Why did so few people settle west of the Mississippi river between 1700 and 1800?

Between 1700 and 1800, few people settled west of the Mississippi River mainly due to the challenges posed by the region's geography and climate, which included dense forests, mountains, and a lack of established infrastructure. Additionally, the threat of conflict with Native American tribes, who inhabited these lands, deterred many settlers. Furthermore, the British and later American governments focused on consolidating control over the eastern territories before encouraging westward expansion. Lastly, the lack of economic opportunities and resources in the West during this period made it less attractive for settlement.
