Other area AML projects include repairing subsidence, abating underground mine fires and wast coal, closing dangerous mine entrances, reducing dangerous pit highways, and fixing flooded mine pits.
In this vicinity, several historic underground coal fires have been burning for over a century. Such fires state from natural or manmade causes including past mining activities, wildfires, or even through spontaneous combustion. Underground coal fires can pollute the air with toxic gas and smoke emissions, and many emit deadly concentrations of carbon monoxide. These fires can also cause under-ground explosions by igniting methane or other explosive gases.
Kleenburn Recreation Area
In 2009, AML, Sheridan County, and the Wyoming Game and Fish Department partnered to reclaim hazardous conditions left from historic coal mining activity. This resulted in today's Kleenburn Recreation Area. The success of this project was nationally recognized with the 2011 Western Regional Abandoned Mine Land Reclamation Award by the U.S. Department of the Interior Office of Surface Mining.

The Wyoming Abandoned Mine Land Program (AML) works to reclaim areas impact by past mining. Before current mining laws require mine operators to restore the disturbed lands, many miners simply walked away from mines, leaving behind hazards and environmental damage. AML's mission is to mitigate impacts of past mining, alleviate public safety hazards, and repair environmental degradation from abandoned mines of all types.
