Thermal map of flow field

This map is similar to the map above but shows a thermal map over the Episode 61g lava flow. Cooler colors (blue and green) show cooled, inactive portions of the flow surface. Hot colors (red and orange) show areas of active surface breakouts.

The thermal map was constructed by stitching many overlapping oblique thermal images collected by a handheld thermal camera during a helicopter overflight of the flow field.
