You're misinterpreting the 50-year rule. Any site or collection of artifacts older than 50 years is eligible to be considered for inclusion in the historical site register when documented because it meets one criterion. The other criteria are things like historical/cultural significance. Please free to clean up all the 20th century trash you find. We have lots of it. Archaeologists don't like documenting pepsi cans either and long-winded arguments on this subject can be found in many journals.
