Blood on the tracks

If delicate creatures have left fossils which have survived millions, even billions of years, then I'm sure human artifacts will be left behind too. For example, in Florida, a landscape primarily made up of alternating layers of sand and limestone, fist-sized granite rocks have been imported to provide a stable bed for railroad tracks. Long after the rails, ties, and spikes dissolve to dust, future geologists may be digging up long ribbons of scattered igneous rock fragments marking these ancient transport arteries. The life blood of a lost civilization. The question is, will those future diggers be human?

Only tectonic subduction, the deposition of deep sediment layers, or submergence under the deep ocean basins will wipe out all evidence of us.
