| Note: | no time - inferred approx date - Hutchinson “Spring Guide to Yellowstone’s Geyser and other thermal features” Revised 3/82 - Recognized as the hottest and most unstable of Yellowstone’s geyser basins, Norris is also one of the most colorful. It is the site of frequent and sometimes violent changes. An old geyser vent near the Norris Museum restrooms re-emerged in February 1981 after almost 35 years of burial. It is now having muddy eruptions several times daily. |
