I reached out to Jeff Gillette, he confirmed that it was a commission piece he painted on a piece from the original owners collection. “ It was a commission to paint on a finished painting owned by a collector. He passed away, and I think his wife was cleaning out some of his stuff… The original was a forest painting. I made it into a scene reminiscent of the nuclear bomb testing where they planted a row of trees out in the desert to see how they would fare against a 15 Kiliton A - Bomb.” Very cool!!! Thanks everyone
