HMS Colossus: debris field survey 2004
Wessex Archaeology survey

Wessex Archaeology, the current archaeological diving contractor, spent three weeks this year diving on Colossus and the associated debris field. A plan of their search areas, constructed from information given to me by them, is reproduced below. It is clear from this plan that a considerable area of the debris field was investigated by them this year. When their report of this work is available it should be possible to integrate their findings with those presented here. As far as I am aware their findings consisted mainly of a copper alloy fastening pin (WA 260167.3E 5535629.2N) and an iron gun (WA 260211.9E 5535542.5N), possibly our Gun 10 – see discussion of CISMAS target 16/2035 below.
