Neat discussion idea!
I'm all for the idea of underground bunker-built or earth berm homes.
They maintain a fairly constant temp rating depending on the construction and insulation factor (depth of soil) but there are design drawbacks and
issues that need to be addressed in the building of such a structure (at least to code that is) and many factors that can impede on having a livable
If you are just planning on digging a 30' deep hole in your backyard and tossing in some old metal shipping containers for a save haven, then by all
means, but I have to ask.. why in the world you would need something buried that deep unless it was to be used for nuclear / fallout protection? Dirt
weighs alot, and at that depth you may have to address groundwater and seepage issues depending on your natural area. If it were me, I could just go
find a cave. Yeah, alot of people may know the location, but there is usually only one way in or out. Plenty fine if you can set up a good warning
Caves are naturally ventilated, and extremely sturdy from centuries of erosion and weathering. If you have to chose one, make darn sure it is not
prone to flooding. Some deep limestone caves are known for this, one torrential downpour and you could find yourself in snips creek. Quite literally.
Also.. make sure if you are going to go exploring around in one, take a buddy or four and plenty of backup lights. Spelunking is a pretty extreme
sport, kinda like rockclimbing at night. I spent a few long years doing both in my area, and after some reeeeaaally scary experiences... well,
needless to say I don't do it anymore.
Some caverns have their own source of freshwater aquifer, but alot of them are protected areas. Bat havens, protected habitats... gated... you name
it. But in times of strife, all of these things said, well they could be to your benefit.
Since I'm cheap and can't go to the lengths of finding an atlas II silo in my price range and area... I would take a cave any day. Maybe it is
just my primal self.
