 In early August, fire managers reached a conclusion that the fires would not likely expand much further, due to a lack of fuel, and the Director of the National Park Service declared on August 11 that the fires were contained.When this optimistic announcement was followed by Black Saturday on August 20, and the fire that threatened the Old Faithful complex in early September, the media were again highly critical of the park service and their policies.As a result of research conducted after the fires, a new fire management plan for Yellowstone was implemented in 1992.
