1925 North Dakota license plate and a 1922 North Dakota license plate are probably the neatest things.
Also found a cedar arrow shaft with an old odsidian broadhead 8" below the bark to the end of the broken arrow piece. A home spun 2 or 3# sledge head you could still see the lathe marks in the rust the threaded handle was busted off. Elk horn tips about 5 foot up an old fir about 3" below bark. Found a bandsaw blade I think about 8" from the tip of the teeth to the back of the blade, Found it on the up hill cut while face cuttin a 28" alder. Also found a 20hardnose bar and chain in an old maple she was healed just enough so you couldn't see it any more with out looking very very close found that in an up hill cut also. Then just all the other stuff like rail spikes, fence, staples, bullets, nails, bird nests and that type stuff.
