I got an early start on a loop hike starting at First Water TH, then around the Dutchman's trail up to Bull Pass, lunch, then back on Black Mesa to Garden Valley and finishing up on Second Water. As expected, there were a ton of people out today.
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.
