Norris Geyser Basin
Norris Geyser Basin, considered by many scientists to be the hottest
and most changeable of Yellowstone’s thermal areas, sits at
the intersection of three major faults. There is evidence that hydrothermal
features have existed at Norris for at least 115,000 years. The
features in the basin may change daily, with frequent disturbances
from seismic activity and water fluctuations. Norris is home to
Steamboat Geyser, the tallest active geyser in the world.
Norris Geyser Basin consists of three main areas: Porcelain
Basin, Back Basin, and One
Hundred Spring Plain. The majority of the area’s geysers
and hot springs have temperatures exceeding the boiling point and
many are acidic, with pH values of 2-4.
