WHITE ROCK

city, southwestern British Columbia, Canada. It lies just southeast of Vancouver on the northern shore of Semiahmoo Bay, at the entrance to the Strait of Georgia. The city is named for a large white rock that, according to an Indian legend, was thrown across the water from Vancouver Island (to the west) by a sea god's son. The rock was used as a navigational aid by early mariners. White Rock is a Pacific port of entry directly northwest of Blaine, Wash., and part of the Vancouver metropolitan area. The site, laid out in 1905, soon became a vacation area. Peace Arch (1921) and International Park mark the western extremity of the U.S.-Canadian border. The city has a large retired-worker community. Pop. (1991) 16,314.
