Gibbon River Drainage Professional Review and Guide
"The Gibbon River rises on the south flank of the Washburn Range, flowing out of Grebe Lake. The Hayden survey of 1872 named the river for General John Gibbon, who was then touring in the park. After flowing west to Wolf Lake, the river splashes over Virginia Cascade and oozes into Norris Geyser Basin. Hooking around Norris Geyser Basin proper, the river takes a southerly course through Elk Park, Gibbon Meadows, and the Gibbon Canyon before plummeting 88 feet over Gibbon Falls.
Its final act bends back to a westerly course to join with the Firehole River, forming the Madison River, at Madison Junction. The stream passes near Ice Lake, which was stocked repeatedly up until about 1960. The lake is subject to freeze-out and has no substantial inlet. The outlet is not large enough to permit either consistent spawning or migration. The last surveys turned up no fish. This eTrail contains information on Grebe Lake, Upper Gibbon River (Grebe Lake to Norris Meadow), and Lower Gibbon River (Norris Geyser Basin to Madison Junction)."
