How about creating a "dig site" scavenger hunt for your boyfriend? You can scatter clues and artifacts around your home, and your boyfriend can use his archaeological skills to uncover each new cache of goodies. Some ideas for artifacts could include small replicas of ancient tools, pottery or coins. At the end of the scavenger hunt, you can reveal a special gift, such as a personalized archaeological field guide or an artifact replica. You could also consider booking a guided tour of a local archaeological site or museum as a unique outing for the two of you to enjoy together.
Or you can get him a star map with the date of your anniversary.
