(UK-APC) in 1957. Wood Point marks the entrance of Little Jason Lagoon to the north. Little Jason Lagoon, a near-circular lagoon sits at the head of the harbour, separated from it by a narrow peninsula. So narrow is the channel into Little Jason Lagoon that it was initially named Nogood Lagoon by DI personnel. The SGS of 1951–1952, reported that the feature is known locally as Little Jason. The name Little Jason Lagoon was approved in order to indicate the nature of the feature, and at the same time to conform with local usage. The narrow peninsula separating the lagoon from the harbour ends in Lagoon Point, first called Bluff Point by DI but renamed on a 1930

chart. On the same narrow peninsula as Lagoon Point sits The Split Pin, a twin pinnacle rock formation high, also charted by DI. Tor Point forms the east side of the entrance to Jason Harbor. The name appears to be first used on a 1930 British Admiralty chart. Diamond Peak rises to the west of the harbor.
