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... read more

A former toxic waste site that was cleaned up. You can learn a little about the contamination, the clean up, and the animals that have reclaimed the area in the information center. The short walk to the top of the concrete shell provides a great view and if you go at the right time, you will be the only one... More

You see a hill, you want to climb it, right? That is what we did. We did not visit the actual interpretive center building as it was early in the day when we went. There is plenty of parking. There were other people there exercising and walking dogs. There was a portapotty available in the parking lot. The walkways are... 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 this ok. Do some research before going and really think about it.

If you like history, this a good place to visit. The waste site is impressively large. You have to walk all the way up though to appreciate it.

The hike up the stairs is pleasant for all ages. The view from the top is so peaceful and beautiful with nice educational stations to read about the history of the site.

Even though they say it is safe, sometimes you got to ask questions. Although compared to how they were disposing of contaminates a few decades ago, I guess we are on the right track. I don't know if I would go out of my way to see this but if near by, it's worth a visit. Interesting, informative and if... More

It's certainly interesting. Walking up to the site that entombs the nuclear waste is an impressive visual. There is a high mound of rocks that you know covers nuclear waste and wildflowers growing all the way around it with cyclists on the trails. You walk up a high set of steps to reach the top where there's information on the... More

This is a hidden gem if you are into history and engineering. A few miles south of I-64 on Route 94 in St. Charles County a huge mound of carefully placed rocks appears to the right of the road. It looks like a dam but why would a dam be at the top of a hill. You turn at a... More

I had never heard of the place. We were driving past and saw the sign and stopped in. Don't get to climb a hill that is covering nuclear waste very often. Neat place we were only there about a half an hour, something different.

Thank Friedheimmo
