Located in Alpine County, California, Carson Pass is a mountain pass at about 2,619 m (8,593 ft) above sea level. It is part of Eldorado National Forest. The nearest town is South Lake Tahoe, about 27 km (17 mi) away (Carson Pass lies S of town).
Carson Pass is a mountain pass on the crest of the central Sierra Nevada, in the Eldorado National Forest and Alpine County, eastern California. The pass is traversed by California State Route 88. It lies on the Great Basin Divide, with the West Fork Carson River on the east and the South Fork American River on the west. The historic pass was a point on the Carson Trail during the California Gold Rush and was used for American Civil War shipping to California until the completion of the First transcontinental railroad. The Pacific Crest Trail traverses the Carson Pass summit, which has California Historical Landmark #315 at CA 88 postmile 6.09 where Kit Carson carved his name into a tree.From the Wikipedia article “Carson Pass”, 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.

Local time (America/Los Angeles), including daylight saving time. Golden hour runs from about −4° to +6° solar altitude, so the morning golden hour begins during blue hour, before sunrise.
Milky Way & night sky
From Carson Pass, the Milky Way core is visible in a dark sky from March through September. June gives the longest window (about 5.2 hours on a moonless night), and the core peaks around 22° 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 ≈ 21.5 mag/arcsec².
Weather & best season
Long-term NASA satellite data for this area show August as the clearest month (about 20% average cloud cover) and March as the cloudiest (60%). July is the warmest month and December the coldest, which matters for gear, snow access and how long batteries last at night.

Photography tips for this mountain pass
- 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.
- Bring a spare battery — cold weather and long exposures drain them fast.
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.
