After
completing my morning regimen, I turned on my computer today and discovered it
is Earth Day. I had been considering the following item as a blog post so this
seems the perfect day to do so.
As
I was listening to NPR several weeks ago on the way to a meeting, a fellow was
being interviewed about a “boiling river” he had discovered (not as in being
the first to see it, but as a new geographical feature to him—and many others).
I
wasn’t taking notes as I listened, naturally, so later I did a search on the
internet in hopes of finding further information on this “boiling river.”
Bingo! It popped right up on my computer screen.
A
young Peruvian geoscientist, Andres Ruzo, had been fascinated about the myth of
a boiling river since he was a child. But it wasn’t until he began writing his
PhD thesis on geothermal potential in Peru that he began to wonder if such a
thing was possible. All the experts told him that hot rivers exist but they are
somehow connected with volcanoes. There are no volcanoes in the area Ruzo
hailed from.
In
2011 Ruzo hiked into the Amazon forest with his aunt. She and his mother claimed
they had actually swam in a portion of the boiling river as youngsters (obviously
not the hottest part). When Ruzo arrived, he saw a river rising with steam, so
he whipped out his thermometer and took its temperatureJ It was 86 degrees Celsius—not
quite boiling but definitely hot enough to cook.
Thermal
pools in other parts of the world get to this temperature, but he witnessed a
huge area at that heat—25 meters wide, 6 meters deep, extending for 6.24 km.
(When you translate that to US measurements that is roughly 75 feet wide, 18 feet
deep, extending maybe 3-4 miles) I’m not sure of my conversion figures but that
is a lot of hot water.
The
river is 700 km from the closest volcanic system so Ruzo wanted to discover the
mysterious source of this boiling river. He got permission from the local
Shaman
to study the river and its ecosystem. He discovered the hot water comes from
fault-fed hot springs. Here’s the example given: “Imagine Earth like a human
body, with fault lines and cracks running through it like arteries. These
‘Earth arteries’ are filled with hot water, and when they come to the surface,
we see geothermal manifestations, like the boiling river.”
The
river water was analyzed and was shown to have originally fallen to earth as rain. Ruzo
hypothesized this happened far upstream and the rain water seeped down into the
ground where it was heated up by Earth’s geothermal energy and then emerged as
the boiling river.
The
next statement in this article is totally fascinating. “This [hypothesis] means
the system is part of an enormous hydrothermal system, the likes of which haven’t
been seen anywhere else on the planet.”
Ruzo
has researched the microbes living in the hot water and has discovered new
species. As for swimming in the river, it can be done only after a heavy
rainfall has diluted the hot water--personally, I wouldn’t want to chance it. Normally, the indigenous people use the hot water for brewing tea and cooking.
(I wonder if some enterprising person has discovered how to pipe it into their
home?)
That’s
the science lesson for Earth Day 2016. Once again we see how wondrously our
Creator has formed our world and everything in it.
