We drove around and explored what we could of Canyon de Chelly. Went on the one day they don't have guides available, but we had a great time taking pictures anyway. Started at Spider Rock Overlook and made our way from there to each stop until the Massacre Cave Overlook. I don't remember there being too much to see except at Spider Rock, White House, and Antelope Ruins. It was pretty cold outside and the roads, although well-maintained, were still somewhat icy and snowy. Didn't spend too much time at any of the sites beyond those three.
A campfire must be extinguished by drowning it with water, stirring with a shovel, and repeating that process until the campfire is cold to the touch. A campfire is still a danger if it has any trace of heat, and must not be left or abandoned. Wildfires can begin by abandoned campfires that rebuild heat on windy days and then blowing embers ignite surrounding grasses and brush.
