Located in Lincoln County, Wyoming, Seedskadee National Wildlife Refuge is a national wildlife refuge. The nearest town is Green River, about 48 km (30 mi) away (Seedskadee National Wildlife Refuge lies NW of town).
Seedskadee National Wildlife Refuge is a National Wildlife Refuge of the United States located in western Sweetwater County in the state of Wyoming. It covers 26,400 acres (106 km2) managed by the U.S. Fish and Wildlife Service, an agency within the U.S. Department of the Interior. The Shoshone people inhabited the region since the year 1300. The name Seedskadee is derived from the Shoshone language word sisk-a-dee-agie, which means "river of the prairie hen". The area was first visited by white explorers in 1811 and was later a crossroads for the Oregon and Mormon Trails; many of the original wagon tracks left by early pioneers can still be seen. The refuge includes 36 miles (56 km) of the Green River, which is a water source for shrubs and cottonwoods in an otherwise arid region. The refuge was established in 1965 to mitigate wildlife habitat loss resulting from the construction of...From the Wikipedia article “Seedskadee National Wildlife Refuge”, licensed under CC BY-SA 4.0.

Milky Way & night sky
From Seedskadee National Wildlife Refuge, the Milky Way core is visible in a dark sky from March through September. June gives the longest window (about 4.3 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 2 (typical truly dark site), which is excellent for astrophotography.

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 ≈ 21.89 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 September as the clearest month (about 40% average cloud cover) and February as the cloudiest (67%). July is the warmest month and January the coldest, which matters for gear, snow access and how long batteries last at night.

Photography tips for this national wildlife refuge
- Fast shutter speeds (1/2000 s+) freeze wingbeats; raise ISO rather than lose the shot.
- Migration peaks bring the largest concentrations — see the birding calendar for this state.
- Use auto-loop roads as mobile blinds; animals often tolerate vehicles more than people on foot.
- Stay on designated routes and keep a respectful distance — if an animal changes behavior, you are too close.
- A 400–600 mm lens (or a crop body) is the usual tool for birds.
- Bring a spare battery — cold weather and long exposures drain them fast.
Season: Spring and autumn migration are the highlights; winter brings waterfowl to many southern refuges.
Suggested gear: Telephoto lens (400 mm+), Bean bag for car window, Binoculars. Work out exposures with the depth of field, ND filter and NPF rule calculators.
Permits, drones & access
Drones: Launching or landing drones on National Wildlife Refuge lands generally requires a special use permit from the refuge manager, and wildlife disturbance rules apply everywhere.
