Clark was afterwards Governor of the territory, when its name had been changed to Missouri, and he also served honorably as Indian agent.

But neither of them did anything further of note; nor indeed was it necessary, for they had performed a feat which will always give them a place on the honor roll of American worthies.
Pike and his Explorations.
While Lewis and Clark were descending the Columbia and recrossing the continent from the Pacific coast, another army officer was conducting explorations which were only less important than theirs.

This was Lieut.
Zebulon Montgomery Pike.

He was not by birth a Westerner, being from New Jersey, the son of an officer of the Revolutionary army; but his name will always be indelibly associated with the West.

His two voyages of exploration, one to the head-waters of the Mississippi, the other to the springs of the Arkansas and the Rio Grande, were ordered by Wilkinson, without authority from Congress.
