Disasters have, of course, put pressure on communities for a long time—including in the region now known as Mesa Verde, an area in southwestern Colorado renowned for its astonishing cliff dwellings. An estimated 25,000 to 30,000 people lived at Mesa Verde between 1225 and 1260, and then the population declined rapidly. For a long time, archaeologists had no idea what had become of them. But Pueblo tribes—in what is now New Mexico and Arizona—had, for generations, told stories about an exodus from Mesa Verde, and they claimed the previous inhabitants as their ancestors.
I would like to add, buying too much of something at one time. I have lots of water and food stored. Toothpaste, soap, qtips and such. How much medical and bandaid? NONE. Make a list most definitely. But include stuff you HAVEN’T BOUGHT yet. Checkmark items you have with the amounts. Also I have 3 non bullet weapons and have a 4th on the way. A regular size crossbow (with a broad head it will penetrate any class of body armor) A pistol crossbow which is actually more powerful than the large one, but you can’t get broad head for them. They will however penetrate 3/4 pressed plywood particle board. Good for human threat or rabbit get. A wrist rocket slingshot with “hunting” rubbers and I’m waiting on a new item called a “Pocket Shot”. It’s a new type of slingshot that self centers the ammo. You can fire almost twice the ammo in the same amount of time. All 4 will be valuable to be quiet during the first month. After the hordes have been thinned, noise from a gun will bring less attention.

The overall contents of your doomsday supply list will be based very much on what sort of shelter options are on the table, and how well-stocked with food and water such a safe house is. To get through that critical period of fleeing to a safe location, survivalists recommend keeping a "bug-out bag" on standby, with enough supplies to get you through the first 72 hours or so.

3. The water will slowly filter through the charcoal and drip out of the cap. Put a bandanna or another cloth over the hole to filter out any bits of charcoal. (If you’re experiencing intestinal distress—and you very well might be, since your body goes into different kinds of shock in these situations—eat a little bit of the charcoal. It’ll help bind you back up.)
It’s impossible to carry all the food you will need for a week unless you’re eating very high density proteins like nuts.  Nuts and dried meat are two of the easiest off-the-cuff meals.  Canned food has a lot of water that is wasted during the cooking process.  Stay away from heavily flavored or salted nuts.  The amount of salt present in the unsalted nut mixes is still sufficient enough to replace electrolytes.
