The white box shows the rough extent of the thermal image on the right. In the thermal image, active breakouts are visible as white and yellow areas. Although active breakouts are absent at the inactive tip of the flow, breakouts are present roughly 450 m (490 yards) behind the tip, and are also scattered further upslope.
