A few times when on hikes I’ve come across a weird orange patch in a creek. This is different than just a section of water that’s turned orange from red clay run-off – this is a distinctive orange section of an otherwise clear stream: Notice that the water on the left is clear and running smoothly over the rocks while the slower-moving water on the right is orange. Is it pollution? Is it dangerous? Should I not let my dog near it? These pictures are from the creek that runs through our yard, so that question became even more urgent. Based on the distinctive coloring, I even began to wonder…
Here's a cool article I just saw today that says scientists have found that tsunamis have a magnetic field that arrives on shore even before the water begins to recede. The idea is that we might be able to use that for an early warning system. Now I'm wondering if it's possible that's how animals know a tsunami is incoming? There are so many stories of animals acting oddly before a tsunami arrives. Could the magnetite deposits in their brains (and ours?) sense this magnetic field?
Wow… What a wonderful rabbit hole! I plan on sharing this with my students as we study water. I look forward to more installations of your thoughts on nature!
Heather ~ Your articles are really interesting. I would not consider myself an "outdoor" girl but I love your facts and "look" into our world around us. I have seen the "rusting" in our lakes....but never gave a thought to why.... Thank you much!
Fascinating, you have brightened my day.
