George Vancouver: Proving the Island, Drawing the Salish Sea

Between 1791 and 1795 George Vancouver led one of the most exacting hydrographic surveys of the age. In 1792–1794 his crews in HMS Discovery and the tender Chatham traced the maze of channels from Juan de Fuca Strait through today’s Salish Sea, worked cordially alongside Spanish surveyors, and produced charts that finally fixed Vancouver Island on the map as an island.

Orders, ships, and the plan

After Cook’s voyages suggested no easy Northwest Passage from the Pacific, the Admiralty sent Vancouver to “examine with the utmost accuracy” every inlet from California to Alaska. He sailed in HMS Discovery with the brig Chatham as tender, using small boats for laborious inshore work while the ships stood off in safer water.

Into Juan de Fuca and Puget Sound, spring 1792

Vancouver entered the Strait of Juan de Fuca on April 29, 1792, then spent May and early June charting the deep south‑branch he named Puget’s Sound after his officer Peter Puget. He marked volcanic sentinels too: Mount Baker (named for Joseph Baker, April 30, 1792) and Mount Rainier.

Meeting the Spanish and a rare joint survey

In June 1792, near today’s Birch Bay and Point Roberts, Vancouver’s boats encountered Spanish schooners Sutil and Mexicana under Dionisio Alcalá Galiano and Cayetano Valdés. For several weeks the two expeditions compared charts and divided the work of sounding and tracing the newly revealed inland sea before parting amicably to continue their surveys.

Through the Salish Sea: Burrard Inlet, Howe Sound, Desolation

Working north from the strait, Vancouver’s parties threaded Howe Sound, Jervis Inlet, and the deep fjords that make the coast so intricate. On June 13, 1792 he named Burrard Inlet after a former shipmate, even as Musqueam, Squamish and Tsleil‑Waututh villages lined those shores. His journals recorded Indigenous presence and names, yet his charts replaced many with British naval honorifics that still dominate the map.

Nootka negotiations and a name with two captains

Vancouver reached Nootka Sound in August–September 1792 to implement the Nootka Convention with the Spanish commandant, Juan Francisco de la Bodega y Quadra. The two could not resolve the legal tangle, but their cordial meetings inspired a diplomatic gesture: early maps labeled the great island “Quadra and Vancouver’s Island,” later shortened to Vancouver Island.

Proving it’s an island

By late summer 1792, the combined British–Spanish work made the picture clear: the landmass west of the Strait of Georgia and north of Juan de Fuca was insular. Spanish boats completed the first full circumnavigation that year, while Vancouver’s larger expedition verified key channels and, in charts published in 1798, cemented the finding for British audiences.

Hard miles on a hard coast

The survey demanded patience and seamanship. Both Discovery and Chatham touched rocks in the inlets; crews rowed for weeks up blind waterways only to find another dead‑end. Yet by 1794 Vancouver had charted from California to Alaska with a precision that stood for decades.

Legacies on the map

Vancouver’s toponyms—Burrard Inlet, Port Discovery, Hood Canal, Puget’s Sound—and his coastal profiles shaped how Europeans wrote and navigated the region. They also sit atop much older Indigenous geographies and names that communities continue to preserve and restore.

Disease, depopulation, and possession: smallpox and the mapmaking mindset

During the 1792 survey season, Vancouver’s party repeatedly noted signs of earlier smallpox epidemics in Puget Sound and the inland sea—pock‑marking, blindness, and reduced populations at villages they encountered. These observations fit what historians now recognize as the westward tail of the massive 1779–1783 pandemic that reached the Northwest Coast before sustained European settlement.

Vancouver also staged formal “acts of possession.” On the King’s birthday (reckoned by his ship’s date) he came ashore near today’s Everett and claimed the surrounding waters and lands for Britain, naming Possession Sound and Possession Point. Similar ceremonies and exhaustive naming were part of an imperial playbook: plant a flag, write a claim into the log, and fix new names on charts.

Historians stress that British imperial law in North America was not a simple blank‑slate doctrine; the Royal Proclamation of 1763 recognized Indigenous title. But the on‑the‑ground cartography and ceremony around 1792 often operated as if sparsely settled or “unknown” coasts were available to be claimed. Later nineteenth‑century policy in British Columbia hardened that logic into what scholars call a terra nullius mindset—treating land as if it were available for the taking despite Indigenous presence. Vancouver’s possession rituals and renaming weren’t the origin of that doctrine, but they are early examples of how mapping and ceremony could sidestep Indigenous sovereignties.
