In other words, the changes we witnessed in the Firehole are also due
to contributions from hydrothermal features! No wonder the river’s
temperature increases—it flows through three major geyser
basins! Just look at our data!
The thermal additions change more than just the river’s temperature.
Water from hot springs and geysers spends hundreds of years working its
way through underground plumbing systems, eroding and carrying along minerals
and elements, such as bicarbonate,
and sodium from the rock
through which it passes. When thermal water empties into the Firehole
River, these minerals and elements are also dumped into the stream. From
the Upper Geyser Basin alone, the Firehole receives an estimated 68 tons
of bicarbonate and chloride every single day! Your data shows
that the pH level of the water rises as the stream passes through the
geyser basins—this is largely due to the added bicarbonate.
the Firehole River become more or less acidic?
chemical that is a variety of carbonic acid salt; some bicarbonates
are used as antacids
compound containing chlorine
salt of arsenic acid
light, silver-white metallic element; when sodium is combined with
chloride, the compound is known as salt
