The shameful, disgusting reason why Yellowstoneâ€™s thermal springs are so beautiful
Joyce Park stashed this in Camping and hiking
It makes me sad to realize that there is some deep-seated part of the human psyche that cannot see something beautiful without wanting to fuck it up.
So basically it's garbage that's changing the color?
Most famously, the Morning Glory Pool used to be bright blue; itâ€™s nowÂ more commonly knownÂ as â€śFading Gloryâ€ť or, even more accurately, â€śGarbage Dump,â€ť because of what happened when humans started clogging it with trash.Â And for the first time, researchers have come up with a model to explain why.
Writing in the journalÂ Applied Optics, researchers at Montana State University and Brandenburg University of Applied Sciences in Germany determined that the unique characteristics of Morning Glory Pool, along with Sapphire Pool and the Grand Prismatic Spring, are related to the springsâ€™ temperatures. Back before Yellowstone became a National Park in 1872, they explain, Morning Glory was significantly hotter, and bluer. But over the years, an â€śaccumulation of coins, trash and rocksâ€ť began to block the underwater vent heating the pool, causing its temperature to drop. That, in turn, created a change in the springâ€™s microbial mat â€” the complex community of microbes dependent on its hot waters â€” ultimatelyÂ shifting the appearance of the shallow waters to the orange, yellow and green spectrum we see now.
