Review Questions

  • How did the Lewis and Clark Expedition contribute to our understanding of the geography and resources of the Pacific Northwest?
    • The Lewis and Clark Expedition significantly enhanced knowledge about the geography and natural resources of the Pacific Northwest. By mapping rivers like the Columbia and documenting various terrains such as the Cascade Range, they provided crucial information for future settlers. Their detailed observations about local flora and fauna also laid the groundwork for future scientific research and exploration in the region.
  • In what ways did the outcomes of the Lewis and Clark Expedition influence early American settlers traveling along the Oregon Trail?
    • The Lewis and Clark Expedition provided vital information that directly influenced early American settlers on the Oregon Trail. The maps created by Lewis and Clark showcased routes, water sources, and potential settlements along their path. Their journals offered insights into interactions with Native American tribes and tips on surviving in new territories, which were essential for settlers as they moved westward seeking land and opportunity.
  • Evaluate the long-term impacts of the Lewis and Clark Expedition on American expansionism into the Oregon Territory and its relationship with Native American tribes.
    • The Lewis and Clark Expedition set a precedent for American expansionism into the Oregon Territory by establishing a claim over vast lands previously inhabited by Native American tribes. While it opened up opportunities for settlement and resource exploitation, it also initiated a complex relationship marked by both cooperation and conflict with Indigenous peoples. As settlers moved westward following this expedition, they disrupted traditional ways of life for many tribes, leading to significant cultural changes and tensions that would shape U.S. history in subsequent decades.
