Bisti/De-Na-Zin Wilderness is a wilderness area in San Juan County, New Mexico. The nearest town is West Hammond, about 42 km (26 mi) away (Bisti/De-Na-Zin Wilderness lies S of town).
The Bisti/De-Na-Zin Wilderness is a 45,000-acre (18,000 ha) wilderness area located in San Juan County in the U.S. state of New Mexico. Established in 1984, the Wilderness is a desolate area of steeply eroded badlands managed by the Bureau of Land Management, except three parcels of private Navajo land within its boundaries. The John D. Dingell Jr. Conservation, Management, and Recreation Act, signed March 12, 2019, expanded the Bisti/De-Na-Zin Wilderness by approximately 2,250 acres. Translated from the Navajo word Bistahí, Bisti means "among the adobe formations". De-Na-Zin, from Navajo Dééł Náázíní, translates as "Standing Crane". Petroglyphs of cranes have been found south of the Wilderness. It is on the Trails of the Ancients Byway, one of the designated New Mexico Scenic Byways.From the Wikipedia article “Bisti/De-Na-Zin Wilderness”, licensed under CC BY-SA 4.0.

Milky Way & night sky
From Bisti/De-Na-Zin Wilderness, the Milky Way core is visible in a dark sky from February through October. June gives the longest window (about 5.7 hours on a moonless night), and the core peaks around 25° above the southern horizon. Our light-pollution model puts the sky at about Bortle 2 (typical truly dark site), which is excellent for astrophotography.

Window when the galactic core is at least 10° high during astronomical darkness on the 15th of each month. Pick nights within a few days of the new moon. Plan exact nights with the Milky Way planner.
Estimated sky darkness: 2 Bortle 2 — Typical truly dark site. The summer Milky Way shows rich structure; clouds look like black holes in the stars. Modeled zenith brightness ≈ 21.87 mag/arcsec².
Weather & best season
Long-term NASA satellite data for this area show June as the clearest month (about 29% average cloud cover) and December as the cloudiest (53%). July is the warmest month and January the coldest, which matters for gear, snow access and how long batteries last at night.
