This piece of the Nitrogen Plant came from Sally (Asplund) McKay’s farm. It turns out that when the Nitrogen Plant was torn down at least some of the farmers. For the Asplund farm it was used in the cement to help fortify it like rebar or at keep the cements cost down.
Sally says now that the cement is starting to erode, these pieces are starting to show themselves. Inside are spiral rings, but it’s hard to tell since they were filled with cement decades ago.
Who knows, maybe you’ve got a piece of the Nitrogen Plant in your backyard.
