Vulcão Monte Spurr
Um dos vulcões ativos mais próximos de Anchorage, a cerca de 125 km a oeste. A erupção de 1992 cobriu a cidade de cinzas e fechou o aeroporto. Em 2024 começou um novo período de agitação, com aumento de sismos, emissões de gás e elevação do solo, e em 2025 os cientistas avisaram que uma erupção era provável.
