What was the western boundary of the Louisiana Territory?

The western boundary of the land acquired in the Louisiana Purchase stretches through multiple states. The vast area starts in Montana, Idaho, Wyoming, Colorado and New Mexico.

The Louisiana Purchase took place in 1803 and refers to the land that the United States purchased from France. The vast area acquired included 530 million acres purchased for $15 million.

The acquisition of land resulted in France's failed plans to settle its territory. The French army suffered losses from yellow fever and was on the verge of war with England. This prompted the sale of the land and the end of French occupation of the territory.
