Mount Humphreys is a mountain peak in Fresno County, California at about 4,081 m (13,389 ft) above sea level. It sits roughly 22 km (13 mi) WSW of West Bishop.
Mount Humphreys is a mountain peak in the Sierra Nevada on the Fresno-Inyo county line in the U.S. state of California. It is the 13th highest peak in California (the highest peak that is not a fourteener), and the highest peak in the Bishop area. The mountain was named by the California Geological Survey of 1873 for Andrew A. Humphreys, the chief engineer of the United States Army at the time.From the Wikipedia article “Mount Humphreys”, 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 Humphreys, the Milky Way core is visible in a dark sky from March through September. June gives the longest window (about 5.5 hours on a moonless night), and the core peaks around 24° 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 ≈ 21.78 mag/arcsec².
Weather & best season
Long-term NASA satellite data for this area show September as the clearest month (about 21% average cloud cover) and December as the cloudiest (54%). July is the warmest month and January 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.
