The Norris Geyser Field is a wide collection of hot pools, fumaroles (steam vents), colorful springs,
and intermittent (shall we call them unfaithful?) geysers.
On the side of the road north of the Norris Fields there is a feature called the Roaring Mountain,
which constantly hisses loudly. And no, the above is not a black-and-white photo. It's like that....
A little further down the same road there is a small lake partially fed by silica-rich springs.
A number of fumaroles can be found in the Norris Field.
... including some sites with several very active vents.
The orange and green colors in the waters of hot springs are produced by microorganisms containing
varying levels of carotene and chlorophyll. To protect both the tourists and the natural structures,
the Park Service has provided and maintained (in this hostile environment) miles of boardwalks.
A small clear silica-lined pool titled The Whale's Mouth.
In some areas the effects of hot spring chemicals are widespread.
A geyser that burbles constantly rather than erupting, with minerals that have turned the
inner rim of the pool dark grey and purple.
A very small silica-lined pool that seems to have little effect on neighboring plants.
The pictures of this trip are divided into several sets:
