I think that is awesome, I do bring some type of small archaic rake with me to blend things but honestly don't think its quite like what you are doing.

Your something to live up to, I appreciate your efforts and will start paying attention further.

I usually don't camp in designated spots so I don't know if this has anything to do with it. My spots are small and usually not something one would stumble onto on a normal camp/hike expedition. That being said and the worlds population expanding, I think you are the more model camper.

I used to think everyone did that, but as time goes by I'm learning that some people are just sloppy backcountry housekeepers.

I don't add anything that wasn't there before I camped there. but I cut my fire ring from a soddy place with my camp shovel and it fits back on top like a lid after I drowned my coals well and good and put the dirt removed from the hole back on top of the wet ashes. I have never left trash behind me. I reake the leaf litter from the area I will place mt tent and I rake it back into place when I break camp.So once the fire pit is taken care of there is little sign I was there.
I would say howevere that if I was in a survival situation , you know became logistically misplaced(Marines don't get lost LOL) ;and it was an area that was used by plenty of peaope each year I think if I made a survival shelter I might leave it standing for some other that might come later and not know how to build one. I am not positive I would do that as it has never happened I just think about contigencies.

I rarely camp anywhere that doesn't have established sites. And I rarely-to-never create a new fire ring. I do try to leave the site in better shape than I found it. However, if I were to create a site and/or fire ring I would use the same basic rules as Adam.
