Barrier to fish migration

When the Washburn and Hayden parties traveled through the Firehole River and Gibbon River basins in the 1870s, the Gibbon River above Gibbon Falls was barren of fish, the falls being a natural barrier to upstream migration. Unlike the Yellowstone drainage, the upper Gibbon was isolated from any connection to drainages on the Pacific slope. The absence of fish was overcome in 1890 when the first Rainbow trout
