The Observatory operates with support from a small group of volunteers—all ages and stages— throughout the year. We currently have four high school students who contribute on a regular basis by working in the gift shop, leading tours, helping with cleaning and landscaping and other projects. We also support high school and college interns during the summer who receive training on all aspects of the Observatory operations including Observing, Tours, Educational Programs, Gift Shop Management, Building Maintenance and Landscape Work. These internships are mutually beneficial as the Observatory gets crucial work done and the students learn a variety of skills and develop understanding about the history of Blue Hill. They also gain experience by participating in the one-day corporate volunteer events hosted by the Observatory.
