The Significance of Zebulon Pike’s journey is discussed below.
Explanation:
Zebulon Pike, the United States Army officer who in 1805 commenced an expedition company in quest of the reservoir of the Mississippi River, begins with a unique campaign to investigate the American Southwest.
Pike was commanded to attempt out headwaters of the Arkansas and Red streams and to examine Spanish establishments in New Mexico.
Roughly contemporaneous with the Lewis and Clark Expedition, it was led by United States Army Lieutenant Zebulon Pike, Jr. (He was promoted to captain while on the trip.) It was the first official American effort to explore the western Great Plains and the Rocky Mountains in present-day Colorado.
