Description
From Wood and Kienle (1990): "The Koyuk-Buckland monogenetic volcano field is the largest basalt field in Alaska, and among the least known. It is mostly contained within the Candle quadrangle. The field consists of basalt flows, with local aggregate thickness of 150 m, which have erupted from ~46 cinder cones and small shield volcanoes. Most of the basalts are flat-lying, but some have been gently folded. The age of the basalts is unknown, but they are thought to be correlative with the Imuruk basalt field 100 km to the west. The composition of the field is also unknown, but the presence of ultramafic nodules suggests that at least some flows are alkaline."
