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.
