Abandoned campfires are one of the leading causes of forest fires. Not all of these fires were intentionally left smoldering. Campfires heat the ground underneath them hot enough to reignite anything combustible in your firepit hours later. No one wants to be “that guy/girl” so use lots of water or dirt to thoroughly smother your campfire when you are done with it. As a rule of thumb, you should be able to put your hand comfortably on the ground in your fireplace before you leave.
