Yet another example of the anthropocene discontinuity ...

... to add to the unnaturally "weathered" mountain tops, the large-scale trace fossils
from mineral extraction, the unexpectedly deep layer of bioturbated sediments
and the unnatural deposition of everything from aluminium through iron oxides
up to long-chain polymers.

Future geologists will posit that the planet was hit by a meteorite comprised
mainly of iron, concrete & plastic.
