Night Sky Tonight in Chaco Culture

The live score above pulls today's forecast and runs it through StarCast's scoring model, which factors in cloud cover, moon illumination, Bortle class, humidity, and atmospheric transparency. Above 70 is an excellent night. Below 40, conditions are poor. The score updates daily.

Chaco Culture National Historical Park in northwestern New Mexico combines two things that rarely coexist: world-class dark skies and ancient ruins foreground. The Ancestral Puebloans who built Chaco were astronomers themselves, aligning their great houses with solar and lunar cycles. The park holds Gold Tier International Dark Sky Park status with Bortle 1 to 2 ratings. Pueblo Bonito, the largest great house, is one of the most photogenic night sky foregrounds in the Southwest. The 13-mile dirt access road keeps casual visitors away, meaning the park is genuinely quiet on most nights.

The galactic core is visible at Chaco from March through October. The park hosts regular astronomy programs and night sky events tied to the solstices and equinoxes, connecting modern stargazing to the astronomical traditions of the Ancestral Puebloans. Spring and fall bring the clearest skies and most comfortable temperatures for overnight shooting.
