Wormholes in Canyonland

No, this is not about science fiction or physics. The wormholes I observed are for real and they are preserved in stone.

That particular stone actually once was mud at the beach of an ocean or inland lake, where worms left their traces. As the mud got harder, mud cracks developed. All of which was then covered by the next layer preserving those structures for some time (actually quite a bit of time).
