Chimney Rock National Monument Apr 2026

Chimney Rock is considered a "Chacoan outlier," a satellite community of the vast Chaco Canyon civilization centered in New Mexico, roughly 100 miles to the south. It represents the highest elevation of any known Chacoan site.

Every 18.6 years, the moon reaches its northernmost rising point on the horizon. From the vantage point of the Great House, the moon appears to rise directly between Chimney Rock and Companion Rock .

Managed for archaeological protection and public education, the monument's management plan focuses on:

Chimney Rock National Monument is more than a collection of ruins; it is a testament to the scientific and spiritual sophistication of the Ancestral Pueblo People. Its unique geographic location and astronomical alignments provide a window into how ancient cultures integrated their lives with the rhythms of the cosmos.

The alignment of buildings and natural features suggests the site was also used to mark the longest day of the year, aiding in agricultural planning for crops like corn, beans, and squash. 4. Preservation and Management
