I’m cutting trees around 18″ plus at the base. 32 growth rings. I helped ‘re purpose an old house that was in the woods. One of the original settler log homes. Land was deeded by Andrew Jackson, south Arkansas. I have a log sill that is 9″ in diameter, 89 growth rings, maybe more. Both trees here are pine, 1/4 mile apart. Something must have been different back then.

This is a very basic guide to bunkers. Many areas such as bomb blast related pressure as it relates to entry door integrity really deserve much more coverage. And the section on construction techniques completely miss the point on culvert strength which is primarily related to earth arching and not the strength of the culvert material - look at the huge plastic highway culverts that are a few feet underground and support multi ton trucks. This book is a start but you need much more information to plan any kind of shelter.
Not to mention the “year without a summer” that happened after the eruption of Mt. Tambora in the Dutch East Indies in 1815. The resulting ash and smoke plume blocked the sun enough to lower the average temperatures only by a few degrees. It was enough to trigger famines in North America and Europe for several years until temperatures gradually normalized. If the Yellowstone caldera erupts the smoke and ash would block the sun much as would a nuclear winter and would trigger even worse famines and suffering from people trying to cope with minimum if any infrastructure for heat, water, medical, etc. just for the simple reason that we’ve got way more people now and more of us live in urban areas.
What research have you done on this? Are you simply making assumptions, because that's what it sounds like. The needs of someone trying to grow a couple tomatoes so the kids can see what they look like growing on the vine one summer are verrrrry different from the concerns of preppers who are thinking in terms of potentially supplying food for their family for many years.
Some lights are crank powered like our emergency radio above and having at least one of those is not a bad idea. Alternate light sources are candles, which are cheap but present a fire hazard, or chemlights, which are completely safe and heatless, but also have utility for marking, safety and signaling. Redundancy is a good idea, but emphasize flashlights and headlamps. Both require…
Grains. Grains are good for making flour or meal. Wheat and corn are the most common. Bear in mind that you will need a grain mill to process these, and I recommend a good hand mill in case power is an issue. By storing whole grains instead of flour or meal you drastically increase storage life. Again you can buy these in ore-sealed buckets, or repackage bulk purchases yourself to save money. If you want to increase the shelf life even more, you can turn them into flour and then into Hardtacks.

I personally like 5 gallon buckets with the gamma lids, so that I can access and rotate my food. I built shelves for food storage but I do have some of big Home Depot style orange shelves and they would work well. I also have some mix of number 10 cans but i like them less because they seem so bulky. For things that i rotate through slower input a Mylar bag in the bucket to keep thing fresh. I live in Utah and we have an industrial container store that sells buckets and lids for a great price, a lot less than the e-prep stores.

When you find out your buddy or mentor has months and months worth of food, water, medical supplies, tools, weapons and more it is easy to get discouraged before you even begin. This is a mistake. No matter where you are and how much or little you have to work with you can take steps right now, today, to improve your situation over the masses who don’t care or cannot be bothered to do the same.
When I got into bed that night, I noticed I was feeling a little off. Though I’d technically consumed enough calories, my stomach was still gnawing with hunger, and when I woke up the next morning, I felt energyless. I phoned Dr. Lisa Young, a New York–based nutritionist and adjunct professor at NYU, with a question: Is it really possible to live off freeze-dried food?
Also, what about a bike – perhaps with a electric generator that can couple to it, with a nice rack on the front or back to carry things in it? I really appreciate preparing and actually stepping into a lifestyle more reliant on my own skills and power, rather then something like a diesel generator that would be useless in the event of total system failure.
I think most phones get emergency alerts like that for their area codes. I get general warnings and Code Pinks (abducted children) sometimes. But the apps I recommend are both broader and more specific. For example, with Disaster Alert, I not only get tornado and flood warnings in my area, I also get notifications for any severe weather headed towards me and things like medical alerts for flu and whatever.
Legacy Foods 120 Serving Breakfast, Lunch, and Dinner Bucket is a great option for vegetarians or people who want more of a bland foundation that you mix with other ingredients. For $299, one bucket covers two people for two weeks at 1,500 calories per day. Although other companies drop the calories to cut costs, Legacy assumed you would add more ingredients to their base, so we thought the relatively low calories per day was acceptable.
After 15 minutes, I was startled to discover that the cereal had puffed up into a Kashi-like multitude of grains, flecked with tiny pieces of apple, complete with green peel, that looked just-chopped. It didn’t taste as good as it appeared: Eyeballing a fourth of the bag had resulted in a poor distribution of seasoning, yielding a flavor I can only describe as water laced with traces of cinnamon and sugar, though subsequent attempts tasted better.
