Selecting a Leave No Trace fire site.
At established sites, use existing fire rings. These help concentrate the impact associated with fires and keep surrounding areas in more natural condition. Constructing new rock rings for campfires or building fires against boulders or ledges is inappropriate as it blackens rocks and disturbs underlying soils. If you choose to have a fire where there are no existing fire rings, you must take the extra responsibility to learn and practice stringent Leave No Trace techniques, such as those outlined below.
