This map reconstructs the location of the Marshall Fire and its smoke plume using data that were publicly available in real-time during the event.

Each indicator appears on the map at the approximate time it became available during the event. This may not be the time that the fire spread to that location.

The map also includes "real-time" wind speed and direction over the affected area.
