Photo Gallery

The Imuruk Lake volcanic field derives it name from the lake near the center of this NASA Landsat image (with north to the top) of the central Seward Peninsula. The Oligocene-to-Holocene Imuruk monogenetic volcanic field contains around 75 small basaltic vents surrounded by voluminous lava flows. The gray-colored lava flow extending across the left-center portion of this image originated from the Lost Jim cone SW of Imuruk Lake and traveled 35 km to the west. The snow-covered Bendeleben Mountains lie at the bottom of the image.

The Lost Jim lava flow extending to the right across this NASA Landsat image (with north to the top) originated from the Lost Jim cinder cone, SW of Imuruk Lake. The flow was erupted about 1655 years ago and is the only Holocene lava flow of the Imuruk Lake volcanic field. The small 30-m-high cone with a 30-m-wide crater produced a voluminous basaltic lava flow that traveled 35 km to the west and covered an area of about 230 sq km.

Lava flows of the Imuruk Lake volcanic field are seen in this image taken with color infrared film. 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.
