What a great place to explore..
By you pictures and description of the age of the site.
I would say that the tall single gabled part of the house is the 1817 original house.
The back of that part is usually where people would add on and it is the direction of the outhouse.
By the looks of the add-on I think the outhouse is under it.
They were usually about 30 feet or so from the back door.
That would be the reason you haven't found the outhouse.
Ok, that my idea on outhouses.
Now as to hunting in heavy trash.
About the best thing I can say is raise your reactivity, lower the sensitivity, go real slow and pull all of the targets Ferrous and non-ferrous.
Good luck..
