Once in a while it helps to go back in time a little. Indiana is a reasonable place for that, because during the Devonian period, some 390 Million years back, it was covered by a shallow see, a paradise for all kinds of critters small and big. They left us with plenty of fossils, and many of them are easy to find in stream beds.
A famous place with a giant fossil bed is in the Falls of the Ohio State Park. The park itself is quite small and might come as a disappointment, as collecting fossils is obviously not allowed here. But one can take pictures.
This is somewhat serendipitous. I am not an expert, so I am completely clueless what the curious little sculptures on the rock bed are.
Some might be rare, others just pieces of eroded trash. I don’t know.
They are beautiful by themselves, and they set us into perspective: What fossils will we leave for casual visitors in 400 Million years? What will they think they see? Will there be a hint of civilization? What would we like them to see?
Maybe the traces of a hand or a forgotten glove would be enough to tell: There was someone here who built.
