Snow Blocks Circles

291 – Snow Blocks Mandala

British sculptor, photographer and environmentalist, Andy Goldsworthy, created this delightful nature sculpture using blocks of snow to forms these amazing circles. I appreciate the “cool-ness” of his art and at the same time I’m in awe of how he managed to create not just one but four of these pieces. How did he do keep them from collapsing in on themselves?
