Admiralty Inlet is the waterway connecting the Strait of Juande Fuca with Puget Sound. The name was bestowed on Saturday,June 2, 1792, by Captain George Vancouver, the discoverer, in honor of the Board of Admiralty, which supervises the work of the RoyalNavy of Great Britain.
The Spaniards were first to see the waterway. Quimper saw its entrance in 1790 and Eliza examined it more carefully in 1791. He did not explore it because the Indians said canoes would be necessary to reach its farthest limits.
These Spaniards gave the entrance the name Boca de Caamano. As their maps were not published, Vancouver had no way of knowing that his name of Admiralty Inlet was not the first one given. The Wilkes Expedition (Volume IV., page 479) makes use of the name Admiralty Sound, but in present usage the name Puget Sound is encroaching on the other.
On the original chart of Vancouver, Admiralty Inlet extended to where the city of Tacoma is now located. On the United States Coast and Geodetic Survey Chart, 6450, dated February, 1905, Admiralty Inlet ends and Puget Sound begins at the lower end of Whidbey Island. [Edmond S. Meany.
