This is one of the maps resulting from the Navy Exploring Expedition of 1838-1842 commanded by Commodore Charles Wilkes (1798-1877). The Great Basin is still poorly known and details of the Southwest are sparse. The rivers of southern Arizona are not any more accurately delineated, and the names are mostly incorrect. The Santa Cruz River is labeled "R. S. Pedro", and the San Simon River is "R. Suanaca". The San Francisco River is correctly labeled "R. S. Francisco". The village of Tumacacori (as "Termacacori") is mislocated far to the west, as also are the villages of Santa Cruz and Buena Vista. Note that Tucson is now spelled "Toyson".
