It wouldn't be so bad if people at least used septic TP so it breaks down faster, as much as it rains it would help. Its not hard to find a big rock away from the campsites, upturn it and then do you business inside, then put it back. I know the forest service isn't rolling in dough, but some of the busier lakes need some kind of a composting toilet. With as many people going up there, you need to either issue permits and have them go thru a quick pamphlet on wilderness etiquette or just find practical solutions to the problems. Personally, I hate it more when cows crap everywhere and by the water. I'm always hoping the wolves and bears will be enough of an issue they go graze elsewhere.
Cairns, if done right is a good thing, as most people are just there to hike for the day. Beats having the SAR people constantly up there. Just a matter of fact that most people have no clue. I constantly see people under dressed, or totally clueless about. if you want a wilderness experience you just have to get away from the more popular paths.
If anything, I think it would be fun to pick some off the wall lakes that have very little info on them and scout them out. Lots of area up there off the beaten track. I would love to find some nice lakes full of big, tasty trout that gets little pressure. I seriously need to make friends with the rangers and get some good tips.
