Detailed Description

A comparison of a normal photograph with a thermal image. The white box shows the approximate extent of the thermal image. The elevated temperatures (white and yellow areas) around the flow front indicate that significant activity is focused at the front, driving its forward movement. In addition, a slow-moving lobe was active upslope of Cemetery Rd. Farther upslope, scattered breakouts persist in the wider portion of the flow.
