John Evans (explorer)

John Thomas Evans (April 1770 – May 1799) was a Welsh explorer who produced an early map of the Missouri River.

Iolo Morganwg had originally intended to explore the Missouri to discover these Welsh Indians, and Evans was to have gone with him.

However, Iolo withdrew from the expedition and Evans embarked for the United States alone, arriving in Baltimore in October 1792.

In April 1795 he set off on an expedition with Spanish backing to explore the Missouri and to try to discover a route to the Pacific Ocean from its headwaters.

In 2014, the history of John Evans gained renewed popular interest as the topic of a book, film, album and mobile application, all entitled American Interior, created and produced by Welsh musician Gruff Rhys, vocalist with Super Furry Animals.
