Firehole River in Yellowstone National ParkFirehole River in Yellowstone National Park just south of Madison Junction
Joyce took these pictures on our way back to Colter Bay Campground in Grand Teton National Park after visiting the Madison Valley in Yellowstone National Park. The Firehole River flows north for approximately 21 miles from its source in Madison Lake on the Continental Divide. Note that the Firehole River begins and ends in Yellowstone National Park. While it begins on the Continental Divide it ends at Madison Junction in Yellowstone National Park where it joins the Gibbon River to form the Madison River. The Firehole River eventually ends up in the Gulf of Mexico but before reaching the Gulf of Mexico it changes names. The Firehole River merges with the Gibbon River here in Yellowstone National Park to form the Madison River which flows for 180-miles before merging with two other rivers to form the Missouri River at Three Forks Montana, in an area preserved as Missouri Headwaters State Park. The Missouri River flows into the Mississippi River above St Louis, Missouri. The mighty Mississippi River empties into the Gulf of Mexico south of New Orleans, Louisiana.
Firehole River in Yellowstone National Park near Madison Junction
The Firehole River in Yellowstone National Park as it emerges from Firehole Canyon shortly before joining the Madison River at Madison Junction. The geology in Firehole Canyon was extremely hard rhyolite at this point the geology as transitioned to limestone.
Firehole River cutting through hard rhyolite south of Madison Junction
Firehole River flowing through Firehole Canyon a few miles before joining the Gibbon River thus forming the Madison River. The geology of Firehole Canyon is composed mostly of rhyolite lava, which is a pretty stiff type of lava (as opposed to the free-flowing types you're more likely to see on the Big Island of Hawaii. Note the extremely steep walls cut by the Firehole as it flows through this hard rhyolite. Large boulders in the Firehole River between Old Faithful and Madison Junction in Yellowstone National Park
These large boulders are in the Firehole River before it enters Firehole Canyon. In this area the Firehole River parallels Grand Loop Road and presents many wonderful views. We see fly fishermen along this stretch of river later in the summer.
Firehole River flowing through one of the Geyser Basins in Yellowstone National Park
The Firehole River flowing through one of the Geyser Basins near Old Faithful in Yellowstone National Park. While the Firehole River originated at the Continental Divide about 15-miles upstream of this area more volume is being added to the river as it flows through several geyser basins.
In this picture you can see steaming hot water flowing down to join the Firehole River. There is something interesting about that hot water you see entering the Firehole River. The hot water flowing out of those thermal vents has spent several hundreds of years percolating its way through underground channels. As this water percolates it erodes or dissolves the earth and carries with it bicarbonate, arsenate, sodium, and chloride to the surface. Scientist have estimated that the Firehole River carries away 68 tons of chloride and bicarbonate every day. Now that is a lot of dissolved minerals to be carrying away each day.
