They have a great exhibit at the museum of locally discovered mastedons. I'll believe this exhibit is a permanent exhibit and is always on display. What's fascinating is that you get to see some of the actual bones, such as a skull, up close. I suggest contact them by phone or their website, to see if there are any traveling exhibits that you may be interested in viewing. The traveling exhibits are updated frequently and some or many of these may be of great interest to you,
There is a mastodon display of bones. Other than that, the only time you would see more is if there is a special exhibition showing.
