YELLOWSTONE NATIONAL PARK - Madison Junction to West Thumb
With half of the earth’s geothermal features, Yellowstone holds the planet’s most diverse and intact collection of geysers, hot springs, mudpots, and fumaroles. Its more than 300 geysers make up two thirds of all those found on earth.

0.5	0.3	Point of Information	Crossing the Gibbon River. The Gibbon River flows from Wolf Lake through the Norris area and meets the Firehole River at Madison Junction to form the Madison River. Both cold and hot springs are responsible for the majority of the Gibbon's flow. Brook trout, brown trout, grayling, and rainbow trout find the Gibbon to their liking. The Gibbon River is fly-fishing only below Gibbon Falls.
0.8	0.5	Access to Fire Hole Canyon Drive	West side of highway. Firehole Canyon Drive, a side road, follows the Firehole River upstream from Madison Junction to just above Firehole Falls. The drive takes sightseers past 800-foot thick lava flows. Firehole Falls is a 40-foot waterfall. An unstaffed swimming area here is very popular in the warmest of the summer season. Cliff diving is illegal.

12.8	8.0	Access to Lower Geyser Basin - Painted Pots Thermal Area	Walkway Area West side of highway. This large area of hydrothermal activity can be viewed by foot along the boardwalk trail at Fountain Paint Pots and by car along the three mile Firehole Lake Drive. The latter is a one-way drive where you will find the sixth geyser predicted by the Old Faithful staff: Great Fountain. Its splashy eruptions send jets of diamond droplets bursting 100-200 feet in the air, while waves of water cascade down the raised terraces.

13.7	8.5	Access to Firehole Lake Drive	East side of highway. Firehole Lake Drive. Great Fountain Geyser - Eruptions average 100 ft, but some visitors are luck enough to see it erupt with rare 200 ft eruptions. Eruptions typically occur every 8-10 hours. During this time the crater fills, and begins to overflow. If the water begins to boil violently, an eruption could occur. For the most part Great Fountain Geyser is dependable.

Also in this surprising basin is Yellowstone's largest hot springs, Grand Prismatic Spring. This feature is 370 feet in diameter and more than 121 feet in depth.

23.8	14.8	Access to Old Faithfull Geyser Thermal Area	Old Faithful erupts more frequently than any of the other big geysers, although it is not the largest or most regular geyser in the park. Its average interval between eruptions is about 91 minutes, varying from 65 - 92 minutes. An eruption lasts 1 1/2 to 5 minutes, expels 3,700 - 8,400 gallons (14,000 - 32,000 liters) of boiling water, and reaches heights of 106 - 184 feet (30 - 55m). It was named for its consistent performance by members of the Washburn Expedition in 1870. Although its average interval has lengthened through the years (due to earthquakes and vandalism), Old Faithful is still as spectacular and predictable as it was a century ago. Old Faithfull Web Cam
