Owyhee River Wilderness — a wilderness area in Owyhee County, Idaho — is a popular subject for landscape photographers. The nearest town is Mountain Home, about 131 km (81 mi) away (Owyhee River Wilderness lies SW of town).
The Owyhee River Wilderness is located on the high basalt plateaus of Owyhee County in southwestern Idaho in the western United States. The wilderness area is named after and protects the upper Owyhee River, its tributaries, and the surrounding desert canyon landscape. Whitewater rafting is a popular recreational activity in this wilderness area. Managed by the Bureau of Land Management, it is the second-largest U.S. Wilderness Area that is not located within a National Forest, National Park, or National Wildlife Refuge. The BLM's Black Rock Desert Wilderness, located within Black Rock Desert – High Rock Canyon Emigrant Trails National Conservation Area, is larger. About 67.3 miles (108.3 km) of the Owyhee River is classified as a wild river.From the Wikipedia article “Owyhee River Wilderness”, licensed under CC BY-SA 4.0.

Milky Way & night sky
From Owyhee River Wilderness, the Milky Way core is visible in a dark sky from March through September. June gives the longest window (about 4.2 hours on a moonless night), and the core peaks around 19° 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 ≈ 21.92 mag/arcsec². Aurora needs roughly Kp 7.0+ 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 30% 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.
