Night Sky Tonight in Monument Valley

The live score above pulls today's forecast and runs it through StarCast's scoring model, factoring 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.

Monument Valley sits in one of the darkest regions of the continental United States, rated Bortle 1 in the surrounding Navajo Nation land. The iconic sandstone mittens and buttes rising 1,000 feet from the valley floor are among the most recognizable silhouettes on earth, and under a Milky Way they're extraordinary. The high desert at 5,500 feet has dry, transparent air and minimal light pollution in every direction. The John Ford Point overlook and the valley floor both face south toward the galactic center during summer.

The galactic core is visible from March through October. Summer new moon nights are the target: the core rises high in the south, the air is dry, and the buttes are fully lit by starlight alone. Photography inside the tribal park requires coordination with Navajo Nation permits; the overlook viewpoints are accessible without permits and give clear southern exposures.
