(I'm tickled to post this in the "Random Crap" category, by the way.) Also, this is not a critique of how anyone reading actually uses an outhouse--seriously, you pretty much have to work in The Industry to know this stuff.
Ulalani, who just delurked (yay!) wrote a post about a hike she recently took, and she was...well...disappointed in the outhouse at the trailhead. You see, it had been billed as a high-tech unit, and due to the odor (and maybe some other stuff) she felt it was misrepresented.
I may have mentioned before, I know a thing or two about outhouses. I spent four years of my career managing recreation sites for the Forest Service, and cleaned between six and ten outhouses a week during that time. Yeah, come rain, snow, freezing rain and snow, sleet, zillion degree temperatures, dust storms, you name it, I cleaned the Vertical Government Shitbox. It was interesting.
Now, I look at the outhouse Ulalani pictures and I think, "That's a pretty nice unit, there. Looks like a two-room Sweet Smelling Toilet (SST) with a nice concrete paneling made to look like wood, but a whole lot more fireproof. Probably made by RomTec out of Oregon. Yeah, that's a pretty nice shitter." But it was stinky. Well you know, it didn't have to be stinky. You can put a whole lot of dookie in one of those (I believe somewhere in the neighborhood of 500 gallons) and it won't stink. Unless! Unless! The very specific shitbox technology is defeated...by the user. Yes, it is the user of the outhouse who makes it a stinker, and not with what they do inside the hole.
You see, the outhouses these days are designed to vent the stink out through the big black pipe on the outside. Did you know it is black for a reason? Why yes, yes it is. It is black because it will heat up, the heat then draws the air from inside the concrete poo vault up and out, high enough off the ground that it shouldn't waft down to the smeller. (Of course, sometimes prevailing weather conditions like wind and inversions can defeat you.) Also, the unit should be oriented so that the black pipe faces south and/or east, so that it receives as much radiant heat throughout the day.
Next, (and this is the very most critical part) the air must be kept from wafting up into the room through the toilet riser. That means the lid must always be closed when the throne is not being used for its primary purpose. And the door must also be closed. Not only does this keep the stink down, it keeps the flies from getting in the room, and from getting in the poo. And boy howdy, you don't want flies in the poo. Not only do they fly up and tickle your butt when you're seated...but they draw in spiders. Yes, nothing like opening the lid of the toity and seeing big cobwebs strung around. Clenches me right up.
So, to recap:
1) Toilet lid closed
2) Door closed
Finally, based on my professional experience, just walk up the trail a tick and potty in the woods. Don't dookie--that's not savory for anyone, but piddles are totally okay. Frankly, I'd walk a long way into the woods to piddle, rather than hoisting my lady bits over some open hole. Outhouses...brrr. But if you gotta, you gotta.
There's your lesson. Don't say I never taught you anything. And have I mentioned how grateful I am to not have to clean outhouses nowadays?
