| An article on Stonehenge's giant stones -- and recent reading about Easter Island's great heads -- have caused me to ponder: A million years from now, what traces of humanity will be visible?
- Mountain tops removed for strip mining will remain removed, although erosion may make them less obvious
- Some plastics may remain -- in the oceans and landfills
- Radiation from nuclear waste
- I wonder if any dams will last that long?
- Space junk?
