You can...

read a paper, or a book, but how about a rock,
yessir we've found them, and this isn't any crock;
when people had no paper on which they could write,
they just marked up a rock, and left it in plain sight.

I'd be the first to tell you, I don't know what this means,
could it be a family, showing how they planted beans?
Or, maybe, just maybe, it's some kind of map,
giving directions, to a good place for a nap.

This one show a turkey, and maybe that's a dog,
I read it in a paper, it's a petroglyph, unerroded by fog;
out here in Albuquerque, in the desert sun,
but you can explore the writings, do it just for fun.

This one shows the planets, and the sun and moon,
it could be a calendar, or a lovers swoon;
more than likely, calendar, seems to do the trick,
kind of like building a clock, big one, brick by brick.

There's a man in here, over in the shade,
maybe it's a gravestone, it looks homemade;
or a successful hunter, back from a foray,
you really should see this place, maybe not today.

Enjoy!
