The Pleistocene Nangelaquishan cinder cone, capped by a 500-m-wide flat-bottomed crater, is one of 14 cones forming the Wudalianchi volcanic field in Manchuria, NE China. The cinder cones, four of which are Holocene in age, show a preferred alignment along three parallel NE-SW trends. The Wudalianchi volcanic field was named for five scenic lakes dammed by lava flows during a 1719-21 eruption, which formed two new cinder cones and produced a 65 sq km lava field.
