Messages in the Rocks #2

Rocks are like little history books – sometimes what they’re made of can tell us a lot, and sometimes they record other kinds of history for us!

Here’s a photo of a rock on one of our trails. It’s saying something – can you figure out what it’s telling us? I’ll give you a hint – it’s not what it seems, and you can find a whole lot of it at the Cove!

Need another hint? What we’re looking at…. is alive!

lichen

Even though this image is a little blurry, you can see that it’s bumpy! That cool reddish-orange stuff that this silly ranger thought was the pigment used in an undiscovered rock painting is actually lichen. Although I’m a little bummed that I didn’t discover an ancient message from the original inhabitants of the area, lichen is pretty cool stuff – did you know that it’s comprised of two organisms working together? It’s true: lichen is made of fungi and algae, and the dark red color protects the algae from too much UV radiation in hot, dry climates. So the message this rock has for us is that no matter how harsh the climate, living things can thrive! (And fool us, even when we’re used to looking at them every day…)
