Vulcano Monte Spurr
Uno dei vulcani attivi più vicini ad Anchorage, circa 125 km a ovest. L'eruzione del 1992 coprì la città di cenere e chiuse l'aeroporto. Nel 2024 è iniziato un nuovo periodo di agitazione con aumento dei terremoti, delle emissioni di gas e del sollevamento del suolo, e nel 2025 gli scienziati hanno avvertito che un'eruzione era probabile.
