Located in Chittenden County, Vermont, Appalachian Gap is a mountain pass. It sits roughly 10.2 km (6.3 mi) E of Starksboro.
The Appalachian Gap is a mountain pass in the Green Mountains of Vermont. The highest point of the pass is located in Chittenden County, about 0.2 mi (0.32 km) west of the boundary between Chittenden and Washington County. The pass is in the Camel's Hump State Park. On the east side, Appalachian Gap is drained by Mill Brook, which drains into the Mad River, the Winooski River, and into Lake Champlain. To the west, the gap is drained by Beaver Meadow Brook, which drains into the Huntington River, another tributary of the Winooski River. Lake Champlain drains into the Richelieu River in Quebec, thence into the Saint Lawrence River, and into the Gulf of Saint Lawrence.From the Wikipedia article “Appalachian Gap”, licensed under CC BY-SA 4.0.

Golden hour & blue hour by month
Mountain passes sit above valleys, so they reward sunrise and sunset with layered ridges, valley fog and long shadows.

Milky Way & night sky
From Appalachian Gap, the Milky Way core is visible in a dark sky from March through September. June gives the longest window (about 3.5 hours on a moonless night), and the core peaks around 17° above the southern horizon. Our light-pollution model puts the sky at about Bortle 3 (rural sky), good enough for detailed Milky Way images.

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: 3 Bortle 3 — Rural sky. Some light domes sit on the horizon, but the Milky Way still looks complex overhead. Modeled zenith brightness ≈ 21.61 mag/arcsec². Aurora needs roughly Kp 4.5+ 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 57% average cloud cover) and December as the cloudiest (81%). 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 mountain pass
- Weather changes fast at elevation; carry layers even in summer.
- Summit pull-outs often face one direction; use the sun azimuth table to see whether sunrise or sunset suits the view.
- Wildflowers bloom late at pass elevations — often July to early August in the Rockies and Sierra.
- Check road status before driving: many high passes close seasonally or after storms.
- Look for the road itself as a leading line — switchbacks from above make strong compositions.
- Check road and trail conditions with the managing agency before you go.
Season: Summer and early autumn are the main season; winter visits depend on plowing and avalanche conditions.
Suggested gear: Telephoto lens, Tripod, Warm layers, Road-condition app. Work out exposures with the depth of field, ND filter and NPF rule calculators.
