Nelson Island description and information

From Wood and Kienle (1990): "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."
