I'm glad I had not run out of steam to press on to Siphone Draw after a disappointing Hierogylphics Canyon and Treasure Loop trail. I think I was paying too much attention to the "introductory" phrasing when looking into my first Superstition hikes. This is an enjoyable quick hike if you live in the area... but if traveling from far... I suggest this as an anecdote to an otherwise jam-packed day full of serious hiking!
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.
