamworking consist of irregular stony spoil heaps, excavations and, occaionally, linear mounds and channels. Between Hamel Down and Challacombe Down the valley has been artificially deepened and widened because the tin-bearing lower slopes have been cut away creating steep scarps several metres high.
