Hot Springs At Yellowstone Changed Their Color Due To Tourist Activity

An anonymous reader writes Researchers say that the different colors of the hot springs in Yellowstone National Park are caused by human contamination. From the article: "Researchers at Montana State University and Brandenburg University of Applied Sciences in Germany have created a simple mathematical model based on optical measurements that explains the stunning colors of Yellowstone National Park's hot springs and can visually recreate how they appeared years ago, before decades of tourists contaminated the pools with make-a-wish coins and other detritus. If Yellowstone National Park is a geothermal wonderland, Grand Prismatic Spring and its neighbors are the ebullient envoys, steaming in front of the camera and gracing the Internet with their ethereal beauty. While the basic physical phenomena that render these colorful delights have long been scientifically understood—they arise because of a complicated interplay of underwater vents and lawns of bacteria—no mathematical model existed that showed empirically how the physical and chemical variables of a pool relate to their optical factors and coalesce in the unique, stunning fashion that they do."

      News flash, the pools change color overtime time anyway. Birds drown in them because they think they are normal lakes, dirty sediment water runs off in to it and other animals fall in.

      And people dump all kinds of crap in those pools too. The problem isn't that humanity is evil, though obviously that is a seductive narrative for the occasion, but simply that there's so many people visiting.

      If you were to drop a bison in, it would quickly, over the course of a few days be rendered down (in the original sense of the word) to at most a few tens of kilograms of bone. Further, they aren't the smartest animals in the Park, but they're smart enough to avoid Grand Prismatic. So on the animal side you're left with things like hapless ducks who didn't get the memo.

      On the plant side, you basically have wind-blown leaves (wood is durable, but it doesn't grow in hot springs for some reason) which don't last either. The spring happens to be set back from the hillside behind it so you're not getting a lot of silt. There's not a lot of natural mass going into Grand Prismatic.

      On the other hand, if a hundred thousand tourists per year (of the many more visitors who actually walk by the hot spring) each toss a penny into the spring (which isn't hard to do since the boardwalk goes up to the edge of the spring), then you're adding 200 kg of copper and zinc to that spring every year. And those coins tend to stick around even in weakly acidic waters of Grand Prismatic. I think the National Park Service has been successful at keeping people from dumping a lot of junk in the spring, but it is a never ending battle. Evil humanity has been kept at bay, yay. But if they stopped doing it, human litter would probably plug up the spring (third largest in the world) in a few decades.

      A much smaller spring is far more susceptible to this sort of problem. The popular Morning Glory Pool has changed its colors over the years due to human litter (coins, beer cans, etc). And they're pretty sure it's human because they dredge up the debris in the pool every so often to keep it active (and there apparently is a noticeable difference before and after).

      Over the 30 years I've been visiting Yellowstone, I've never seen a beer can in Morning Glory. However, Old Faithful has become less faithful due to shifting underground in those same 30 years. Why is it that Old Faithful geyser plumbing can change on it's own due to natural forces, (and I'm pretty sure no human has walked up to it and chucked a penny into the blow hole) yet Morning Glory is totally the fault of humans?

      I'll call bullshit. If you want to say the temperature of the pool has changed, so be it. If it's clogged by a cinder block, or a 1950's Buick rusting away, then remove it. But stop blaming human activity for everything -- because when you do, all that will happen is they'll remove the boardwalk so my Son can't walk up and see it.
