Description

The Gibbon River rises in the center of the park at Grebe Lake. It flows for a short distance into Wolf Lake. Below Wolf Lake, the river flows through Virginia Cascades into the Norris valley. It flows near the Norris Geyser Basin and through the Gibbon Geyser Basin. From there it flows through the Gibbon River Canyon to its confluence with the Firehole River to form the Madison River. Early maps listed the river as Gibbons Fork or the East Fork of the Madison River. The river between Norris and Madison Junction is paralleled by the Grand Loop Road. The river, along with Gibbon Falls, is named for Colonel John Gibbon,[5] U.S. Army who participated in the 1872 Hayden Geological Survey of Yellowstone.

Angling

The Gibbon River is a popular trout fishing destination. The upper section of river has very difficult access being choked with thick forests and lots of downed timber. The fish, consisting of brook trout, rainbow trout and grayling, are all on the small side, rarely exceeding 10 inches (250 mm). Below Gibbon Falls access is excellent and the river has a healthy mix of rainbow and brown trout. The lower river receives a good run of spawning browns in the fall.[6][7]

The Gibbon River is fly fishing only and catch and release below Gibbon Falls. Above the falls, any grayling or cutthroat trout caught must be released. An unlimited number of brook, rainbow or brown trout may be harvested daily in the waters above the falls.[8]

gollark: How would you know, if it's *secret* police surveillance?
gollark: That seems like a lot for a school project.
gollark: (also, this is probably more <#496135660831375370>)
gollark: (this isn't about a single actual physical molecule or something changing, but the genes for it changing slightly over time and producing different verisons)
gollark: I guess so. If you need, say, ten changes to an enzyme to bring it from one state to a much better one, but it works much worse/totally breaks while it's in the middle of both, it's hard for it to evolve to the better version.
