We enjoyed this hike as it was the first time we have come across old mine workings, And I mentioned to my Wife that it was like the film "The Hills Have Eyes". After the open mine We carried on up the water erroded trail. We had the place to ourselves and enjoyed the views and different hike.
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.
