Summary

Medieval or later streamworks situated around the headwaters of the River Avon. An archaeological field survey in 1995 identified two extensive areas of streamworks. In an area to the north around Avon Head the streamworks are about 0.5 to 1 metre deep, and covered by or merged with blanket bogs. To the south the valleys of Fish Lake and the River Avon contain extensive streamworks covering an area of about 10 hectares, and two associated buildings a possible tinner's hut and tin mill.
