Gallatin River Drainage from Headwaters to Taylor Fork Professional Review and Guide
"The Gallatin River rises high on the north flank of Three Rivers Peak in northwest Yellowstone National Park. Lewis and Clark named this easternmost of the three forks of the Missouri for Albert Gallatin, then Secretary of the Treasury. The Gallatin and the tributaries described here are all mountain freestone streams with fairly steep gradients.
The river flows generally northwest through fairly narrow, timbered canyons and mountain meadows that are more open but still narrow. The most significant tributaries are Fan, Bacon Rind, Specimen, and Sage Creeks.
