How many members were in the Corps of Discovery?

• A. 20
• B. 40
• C. 30
• D. 50

Answer: (C)

The group size and makeup of the Corps of Discovery show why a relatively small, carefully chosen team was used for this journey. Lewis and Clark led a compact expedition that needed enough people to perform essential tasks—navigation, hunting, carrying supplies, and interpreting with Indigenous peoples—without becoming unwieldy or overburdened by heavy supplies. About thirty people is the number most often cited for the core crew who traveled the full length of the voyage, though the roster did change along the way as some members joined or left. This size reflects the balance between mobility and capability: large enough to accomplish the mission with diverse skills, but small enough to move efficiently through unfamiliar terrain and maintain manageable logistics.
