Kanuti series occurs for 30 mi in canyon walls of Kanuti River which later becomes tributary to Koyukuk River, west-central AK. Series includes ultra basic igneous rocks (basalts, basaltic tuffs), tuffs and alteration products (serpentines), some doubtful greenstones and hornstones. Cut by two or three belts of granitic rock. Age is probably Paleozoic based on correlation.
