Explanation: 

Detailed explanation-1: -The expedition aided the expansion of the fur trade. The expedition also strengthened U.S. claims to the Pacific. Another of the expedition’s objectives-diplomacy with Native Americans-was accomplished. The expedition held numerous councils with American Indians and promised trade with them.

Detailed explanation-2: -The most noticeable immediate effect was the rise in the northern plains fur trade between 1806 and 1812. During that period individuals like Manuel Lisa and John Colter–the latter a member of the Corps of Discovery–established short-lived trade from northern South Dakota to Montana.

Detailed explanation-3: -After reaching the Pacific Ocean in November 1805, the corps established Fort Clatsop, near present-day Astoria, Oregon, as its winter quarters. Then, on March 23, 1806, the weary explorers headed for home and St. Louis. They retrieved their horses from the Nez Percé Indians and crossed the Bitterroot Mountains.

Detailed explanation-4: -Nevertheless, the expedition contributed significant geographic and scientific knowledge of the West, aided the expansion of the fur trade, and strengthened U.S. claims to the Pacific. Clark’s maps portraying the geography of the West, printed in 1810 and 1814, were the best available until the 1840s.
