Mastadon tusk and tooth?

I had a local tell me about a 4 foot long tusk that is really old that she and her family found at a lake 45 minutes from here. It sounds like they found it some summer past. They also found a tooth about as big as a shoe box in this lake. In talking, it sounds like a mastadon tusk and tooth. She has it at her house. I told her that I want to get a picture of it before I go back to Portland. I hope to get a picture of them up but may not because I don't want to invade her privacy. I might just send it to those interested in an email. (Also, my device to download pictures broke! I need a new one.)
