Kiska Volcano is an active volcano with eruptions every few decades, most recently in 1989. Its summit is approximately 4,000 feet above sea level.
A trip to Kiska Volcano is really roughing it because the island is uninhabited except for research scientists. The nearest settlement (Adak, Alaska) is 250 miles away.
Kiska in WW2
Kiska is a National Historic Landmark. In 1942 the island was invaded and held by the Japanese. Ruins of gun emplacements and other structures are still evident.
Kiska Volcano is surrounded by cliffs on three sides. However, the southern slope is moderate and provides good access for skiing in the spring and early summer.
Kiska is noted as a haven for seabirds and also for its population of rats descended from rodents brought by passing ships over the last two centuries.
If you visit Kiska, remember the island is truly remote. Medical and other facilities are hundreds of miles away. In addition, ordnance left by the Japanese still presents some hazard.
