From Wood and Kienle (1990) [1] : "Davidof, Khvostof, and nearby small islands Pyramid and Lopy rise 100 m above a submarine platform as the remnants of a collapsed caldera. This 'Aleutian Krakatoa' is thought to have formed during the late Tertiary, but the volcano is essentially unstudied. The islands are covered by vegetation; however lava flows can be recognized on aerial photographs. Lavas and pyroclastic layers form the islands, and rocks on the northern part of Davidof and Lopy Island are intensely hydrothermally altered."

Name Origin

Davidof Island's name was published by Admiral von Krusenstern (1827), for the Russian naval officer Gavriil Ivanovich Davidov, who, with N.A. Khvostov, explored Alaska during 1802-1804. Admiral von Kruzenstern applied the name "I[sle] Dawydoff" to Segula Island, but in 1855 the U.S. Navy Hydrographic Office clarified the size and position of both Davidof and Segula Islands and reapplied the names (Orth, 1971).
