The hunters did know it was a bow kill as the other hunter who helped me pack the elk ran into them and they told him so. It wasn't really a big deal to me, I just found it kind of surprising when I opened her mouth.
Biggamefish, no I don't sell the ivories but I did have a real cool ring made for my wife with my first set of ivories. Its just something a lot of elk hunters collect from their kills. They are not teeth but actual ivory like a tusk. I have heard that they are the remains of an ancient time when elk used to have tusks in the mastadon era but have no idea if that's true?
