How about creating a customized shadow box to display her favorite arrowheads that she has collected? You could also include a map of the locations where she found them, as well as some information about the history of arrowheads. Another idea could be to get her a book on arrowheads and the history of their use in various cultures. You could also consider getting her a high-quality magnifying glass or a metal detector to make the search for arrowheads even more exciting!
Or you can get her a star map with an important date you share.
