I was very satisfied with my purchase. Although shipping took so long, I forgot I had even ordered them, it was worth the wait. Imagine my surprise when I got home one day and 30 boxes of the Sierra Nevada were sitting on my doorstep. Amateurgeologist.com is the best! Thanks for providing such a unique product. So glad I was able to get some of these authentic limited edition Sierra Nevada cobbles before mass wasting destroyed them all, or before glaciation comes back and covers them all up again.
