Tàan, sea lion (Prince of Wales) is the 4th largest island in the United States. North Tàan biogeographic province falls entirely within the Alexander geologic terrane, which hosts most of our finest karst landforms—world-class caves and limestone spires like Mount Calder (thumbnail, right). Deeply penetrating fiords nearly divide the island in several places. Tàan and its western satellite islands fall within Southeast’s climatic ‘banana belt.’ Sea level snow is generally ephemeral.
