Golden hour & blue hour by month
Arches glow when reflected light bounces off nearby rock — the underside of an arch often turns bright orange just after sunrise or before sunset.

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 Murl Emery Arch, the Milky Way core is visible in a dark sky from February through October. June gives the longest window (about 5.7 hours on a moonless night), and the core peaks around 25° above the southern horizon. Our light-pollution model puts the sky at about Bortle 4 (rural / suburban transition), 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: 4 Bortle 4 — Rural / suburban transition. Light domes are visible in several directions; the Milky Way is clear but lacks detail near the horizon. Modeled zenith brightness ≈ 21.15 mag/arcsec².
Weather & best season
Long-term NASA satellite data for this area show June as the clearest month (about 17% average cloud cover) and December as the cloudiest (43%). 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 natural arch
- Midday sun creates hard shadows, but can light the underside through reflection in narrow canyons.
- Frame distant features through the opening of the arch for a natural window.
- At night, arches make classic Milky Way foregrounds; low-level lighting or blue hour exposures keep the rock detailed.
- Use a wide lens and get close to emphasize the span against the sky.
- Never climb on arches; many are fragile and climbing is prohibited on park lands.
- Shoot RAW to keep the most latitude for high-contrast sunrise and sunset scenes.
Season: Spring and autumn offer mild temperatures in desert arch country; summer heat is extreme at midday.
Suggested gear: Ultra-wide lens, Tripod, Headlamp, Plenty of water. Work out exposures with the depth of field, ND filter and NPF rule calculators.
