:''For the Portuguese island, see São Miguel Island.'' San Miguel Island is the westernmost of California's Channel Islands, located across the Santa Barbara Channel in the Pacific Ocean, within Santa Barbara County, California. San Miguel is the sixth-largest of the eight Channel Islands at 9,325 acres (37.74 km2 or 14.57 sq mi), including offshore islands and rocks. Prince Island, off the northeastern coast, measures in area. The island, at its farthest extent, is long and wide. San Miguel Island is part of Channel Islands National Park, and almost all of the island () has also been designated as an archaeological district on the National Register of Historic Places. This westernmost Channel Island receives northwesterly winds and severe weather from the open ocean. The cold and nutrient-rich water surrounding the island is home to a diverse array of sea life that is not found on the southern islands. San Miguel Island, together with numerous small islets around it, is defined by the United States Census Bureau as Block 3010, Block Group 3, Census Tract 29.10 of Santa Barbara County, California. The island is uninhabited.〔(Block 3010, Block Group 3, Census Tract 29.10, Santa Barbara County ) United States Census Bureau〕 Highest peak is San Miguel Hill, at . Submerged rocks make the nearly coastline a mariner's nightmare. == History == Archaeological research has shown that San Miguel Island was first settled by humans at least 12,000 years ago, in the Millingstone Horizon archaeological period. Because the northern Channel Islands have not been connected to the adjacent mainland in recent geological history, the Paleo-Indians who first settled the island clearly had boats and other maritime technologies. Rough seas and risky landings did not daunt the Chumash people. They called the island ''Tuquan'' in the Chumash language, and for several centuries, they used plank-built canoes, called tomols, to reach their settlements. The first European explorer to land was the Portuguese explorer, João Rodrigues Cabrillo in 1542, who died on the island and is buried there. Ranchers raised sheep here from 1850 to 1948. One of the ranch families that homesteaded the longest was the Lesters, a family of four that left the island at the time of Pearl Harbor due to the dangers posed by the war. Later, the United States Navy used the island for a bombing range. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「San Miguel Island」の詳細全文を読む スポンサード リンク
