All documents and books relating to the expedition are of historical value, not only from a travel and discovery perspective but also from a cultural studies standpoint. The ethnocentric descriptions of aboriginal peoples in the places now known as British Columbia, Yukon Territory and Alaska, as well as the general region of Eastern Siberia, typify those attitudes of the time. Telegraph records provide evidence for native land claims such as those of the Gitxsan Nation of northern British Columbia. Dall's records have helped locate Smithsonian exhibits returned to their original native domiciles.
