Missouri and Spanish maps

The U.S Expedition was based on these maps. More than 2/3 of the route was done with the help of maps made by the Spanish
The Spanish explored the area
The information that was collected and the data were reflected in maps that were of great help to the later Lewis and Clark expedition based on the previous Spanish expeditions.
