NORRIS GEYSER BASIN

This is the Yellowstone area where geothermal demonstrations are hottest and most variable. Throughout the 4 ½ km of trails, we can discover the largest active geyser in the world (Steamboat Geyser, 90 to 120 meters) and the most acidic (Echinus Geyser, pH 3.5), hot springs of all colors and microscopic manifestations in one of the most important environments extremes of the earth. The Norris Museum describes the geological origins of the sources. From there there are two trails to safely observe the areas of Porcelain Basin and Back Basin. Arches, whistle vapors and stinging odors combine to create a unique environment. In Porcelain Basin, in an open setting, we walk amidst a high density of geothermal phenomena (hundreds) while in Back Basin, through wood, these phenomena are more dispersed. Exploration of the One Hundred Springs Plain area is discouraged without guide, because very acidic, rugged and without trails. Artist Paint Pots is a small, but pretty geothermal zone just south of Norris Junction. A walk of a mile in the surrounding area leads to very colorful hot springs, two large volcanoes and part of the forest burned in 1988. Other nearby areas, Sylvan Springs, Gibbon Hill Geyser Basin and Geyser Creek Thermal, are not advised without guidance.
