Despite this evidence, however, the depiction of California as an island revived in the early 17th century. One contributing factor may have been the second voyage of Juan de Fuca in 1592. De Fuca claimed to have explored the western coast of North America and to have found a large opening that possibly connected to the Atlantic Ocean — the legendary Northwest Passage. De Fuca's claim remains controversial because there is only one surviving written account of it found, his account as related to an Englishman, Michael Locke. Nonetheless, this account claims de Fuca found a large strait, with a large island at its mouth, at around 47° north latitude. The Strait of Juan de Fuca is in fact at around 48° N, as is the southern tip of the large island now called Vancouver Island, while the northern reach of the Gulf of California terminates much farther south, at about 31° N. It is possible that explorers and mapmakers in the 17th century could have confused the two (if, in fact, they were aware of de Fuca's voyage), and in any case further exploration was inevitable. Indeed, the famed British explorer James Cook narrowly missed the Strait of Juan de Fuca in March 1778, almost 200 years later. Cook even named Cape Flattery (at the northwest tip of modern Washington state) which is at the mouth of the strait, and stopped in Nootka Sound just off the west coast of Vancouver Island at about 49° N. His account states "we saw nothing like [the Strait of Juan de Fuca]; nor is there the least probability that ever any such thing existed." However, Cook describes some bad weather in his account around this time, and did continue on to map most of the outer Pacific coastline of North America from modern-day northern California to the Bering Strait in Alaska on the same voyage. A key role in changing ideas about California seems to have been played by an overland expedition led by the founding governor of Santa Fe de Nuevo México, Juan de Oñate. The expedition descended the Colorado River in 1604 and 1605, and its participants believed that they saw the Gulf of California continuing off to the northwest (presumably behind the Sierra de Los Cucapah into the Laguna Salada Basin and Lake Cahuilla). Reports from Oñate's expedition reached Antonio de la Ascención, a Carmelite friar who had participated in Sebastián Vizcaíno's explorations of the west coast of California in 1602 and 1603.
