My father, Greg, built this amazing Cairn in the front yard of their home in Northeast Iowa. He found inspiration from a Cairn that was built at the Des Moines Art Center by Andrew Goldsworthy. Each piece was stacked by hand and no mortar has been used to hold the pieces together. It's truly an amazing work of Art. I'm very proud of what my father has created and wanted to share it with the world. It's beautiful, Dad!
