Mount Eddy is a mountain peak in Siskiyou County, California at about 2,751 m (9,026 ft) above sea level. It is part of Shasta–Trinity National Forest. It sits roughly 13.8 km (8.6 mi) SW of Weed.
Mount Eddy is the highest peak of the Trinity Mountains, a mountain range of the Klamath Mountains System, located in Siskiyou County, and Trinity County in northern California. The mountain is in the Mount Eddy RNA, a Research Natural Area on the Shasta–Trinity National Forest, a unit of the United States Forest Service. The mountain is composed of mesozoic ultramafic rock, predominantly serpentinized peridotite.From the Wikipedia article “Mount Eddy”, licensed under CC BY-SA 4.0.

Golden hour & blue hour by month
Summits catch first and last light — alpenglow can turn rock pink or orange minutes before sunrise and after sunset while valleys stay in shadow.

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 Mount Eddy, the Milky Way core is visible in a dark sky from March through September. June gives the longest window (about 4.5 hours on a moonless night), and the core peaks around 20° 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 ≈ 21.81 mag/arcsec². Aurora needs roughly Kp 8.0+ 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 17% average cloud cover) and December as the cloudiest (65%). 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 peak
- Long lenses compress ridgelines; shoot the peak from several miles away to make it look massive.
- Afternoon thunderstorms are common in summer at high elevations — plan summit hikes for early morning.
- Snow on the summit holds detail best when you expose for the highlights and lift shadows later.
- Alpenglow lasts only a few minutes; set up and focus beforehand.
- Clouds around the summit add drama — a clear blue sky is often the least interesting condition.
- Bring a spare battery — cold weather and long exposures drain them fast.
Season: Early summer keeps snow on the peaks with green valleys below; autumn adds aspen or larch color in many ranges.
Suggested gear: Telephoto lens, Lightweight tripod, Warm layers, Microspikes in shoulder seasons. Work out exposures with the depth of field, ND filter and NPF rule calculators.
