Located in Los Angeles County, California, Mount Lowe is a mountain peak at about 1,699 m (5,574 ft) above sea level. It sits roughly 5.2 km (3.2 mi) NNE of Altadena.
Mount Lowe is a mountain on the southern fold of the San Gabriel Mountains. Originally named Oak Mountain, it was renamed for Professor Thaddeus S.C. Lowe, who is credited for being the first person to set foot on and plant the American flag at its peak, and who built the Mount Lowe Railway to its foot in 1896. The record of the naming was made official by Andrew McNally, the famous Chicago map printer and summertime resident of Altadena, who promised to print "Mount Lowe" on all his maps. Mt. Lowe was established as an alternate route for the Mount Lowe Railway when attempts to procure rights of way to the more prominent Mount Wilson had failed.From the Wikipedia article “Mount Lowe (California)”, 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 Lowe, the Milky Way core is visible in a dark sky from February through October. June gives the longest window (about 6.0 hours on a moonless night), and the core peaks around 27° above the southern horizon. Our light-pollution model puts the sky at about Bortle 7 (suburban / urban transition), so expect visible sky glow; drive away from towns for better results.

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: 7 Bortle 7 — Suburban / urban transition. The whole sky has a grey-white glow; the Milky Way is invisible to the eye. Modeled zenith brightness ≈ 18.46 mag/arcsec².
Weather & best season
Long-term NASA satellite data for this area show August as the clearest month (about 14% average cloud cover) and January as the cloudiest (42%). 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
- 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.
- Photograph the peak from a lake, meadow or ridge at sunrise when the face that looks east lights up first.
- Long lenses compress ridgelines; shoot the peak from several miles away to make it look massive.
- Scout in daylight if you plan to shoot at night or before sunrise.
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.
