Located in Aleutians West Census Area, Alaska, Kasatochi Island is a volcano.

Kasatochi Island (Aleut: Qanan-tanax̂; Russian: Касаточий остров), also known as Kasatochi volcano, is an active stratovolcano and part of the Andreanof Islands subgroup of the Aleutian Islands of southwestern Alaska. On 7 August 2008, Kasatochi began erupting explosively with an ash plume reaching 45,000 feet (14,000 m). The eruption lasted for 24 hours and destroyed most life on the island. Since the eruption, it has been the site of research on the primary succession of species back onto the island. It currently does not support any consistent human population. Kasatochi Island is a member of the Aleutian Islands, which lie above a narrow ridge that separates the Bering Sea from the North Pacific. It lies at the Atka Pass northwest of the western tip of Atka Island and east of Great Sitkin Island. It is at 52.177° N latitude and 175.508° W longitude, with a summit elevation of...From the Wikipedia article “Kasatochi Island”, licensed under CC BY-SA 4.0.

Golden hour & blue hour by month

Volcanic cones and lava fields have strong shapes that read well in side-light; dark basalt needs careful exposure.

Local time (America/Adak), 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

At this latitude the summer nights are too short or too bright for the Milky Way core to stand high in true darkness; aim for star trails or the aurora.

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 6.5+ to show low on the northern horizon here.

Weather & best season

Long-term NASA satellite data for this area show October as the clearest month (about 83% average cloud cover) and June as the cloudiest (96%). August 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 volcano

  • Long lenses from 20–60 miles away make large stratovolcanoes dominate the horizon.
  • Check local volcanic activity notices and area closures before visiting.
  • Snow-capped volcanoes reflect alpenglow at sunrise — shoot from a lake or meadow for a reflection.
  • Lava rock is sharp and unstable; stay on trails.
  • Scout in daylight if you plan to shoot at night or before sunrise.

Season: Summer for high trails; winter and spring for snowy cones viewed from below.
