High Topps is a high, fell area, to the west of the Lake, above the upper reaches of the Valley of the Amazon, close to Kanchenjunga and its spurs, Grey Screes and Ling Scar. It is the main location for the action in Pigeon Post and also features in The Picts and the Martyrs. One end of the Old Level is on High Topps. This old mine passes right through Ling Scar to Slater Bob's Quarry. The lower part above the Amazon River is called Greenbanks; see the map of The Lake: Greenbanks ... we were up there yesterday. High Topps ends just about there (PP7)
