Argentine Peak — a mountain peak in Clear Creek County, Colorado at about 4,186 m (13,734 ft) above sea level — is a popular subject for landscape photographers. The nearest town is Georgetown, about 12.5 km (7.8 mi) away (Argentine Peak lies SSW of town).
Argentine Peak is a high mountain summit in the Front Range of the Rocky Mountains of North America. The 13,743-foot (4,189 m) thirteener is located in Arapaho National Forest, 8.5 miles (13.6 km) southwest by south (bearing 211°) of Georgetown, Colorado, United States. The summit lies on the Continental Divide between Clear Creek and Summit counties. The peak is approximately 1 mile south of Argentine Pass. The peak and the pass take their names from the Argentine District, Colorado's first major silver mining district. Argentum is the Latin word for silver, for the silver ore found in the area.From the Wikipedia article “Argentine Peak”, licensed under CC BY-SA 4.0.

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
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/Denver), 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 Argentine Peak, the Milky Way core is visible in a dark sky from March through September. June gives the longest window (about 5.0 hours on a moonless night), and the core peaks around 22° above the southern horizon. Our light-pollution model puts the sky at about Bortle 3 (rural sky), 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: 3 Bortle 3 — Rural sky. Some light domes sit on the horizon, but the Milky Way still looks complex overhead. Modeled zenith brightness ≈ 21.29 mag/arcsec². Aurora needs roughly Kp 7.5+ to show low on the northern horizon here.
Weather & best season
Long-term NASA satellite data for this area show September as the clearest month (about 44% average cloud cover) and April as the cloudiest (64%). 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
- 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.
- Shoot RAW to keep the most latitude for high-contrast sunrise and sunset scenes.
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.
