I can think of several places where I’ve seen poop
Dublin Lake on Tanner Butte – someone just pooped on the ground and made no effort to cover it. 10 feet from campsite. I dug a hole with a stick and buried it.
Near McNeil point on Mt Hood, 20 feet off the trail – same thing, but there wasn’t a lot of soil so it was difficult to dig a hole. They should have chosen a better spot with soil.
Those were just people that never got the message about digging a cathole. I think it would be difficult to get those people to do this properly, they’re just slobs. The best you can do is to at trailhead, have instructions on how to dig a cathole.
On PCT near Mt Adams – a small spot right next to trail. I dug a hole and there was already poop there so I moved over a bit, repeated several times. I should have chosen a better spot to camp – that was very small area and surrounded by downed logs so difficult to find a spot to dig a cathole.
Strawberry Point on the Olympic Peninsula. It’s a fairly small space with many many people using it. It was a mess of poop and TP.
There are some campsites or areas that are overused. My solution is to choose another spot. It’s pretty easy to figure out which areas are like this. The forest service could put up a sign saying this area is closed to recover from over use. Or identify areas on a map at the trailhead that are over-used and recommend people camp somewhere else.
Several times I dug a hole, encountered poop so moved over a bit. No big deal.
Many many times I see TP flowers but no poop. Maybe a rock placed on top so the flower doesn’t blow away. I think that’s just misinformed people, they think they’re warning people not to step on their poop. It’s really just aesthetic – humans don’t like to see it. Maybe you could put up a sign at trailhead with a picture of TP flowers in the wild, tell people this is aesthetically disgusting, just bury your poop in a LNT manner and the chance of anyone stepping on it is small. I think those people are actually trying to do the right thing, they just need to be educated.
If you regulate that people carry out their poop, the slobs will just ignore that like they ignore the current regulation. The people that leave TP flowers just need to quit doing that, no need to carry it out.
If it’s a heavily used constrained area, like a climbing route up a mountain or along the Colorado River, then yeah, those areas should require that you pack it out. Or they should have pit toilets. The pit toilet at Camp Muir on Mt Rainier for example.
It’s complicated. One solution, forest wide pack out poop regulation, isn’t good. Do case by case basis solutions.
