Any best practices for holes in the ground? I can imagine that metal detectors and various animals change the threat model, but I suspect there are also unknown unknowns at play here.
- LinuxBender 4y agounknowns at play here This sounds like a fun thought exercise. No idea who we are protecting against but some factors might be: - Moisture. The containers need to be completely sealed from moisture and have resistance to acid from the soil. - Metal detector. Perhaps this could be mitigated using a skid-steer with an auger drill attachment? Some of the larger skid-steers can use an 80 inch bit. Excavators can use even larger bits and drill at angles to get under solid objects. Rock auger bits can get through some rocks. Layers of gravel might obscure detection from ground penetrating radar. - Location should be obfuscated by trees to avoid satellite and aircraft imaging from Keyhole/Google/Others. - Accessibility. If there is a few feed of rocks above the container and a rope passes through the rocks, then retrieval is less likely to damage the container and one would not need dig as deep for extraction. - Drill numerous holes and find some other use for them whilst singing One of these things is not like the other
- jstarfish 4y agoRe: moisture, you also need to account for condensation forming inside the box as your seal fails. For anti-metal detection, ideal spot would be atop/near a buried junkyard. Once they've gone to the trouble of excavating a rusted Dodge Neon, interlopers are not inclined to dig there again.

Stuff your cash/jewels/drugs + desiccant and use PVC sealant caps with waterproof sealant. Bury as deep as you want. I would expect that to last decades. Plus it should not set off any metal detectors.
- andrewinardeer 4y agoWhy wouldn't the jewellery set off thr metal detectors?
- 988747 4y agoJewels, as in diamonds are non-metalic. gold is different beast
- MerelyMortal 4y agoHopefully diamonds will be like gold in that Twilight Zone episode. Diamonds were worthless until De Beers paid a marketing agency to make the public think they are valuable.
- coffeebeqn 4y agoThe loss of value when you as a private citizen sell diamonds is going to hurt a lot compared to gold where you only lose a few percentages to premium spread. With shady diamonds you probably lose 80-90% of the value when you attempt to sell them. If I was hiding wealth it would definitely be gold. Maybe just do multiple sites geographically dispersed so if you lose one it’s not such a big deal

- 0cf8612b2e1e 4y agoI was speaking towards the method itself is not vulnerable to metal detectors. If you load it up with metal bars, that’s on you.
- Scoundreller 4y agoI think metal detectors can only tell the strength of the magnetic pull, which means they can't differentiate between a shallow piece of small metal or a large piece of deep metal. In other words, salt the surrounding area with lightly buried worthless coins, nuts, bolts or metal scraps and anyone trying to find your loot will give up. Ground-penetrating radar is a different beast, but also has its limitations: https://en.wikipedia.org/wiki/Ground-penetrating_radar#Limitations https://en.wikipedia.org/wiki/Ground-penetrating_radar#Limit...
- gopher_space 4y agoYou might look at improving or expanding your drainage. You'll learn something useful and look less suspicious. In my mind the threat model is whatever cost/benefit analysis the people searching have in their heads masked by the unknowns you mention. People can just dig up your yard, if you see what I mean.
- Scoundreller 4y agoThere's some joke about an alleged terrorist being in prison, so he sends a "coded" message to his wife about there being something buried in the backyard. The message is intended to be intercepted, and it is. The investigators tear apart the backyard and find nothing. The alleged terrorist then lets his wife know the backyard is prep'd for this year's potato planting.
