Sonora Pass (el. 9,624 ft. / 2,933 m.) is a mountain pass in the Sierra Nevada in California. It is the second-highest pass with a road in California and in the Sierra Nevada. It is 321 feet (98 m) lower than Tioga Pass to the south. State Route 108 traverses the pass, as does the Pacific Crest Trail.From the Wikipedia article “Sonora Pass”, licensed under CC BY-SA 4.0.

Sunrise & sunset directions

At Sonora Pass the sunrise point swings a long way through the year: about 59° (ENE) at the June solstice and 120° (ESE) in late December. Sunset moves from 301° (WNW) in June to 240° (WSW) in December, and the midday sun climbs to 75° in summer but only 28° in winter.

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 Sonora 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 23° 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 ≈ 21.68 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

  • 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.
  • 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.
  • Shoot RAW to keep the most latitude for high-contrast sunrise and sunset scenes.

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.
