The United States parliament facilitated exploration of the American West throughout the 19th century, as the United States developed from sea to sea shining. However, the westward expansion transformed the landscape from the forest into the farming garden and fields with the help of white American settlers.
The westward development prompted Americans to disobey the territorial rights of native Americans, demolishing many tribes and inflicting attention, cultural divide, and conflict.

Moreover, the Appalachians that ran from southeastern Canada to central Alabama was the physical barrier that prevents westward territories. Which was later destroyed by the government-sponsored Daniel Boone as he navigates the road to the fertile land beyond the mountain.
