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.

Excellent public information site with displays showing the Weldon Spring contribution to the Manhattan Project. Good 1-2 hour visit with teenage kids. Friendly and helpful staff. Quite interesting.

If you're into this sort of thing, and you have an hour or two to spare to read through the wealth of information here, this might be an interesting spot. There are a lot of slick, detailed displays in the museum/welcome center that would provide a very extensive explanation of the site to anyone who had the time and the... More

Weldon Spring has an interesting history. It was once the world's largest explosives manufacturing factory. By the time World War II ended, the factory had produced more than 700 million pounds of TNT. About a decade later, Weldon Spring became the site of a uranium ore processing plant--making yellow cake uranium. Almost a decade after that, the government made plans... More

The history of the site: 20,000 people displaced in order to make room for TNT and then Uranium production site in support of WWII. Eventually the whole place was vacated and EPA had to step in. This site, in my opinion, does an very good job of capturing the whole story - from start to finish.

We drove past this place many times on our way to wineries along the Missouri River. It’s in a state park, attractive countryside with bike and hiking trails, lake and ponds, grasslands and woods. We thought we should take time to see what the area offered and stop at the Interpretive Centre and find out about the spring. On one... More

This place has a wonderful interpretive center. It explains all about how the area was contaminated when uranium was processed here and then was cleaned up. The kids also learn about geology and soil! My kids even thought it was cool!
