what was the name used on early maps for the area west of the mississippi river?


"Unexplored Territory" on most of it before Lewis & Clark in 1803. They headed the exploration and were demographers.

The Colorado River was uncharted and went into unknown territory until 1869:

A complete map of the Grand Canyon didn’t exist until 1927:
