There were always forest fires at Yellowstone but nothing compared to the great fire of 1988. Because of environmental policies created by leftwing massive amounts of fuel (dried out dead wood) lay on the forest floor for years until one day....BOOM!!!!!!
Controlled burning has been proven to be effective in preventing doomsday fire episodes. But you libtards stand in the way. You don't want your "precious wilderness" touched. The California fires were caused by libtards.
