The "Interpretive Center" has only been open for a decade or so, but the degree of contamination and clean-up has been known since I moved to the area in 1970. Thank goodness that the EPA was formed and the moral compass of the country was...More

Eerie, worth the stop. Hard to believe the history of this place, obviously hidden and kept a secret until it was cleaned up. Now we make it a tourist attraction.

I remember when this really WAS an old abandoned nuclear site. It really was a mess. The fact that the EPA forced a clean-up is impressive, but how they did it even more so. It's worth the visit to the center to read about it....More

Why you would make this an attraction I will never know. No one should be visiting this, especially not children. This a nuclear waste site. Yes, they say it's safe but who really knows. People are dying because of places like this. No way, is...More
