Realized today that it has been 80 days since my last hike and I really needed to get out again. I followed the creek, and the "trails" that intermittently appear and disappear on either side of it farther than any of my previous excursions. I ended up stopping just short of where Box Springs trail ends at the creek. In my opinion it is actually easier and more scenic to access the pools at Box Springs via this route instead of following Box Springs trail, which is extremely overgrown.
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.
