This cache takes you on a walk through Luxulyan Valley. Though it`s now beautiful woodland, in the 19th century it was an area of intense industrial activity. The valley saw quarrying of granite, copper & tin mining, and china clay processing. Relics of this industry are still visible. There are several functioning leats, which fed water to waterwheels. The most obvious feature is the great viaduct & aqueduct, built by Joseph (Austen) Treffry between 1839 & 1842.
