Background
The Oligocene-to-Holocene Imuruk monogenetic volcanic field in the central Seward Peninsula north of the Bendeleben Mountains contains around 75 small basaltic vents surrounded by voluminous lava flows. The largest and most recent vent is the Lost Jim cone, a 30-m-high cinder cone near Imuruk Lake that produced the only Holocene lava flow of the Imuruk field. The massive Lost Jim lava flow, erupted about 1655 years ago, extends 35 km west and 9 km north of the vent and covers about 230 sq km. The next youngest flow, the late-Pleistocene Camille lava flow, traveled 39 km from its vent.---
