I replied last night, but don't see it posted here. Dunno what happened. Once it was suggested that this was a mammoth tooth, I knew what to google; sure enough, you folks were right. My wife found the tooth among rocks in a gravel delivery, so I won't be able to dig around for more, unfortunately. I am sure the pit owner and I agree that being run over by a 966 with 5 yards of gravel in his bucket would be a bad idea. A few years ago my son had some bison bones delivered; a 6" fragment and some horn tips that the museum identified for me. I am in Fairbanks, AK.
