Was doing a litter sweep when I was a scout of our local crag and found a box on unused tampax spread all over the area. Fun to clean up that 

when on MOD land you always find kit that some one leaves behind after crash outs and stuff have picked up a lot of kit this way.
Partly destroyed Honda moped.
I've also transported an abandoned cottage-tent, complete with smelly mattresses, blankets, clothing, a baby cot, etc from Glen Etive... made even more distasteful with the knowledge that the anti-camping National Trust Warden had driven past it twice a day since it had been left there. To be fair to him though, I never once saw him out of his Land-Rover on any other occasion.
Also in Glen Etive, years later, I had the disconcerting task of opening a collapsed tent to see if anyone was inside it. There was a sleeping bag, rucksac, clothing, stove and rotting food, etc, but thankfully no body. I got a phone call from Lochaber Moutain Rescue a week later to tell me they had traced the owner, who had no intention of ever encountering Scotland's most ferocious predator again. He had been Midgied!
I once found a cache of army rations in Torridon and took as much of the good stuff as I could carry in a webbing harness-thingy with pockets. 2 lads turned up at my camp and we stuffed our faces at the fire that night. In the morning, one of them, after spotting the webbing, told me that it was only a certain regiment that was issued with that particular kit. Needless to say we hid the evidence as quickly as we could and went our separate ways in something of a hurry!
A mammoth tooth, unfortunately when it defrosted it turned into a dog turd.
