The name of this group of eight volcanic islands — which is part of a 2,300-kilometer-long chain of islands in the northern Pacific — was translated from the Russian name “Ostrova Chetyre Soposhnye."
The names of the three Holocene-aged volcanoes pictured were first recorded as Chagulax, Chuginadax and Ulyagan in 1834 by a Russian Orthodox priest.
When the island group was visited by the U.S. Coast and Geodetic Survey in the 1890s, the center volcano (seen with steam rising from its peak), which is the tallest and most volcanically active in the group, was renamed for the sitting president.
