Major Lunar StandstilMost people are familiar with the Moon’s cycle and how its shape changes from crescent to full, and its rising position fluctuates along the horizon. However, unknown to many, the Moon has a much longer cycle called the Major Lunar Standstill (MLS). Every 18-19 years, the Moon’s tilted orbit aligns with the Earth’s axis, bringing it to its farthest Northern or Southern rising positions. At Chimney Rock National Monument, throughout this Major Lunar Standstill alignment, the Moon dramatically rises between the impressive rock pinnacles — Companion Rock and Chimney Rock. It is a timely, but very short-lived event. A thousand years ago, when the Ancient Puebloan people built the Great House and other ceremonial spaces at Chimney Rock, they did so with the purpose, as many of today’s scholars believe, to view this rare and spectacular event.
Two consecutive September night events will be held at the Chimney Rock National Monument Amphitheater to explore the current Major Lunar Standstill at this important Native American site and its relationship to Stonehenge and other worldwide locations. These late-night presentations will feature telescopes and stargazing under the Monument’s majestic dark skies, presentations on astronomy, archaeology and culture from leading experts, Native American music; and, most importantly, a live-streamed viewing of the Moon rising between the natural pinnacles. The MLS season is drawing to a close after 2025. This dramatic moonrise won’t be seen again for 18 years.
Because access to the upper area of the Monument is restricted for safety concerns, these events will be held in the accessible, outdoor Amphitheater near the Visitor Center. And there, after an informative program preceding the event, the long awaited and anticipated rise of the Moon between the pinnacles will be shared via satellite from our crew on the upper mesa.
On Saturday, September 13th, check-in will be at the Visitor Center kiosk from 9:30 pm to 10:30 pm. The Amphitheater program will begin at 10:45 pm for presentations by guest speakers. The live-stream of the moonrise will take place at 11:30 pm. The event will then conclude about 11:45 pm. SOLD OUT
On Sunday, September 14th, check-in will be at the Visitor Center kiosk from 10:30 pm to 11:30 pm. The Amphitheater program will begin at 11:45 pm. The live-streamed moonrise will take place at 12:30 am. The event will then conclude about 12:45 am.
Please dress warmly for these late-night events and consider bringing blankets and cushions for your comfort on the stone seats. No alcohol, smoking/vaping, or drugs — only a “once in a lifetime” experience to be had in our beautiful, natural setting. Come join us in celebrating this rare event. The next Major Lunar Standstill season won’t happen for another 18 years!
