Shuttle hike starting at Cholla TH. Watched some squirrels (VERY exciting...) until my sister made it to the top. Also watched some guy throw what was left of his smoldering cigarette on the ground. It was about an hour before I started to head down. Finally found the "cave" I've read about, too.
Last time I was here my time was 2 hours and 10 minutes roundtrip. I think I've improved quite a bit.
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.
