Mount Augusta is a mountain peak in Yakutat City and Borough, Alaska at about 4,201 m (13,783 ft) above sea level.
Mount Augusta, also designated Boundary Peak 183, is a high peak in the US state of Alaska and the Canadian territory of Yukon. It lies about 25 km (16 mi) south of Mount Logan and 25 km east of Mount Saint Elias, respectively the first and second highest mountains in Canada. Mount Augusta forms the eastern end of the long ridge of which Mount Saint Elias is the center and highest point. The Seward Glacier starts to the north of the peak, separating it from Mount Logan, and then flows around the east side of the peak, forming the gap between Augusta and the peaks surrounding Mount Cook. It then continues south to join the Malaspina Glacier.From the Wikipedia article “Mount Augusta”, 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/Whitehorse), 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
The Milky Way's bright core (in Sagittarius) barely clears the southern horizon at this latitude, so focus on winter Milky Way, aurora or star trails instead.

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: 1 Bortle 1 — Excellent dark-sky site. The Milky Way casts faint shadows; zodiacal light and airglow are obvious. Modeled zenith brightness ≈ 21.95 mag/arcsec². Aurora needs roughly Kp 0.0+ to show low on the northern horizon here.
Weather & best season
Long-term NASA satellite data for this area show March as the clearest month (about 64% average cloud cover) and August as the cloudiest (87%). July is the warmest month and March the coldest, which matters for gear, snow access and how long batteries last at night.

Photography tips for this mountain peak
- 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.
- 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.
- 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.
