My wife and I traveled a bit this weekend and on our way to our destination we sopped at the Rock Stop in Philo, Ca. which has become our favorite place to look around as rock hounds. While there I noticed that they had some carved antlers as well as some carved mammoth tusk and elk antlers as weel as carved stones, jade and gemstones. I did not get pictures of the elk or tusk carvings, but I took a picture of an Eagle from Moose Antler Carving and carved humpback whale/Mermaid and those were just magnificent. I do not know what they used for the whale carving. This is the place where I picked up some California Jade slices for some knife projects.
They have a website:

They are a bit expensive, but everything has to be helicoptered in and out, a weekend trip can cost over $8,000.00, Ouch!
