"Potomac" is a European spelling of Patawomeck, the Algonquian name of a Native American village on its southern bank.[10] Native Americans had different names for different parts of the river, calling the river above Great Falls Cohongarooton, meaning "honking geese"[11][12] and "Patawomke" below the Falls, meaning "river of swans".[13] In 1608, Captain John Smith explored the river now known as the Potomac and made drawings of his observations which were later compiled into a map and published in London in 1612. This detail from that map shows his rendition of the river that the local tribes had told him was called the "Patawomeck". The spelling of the name has taken many forms over the years from "Patawomeck" (as on Captain John Smith's map) to "Patomake", "Patowmack", and numerous other variations in the 18th century and now "Potomac".[12] The river's name was officially decided upon as "Potomac" by the Board on Geographic Names in 1931.[14]
