Mono Pass — a mountain pass in Tuolumne County, California at about 3,238 m (10,623 ft) above sea level — is a rewarding subject for landscape photographers. It is part of Ansel Adams Wilderness. It sits roughly 31 km (19 mi) NW of Mammoth Lakes.
Mono Pass is a mountain pass, just outside Yosemite National Park, near the region of Tuolumne Meadows. Mono Pass is between Mount Gibbs and Mount Lewis. There is another pass also named Mono less than 40 miles away in the Rock Creek/Little Lakes Valley area. Both Mono Passes are in the Inyo National Forest. The Mono Pass in the Rock Creek/Little Lakes Valley area is accessed by the Mosquito Flats Trailhead rather than the Mono Pass Trailhead in Yosemite National Park. Mono Pass is on the Great Basin Divide, which demarcates the Great Basin. The latter is the largest area in North America from which waters don't drain towards an ocean. Tioga Pass, the east entrance to the national park on highway 120, 4.5 miles north-northwest, is likewise on the Great Basin Divide.From the Wikipedia article “Mono Pass”, licensed under CC BY-SA 4.0.

Azimuth is measured clockwise from true north (90° = east, 270° = west). Computed for 2026; values change by less than a degree from year to year.
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 Mono Pass, the Milky Way core is visible in a dark sky from March through September. June gives the longest window (about 5.3 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 2 (typical truly dark 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: 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 ≈ 21.75 mag/arcsec².
Weather & best season
Long-term NASA satellite data for this area show August as the clearest month (about 15% average cloud cover) and December as the cloudiest (54%). 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
- 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.
Permits, drones & access
Drones: Drones may not take off from or land in federally designated wilderness, where mechanized equipment is prohibited under the Wilderness Act.
