The Deception Pass area has been home to various Coast Salish tribes for thousands of years. The first Europeans to see Deception Pass were members of the 1790 expedition of Manuel Quimper on the Princesa Real. The Spanish gave it the name Boca de Flon.[1] A group of sailors led by Joseph Whidbey, part of the Vancouver Expedition, found and mapped Deception Pass on June 7, 1792.[2] George Vancouver gave it the name "Deception" because it had misled him into thinking Whidbey Island was a peninsula.[3] The "deception" was heightened due to Whidbey's failure to find the strait at first. In May 1792, Vancouver was anchored near the southern end of Whidbey Island. He sent Joseph Whidbey to explore the waters east of Whidbey Island, now known as Saratoga Passage, using small boats. Whidbey reached the northern end of Saratoga Passage and explored eastward into Skagit Bay, which is shallow and difficult to navigate. He returned south to rejoin Vancouver without having found Deception Pass. It appeared that Skagit Bay was a dead-end and that Whidbey Island and Fidalgo Island were a long peninsula attached to the mainland. In June the expedition sailed north along the west coast of Whidbey Island. Vancouver sent Joseph Whidbey to explore inlets leading to the east. The first inlet turned out to be a "very narrow and intricate channel, which...abounded with rocks above and beneath the surface of the water".[4] This channel led to Skagit Bay, thus separating Whidbey Island from the mainland. Vancouver apparently felt he and Joseph Whidbey had been deceived by the tricky strait. Vancouver wrote of Whidbey's efforts: "This determined [the shore they had been exploring] to be an island, which, in consequence of Mr. Whidbey’s circumnavigation, I distinguished by the name of Whidbey’s Island: and this northern pass, leading into [Skagit Bay], Deception Passage".[4]
