Triangle Island

 island, nature conservation park / area

Triangle Island (85 ha) is the outermost of the Scott Islands group about 45 km northwest of the north end of Vancouver Island. Tiny, treeless and uninhabited, the Anne Vallée Ecological reserve is the largest and most diverse seabird colony in B.C., established in 1971 to protect the nesting place for one-fifth of BC's breeding seabirds, more than any other island on the coast. It has the largest colony of Cassin's Auklets in the world (360,000 pairs, 40% of the world population) and the largest colony of tufted puffins on the coast south of Alaska (25,000 pairs).
Additionally, hundreds of subadult male California Sealions spend the spring on Triangle's beaches, but disappear by mid-summer. The Steller's sea lion rookery at Triangle Island is the largest in Canada, and in the aftermath of alarming population declines in parts of Alaska in recent decades, is now the second largest in the world.

In 1910 a lighthouse was established on the island, however it was soon discovered that the light was of not much use. The Triangle Island Lighthouse was decomissioned in 1918 and dismantled in 1920. The lens and the dome of this lighthouse has been preserved at the Sooke Regional Museum in Sooke, B.C.
