A Message For 12,000 AD
An interesting read about a warning marker system designed to prevent future civilizations or alien cultures from building shopping malls, genetic alteration shops or lobotomy drive throughs on top of our waste dumps:
"These standing stones mark an area used to bury radioactive wastes. The area is ... by ... kilometers (or ... miles or about ... times the height of an average full-grown male person) and the buried waste is ... kilometers down. This place was chosen to put this dangerous material far away from people. The rock and water in this area may not look, feel, or smell unusual but may be poisoned by radioactive wastes. When radioactive matter decays, it gives off invisible energy that can destroy or damage people, animals, and plants.Don't drink the water, children of the future.Do not drill here. Do not dig here. Do not do anything that will change the rocks or water in the area.
Do not destroy this marker. This marking system has been designed to last 10,000 years. If the marker is difficult to read, add new markers in longer-lasting materials in languages that you speak. For more information go to the building further inside. The site was known as the WIPP (Waste Isolation Pilot PLant) site when it was closed in ..."
