Fort Ancient Earthworks & Nature Preserve

6 p.m.–7 a.m.

Every 18.6 years, the moon completes its cycle and reaches its northernmost rising point. This year, the cycle reaches its end—come see the Northernmost Rising Point alignment built into the 2,000-year-old earthworks here at Fort Ancient, marking the end of the current lunar cycle.

The Warren County Astronomical Society will be on site with telescopes for public viewing and to answer questions. The Orionid Meteor shower should be peaking, too.

This is a family-friendly event with activities inside and outside for all ages. The museum and gift shop will be open until 11 p.m.

Admission is free.
