Manuel Quimper Benítez del Pino, Peruvian Explorer

On May 31, 1790, Peruvian cartographer and naval officer Manuel Quimper Benítez del Pino explored and charted the Strait of Juan de Fuca.  This Strait is the wide waterway stretching from the Pacific Ocean on the west to the San Juan Islands on the east, with Vancouver Island, Canada to the north.  The international boundary between the United States and Canada runs down the center of the Strait.  The Spanish extensively explored and mapped the western coast of the lands that much later became the US and southwestern Canada.
