Active earthquake area leading to thermal imbalance; Combination of rare acidic and alkaline geysers; One of Yellowstone’s hottest geothermal areas; Ever-changing geysers and hot springs; Intersection of three major faults – That’s Norris Geyser Basin in a nutshell. Start your hike from the Porcelain Basin Overlook just a little past the museum; the overlook provides an excellent view of the Basin, full of life with geysers, hot springs, fumaroles and mud pots. To me, the blue pools were the most attractive of all. You’ll see how nature had played around with the different colors, formed by different chemicals and micro-organisms that thrive in the heat. After completing the Porcelain Basin loop, walk through the Back Basin to see other geothermal features. The lovely green Emerald Spring is not to be missed. Steamboat Geyser, whose last major eruption was in 2014, still sends out minor eruptions. Echinus Geyser, which once erupted regularly is also a popular feature in the basin. Porkchop Geyser, although not very clearly seen from the boardwalk emanates a brilliant blue color. We were fortunate to see the tall and narrow eruption of Vixen Geyser.
