The Chatham Sound is a broad body of water off the northwest coast of Prince Rupert.1 It resides between Digby Island and Dundas Island and was named by Captain Charles Duncan after John Pitt, the 2nd Earl of Chatham
and the 1st Lord of the British Admiralty.2Captain Pike, while working to control illegal liquor trading in Fort Rupert, travelled through Chatham Sound in 1863.4 The lighthouse on one of the islands in Chatham Sound is the most northerly light on the coast.5
