From Wood and Kienle (1990) [1] : "Reconnaissance geologic mapping of Nelson Island revealed basaltic lava flows ~30 m thick dipping gently eastward. The topography of the island suggests it is highly dissected and probably late Tertiary rather than Quaternary in age. Younger looking isolated cones are evident to the south at Ingariak Hills, Tern Mountain, Cheching Mountain, and benchmark Kinia."

Name Origin

Nelson Island was named in 1880 by Henry Gannet, for Edward William Nelson, who spent about five years in this area as an observer for the U.S. Signal Service and a collector for the Smithsonian Institution (Orth, 1971).
