which mountain man rediscovered south pass and brought back important information about this trail
Jedediah Smith Jedediah Strong Smith (January 6, 1799 – May 27, 1831), was a clerk, frontiersman, hunter, trapper, author, cartographer, and explorer of the Rocky Mountains, the North American West, and the Southwest during the early 19th century. After 75 years of obscurity following his death, Smith was rediscovered as the American whose explorations led to the use of the 20-mile (32 km)-wide South Pass as the dominant point of crossing the Continental Divide for pioneers on the Oregon Trail.
Northwest Passage The first recorded attempt to discover the Northwest Passage was the east-west voyage of John Cabot in 1497, sent by Henry VII in search of a direct route to the Orient.[16] In 1524, Charles V sent Estêvão Gomes to find a northern Atlantic passage to the Spice Islands. An English expedition was launched in 1576 by Martin Frobisher, who took three trips west to what is now the Canadian Arctic in order to find the passage. Frobisher Bay, which he first charted, is named after him.
