Yellowstone Jewels

The close-up images were taken by placing flat slabs of cut rocks on a wet scanner surface and taking a high-resolution scan. The other photos are of various pieces that I cut and polished from rocks found in the Yellowstone or its tributaries in the Beartooth Mountains. There is also a set of natural rocks we have collected (the credit card blank is for size reference), and still another set of rocks that are wet in the rain. I hope you enjoy!
