Rainbow colors, hissing steam and pungent odors greet your
senses in Porcelain Basin which is part of the Norris Basin.
Geologic events such as earthquakes cause changes each year
at Norris Geyser Basin. New hot springs
and geysers appear and others become dormant.
Norris is the hottest and most acidic of Yellowstone’s hydrothermal
areas.
Hot springs are superheated water that cools as it reaches
the surface then recirculates.
Fumaroles, steam
vents, are the hottest surface feature emitting only steam.
Mudpots form when acid decomposes surrounding rock to clay,
which combines with water to form mud.
Gases bubble and burst through the mud making plopping sounds.
Mammoth Hot Springs is a travertine hill created over
thousands of years by calcium carbonate being deposited by the hot spring. It is beautiful!
We have enjoyed traveling with Kathy on this wonderful adventure. Unfortunately she is returning to her home at this point. Safe travels and thanks for the memories!
