Gros Ventre Wilderness — a wilderness area in Teton County, Wyoming — is a rewarding subject for landscape photographers. It sits roughly 28 km (18 mi) E of Jackson.
The Gros Ventre Wilderness ( groh-VAHNT) is located in Bridger-Teton National Forest in the U.S. state of Wyoming. Most of the Gros Ventre Range is located within the wilderness. U.S. Wilderness Areas do not allow motorized or mechanized vehicles, including bicycles. Although camping and fishing are allowed with proper permit, no roads or buildings are constructed and there is also no logging or mining, in compliance with the 1964 Wilderness Act. Wilderness areas within National Forests and Bureau of Land Management areas also allow hunting in season. Etymology : In French, Gros Ventre means big belly / big stomach.From the Wikipedia article “Gros Ventre Wilderness”, licensed under CC BY-SA 4.0.

Milky Way & night sky
From Gros Ventre Wilderness, the Milky Way core is visible in a dark sky from March through September. June gives the longest window (about 3.8 hours on a moonless night), and the core peaks around 18° above the southern horizon. Our light-pollution model puts the sky at about Bortle 1 (excellent dark-sky 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: 1 Bortle 1 — Excellent dark-sky site. The Milky Way casts faint shadows; zodiacal light and airglow are obvious. Modeled zenith brightness ≈ 21.91 mag/arcsec². Aurora needs roughly Kp 6.0+ to show low on the northern horizon here.
Weather & best season
Long-term NASA satellite data for this area show July as the clearest month (about 38% average cloud cover) and December as the cloudiest (71%). July is the warmest month and January the coldest, which matters for gear, snow access and how long batteries last at night.
