- While the principal focus is the history of river-running, the collection also touches, often in depth and with original materials, on the geology of the entire region, the history of mining, water issues, hydroelectric power development, recreational use and policy issues, the history of transportation, the ecology of various riverine ecosystems, exploration, the film industry and promotion of the West, and indigenous cultures.
