Thermal infrared image showing the likely base of a new lava dome in the crater of Redoubt Volcano. While the dome is completely obscured by ash and steam in the visible photographs, the heat of the new lava can often be detected by the thermal infrared camera. The image also shows a trail of hot block and ash confined to the canyon below the summit.
