Explorations Academy, an independent high school in Bellingham, is hosting its fourth annual “Great Mystery” citywide scavenger hunt from April 15 to May 6 to raise money for scholarships and financial aid.

Each participating team receives by mail weekly clues related to Bellingham’s history and landscape. Teams use the mailings to crack weekly puzzles—with winners receiving prizes—and find new clues that lead up to a final, culminating mystery after four weeks.

Participation costs $50 per team, and teams can register for family or “super slueth” game levels.

To register, and to find more information, visit www.thegreatmystery.info, or contact Explorations Academy at 360-671-8085, or info@explorationsacademy.org.
