The established ring in the picture was full of trash when we arrived and almost overflowing with ash and charcoal. In our case it was the site’s view, not the fire ring, that attracted us to the camp site. Everyone cooked on a fossil fuel stove, of one type or another, but the camp fire was still lit for ambiance. It was a bigger fire than needed, because the fire ring was big. Sad to say we left the campfire much the way we found it, plus a bit more ash and charcoal. The excuse was that there was no way we could have made any real impact on the fire rings contents and we did not think we were responsible for cleaning it all up.
Based on that experience I believe, outside of a fire ban, backpackers will make a camp fire. Therefore I think I am in the camp (sorry) of small distributed camp fires. If I make the fire then I am responsible for making sure it is safe and can be easily cleaned up afterward to align with LNT principles.
I now take a twig stove with me for cooking, that I can convert into a fire ring big enough for a small group. I do not need to find and use stones for a fire ring, which make restoring the site easier.
