A- Pike helped establish the Wilderness road

Zebulon Pike's findings encouraged settlers to move to the Southwest.

Explanation:

The Pike Expedition was a reconnaissance campaign led by US Army captain Zebulon Pike (1778-1813) to explore the south and west of the newly acquired territories of the Louisiana Purchase. Approximately contemporary to the Lewis and Clark Expedition, the Pike Expedition was the first effort to explore the western Great Plains and Rocky Mountains in the current state of Colorado. This expedition allowed to map the territories of the North American Southwest, thus promoting the settlement of the area by American people.
