Chimney Rock National Monument Major Lunar Standstill Closures

Release Date: Jul 10, 2023

Temporary closures will impact recreation areas beginning July 15^th, 2023

Chimney Rock National Monument CO., July 10, 2023— Chimney Rock National Monument will be closed to public access during Major Lunar Standstill occurrences to provide for employee, partner, and public safety. The Major Lunar Standstill (MLS) is an astronomical event that occurs every 18.6 years. It is visible from Chimney Rock National Monument where the moon aligns between the two sandstone spires: Chimney Rock and Companion Rock. The rising time is visible for a few days throughout the year over the course of three years. Full details of the closure are in the attached Forest Order and map.

In the past, visitors could view the Major Lunar Standstill from a two-story fire lookout tower. The tower was removed in 2010 and as a result there is no longer a modern structure or location where the moon rising can be viewed safely. Hazards associated with hiking the strenuous upper mesa trail in the dark, significant 1,000-foot cliffs on both sides of the trail, and the lack of adequate safety lighting and cliff barriers have been determined to be beyond the agency’s ability to mitigate.

In light of these hazards, and the intense public interest in viewing the Major Lunar Standstill, the Forest Supervisor has determined a closure order is necessary to protect public safety, as well as the safety of agency and academic partners who will be permitted in limited numbers to access the viewing area for the purpose of scientific research and videography.

The Forest Service and partners are discussing opportunities to share the event via other platforms such as live streaming, still photography and/or video recording in 2024-2025. No public access will be allowed in the monument after hours of operation during periods and nights surrounding the rising events. Closure of the monument during these periods will be enforced.
