Ice caves — a cave in Lincoln County, Idaho at about 1,391 m (4,564 ft) above sea level — is a lesser-known subject for landscape photographers. The nearest town is Shoshone, about 25 km (16 mi) away (Ice caves lies NNE of town).
Sunrise & sunset directions
At Ice caves the sunrise point swings a long way through the year: about 56° (NE) at the June solstice and 122° (ESE) in late December. Sunset moves from 304° (NW) in June to 238° (WSW) in December, and the midday sun climbs to 70° in summer but only 23° in winter.

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
Caves are lit artificially — show caves have fixed lighting, so a fast lens and high ISO beat flash, which flattens formations.

Local time (America/Boise), 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 Ice caves, the Milky Way core is visible in a dark sky from March through September. June gives the longest window (about 3.8 hours on a moonless night), and the core peaks around 18° 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 ≈ 21.89 mag/arcsec². Aurora needs roughly Kp 6.5+ to show low on the northern horizon here.
Weather & best season
Long-term NASA satellite data for this area show July as the clearest month (about 30% average cloud cover) and December as the cloudiest (64%). 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 cave
- Many show caves restrict tripods on tours; ask in advance or bring a small beanbag.
- Use manual focus with focus peaking in low light.
- Never touch formations — skin oils stop their growth.
- Follow White-nose Syndrome decontamination rules where posted to protect bats.
- Shoot RAW to keep the most latitude for high-contrast sunrise and sunset scenes.
Season: Cave interiors stay at a constant temperature year-round; summer tours fill up, so book ahead.
Suggested gear: Fast lens (f/1.8–f/2.8), High-ISO camera, Small beanbag. Work out exposures with the depth of field, ND filter and NPF rule calculators.
