Mount Lemmon is a mountain peak in Pima County, Arizona at about 2,783 m (9,131 ft) above sea level. It sits roughly 14.3 km (8.9 mi) ESE of Catalina.
Mount Lemmon is a 9,171 ft (2,795 m) mountain in the Santa Catalina Mountains of the US state of Arizona, the highest in the range. It is located in the Coronado National Forest north of Tucson, United States. Mount Lemmon was named for botanist Sara Plummer Lemmon, who trekked to the top of the mountain with her husband and E. O. Stratton, a local rancher, by horse and foot in 1881. Mount Lemmon is also known as Babad Do'ag, or Frog Mountain to the Tohono O'odham. It is home to the southernmost ski destination in the continental United States.From the Wikipedia article “Mount Lemmon”, 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/Phoenix), 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 Lemmon, the Milky Way core is visible in a dark sky from February through October. June gives the longest window (about 6.3 hours on a moonless night), and the core peaks around 29° 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 ≈ 20.52 mag/arcsec².
Weather & best season
Long-term NASA satellite data for this area show June as the clearest month (about 21% average cloud cover) and July as the cloudiest (56%). 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.
