Hidden Food Caches

Hidden Food Caches

A cache is a hidden supply of food, water, tools, or other essentials stored separately from your main living area. Caches serve three critical survival functions: they provide backup supplies if your main stores are raided or destroyed, they support evacuation routes with pre-positioned resources, and they distribute risk so that no single loss is catastrophic.

The principle is simple: do not put all your eggs in one basket. In practice, building effective caches requires careful attention to waterproofing, concealment, pest prevention, and retrieval planning.

Cache Construction

Buried Caches

Burying supplies is the most secure concealment method. A properly buried cache is virtually undetectable without metal detectors or excavation.

Step-by-step burial cache:

1. Select the container — waterproof is non-negotiable

   • Best: 5-gallon plastic buckets with screw-top gamma seal lids. Watertight, rodent-proof, available everywhere pre-collapse
   • Good: PVC pipe (10-15cm diameter) with glued end caps. Cut to length, load supplies, glue the second cap. Completely waterproof
   • Good: Ammunition cans with intact rubber gaskets. Waterproof, crush-proof, compact
   • Acceptable: Plastic trash bags, doubled and tied. Cheap and available but vulnerable to puncture and rodents
   • Poor: Metal cans (they rust), cardboard (absorbs moisture), glass (fragile)

2. Prepare the contents

   • Wrap everything in additional plastic bags even inside a waterproof container. Redundancy
   • Include desiccant packets (silica gel) or a small bag of rice to absorb residual moisture
   • Pack tightly to minimize air space
   • Include an inventory list inside the cache so you know exactly what is there without unpacking everything

3. Dig the hole

   • Minimum depth: 45cm below surface. Deeper is better — 60-90cm is ideal
   • Dig down, not out. A deep narrow hole disturbs less surface area than a shallow wide one
   • Save the sod — carefully cut the top 10cm of turf/ground cover as an intact piece. Set it aside on a tarp or plastic sheet
   • Pile excavated dirt on a tarp, not directly on the ground. You need to remove ALL excess dirt that does not go back in the hole

4. Place the container

   • Set it in the hole. Pack dirt around it firmly
   • Backfill in layers, tamping each 10cm layer
   • Replace the sod cap exactly as it was
   • Scatter leaves, twigs, and natural debris to match the surrounding area
   • Remove all excess dirt — carry it away in bags and scatter it at least 100m from the cache site. Freshly turned earth is obvious to experienced trackers

5. Mark the location

   • Do NOT mark the cache with anything visible at the site. No stakes, no cairns, no paint marks. These scream “something is buried here”
   • Use distance and bearing from permanent landmarks: “12 paces due east from the large split oak, 3 paces north of the boulder.”
   • Record this information in a coded or memorized system. A written record can be found; a memorized one cannot
   • Take a photo from a specific angle if you have a camera. The photo serves as a visual reference without marking the ground

Above-Ground Caches

Sometimes burial is impractical (rocky ground, high water table, frozen soil).

• Tree caches — hang a sealed container in a tree, 4-5m up, using a rope thrown over a branch. Camouflage with bark and branches. Bears use this principle in reverse (they climb), so use a branch too thin to support an animal’s weight
• Rock crevice caches — natural rock formations with gaps and overhangs. Seal the container against moisture and wedge it deep into a crevice, then stack rocks to conceal the opening
• Ruin caches — in abandoned buildings, hide caches behind false walls, under floorboards, inside walls, or in spaces that appear structural (inside old chimneys, behind plumbing access panels). The more a hiding spot looks like boring infrastructure, the less likely it is to be searched

Building Integration

In your own structure, build permanent hidden storage.

• False floors — raise a section of floor 15-20cm on a frame. Cover with matching flooring. The space beneath holds flat containers
• Wall cavities — between studs in framed walls, there is typically 10-15cm of space. A section of removable drywall or paneling provides access
• Under stairs — the triangular space under a staircase is often wasted. Build a concealed panel
• Inside furniture — a heavy bench or cabinet with a false bottom. Items stored inside the furniture move with you if you relocate

Waterproofing and Preservation

Moisture Is the Enemy

Moisture causes mold, rust, rot, and spoilage. It is the primary reason caches fail.

• Double-bag everything — two layers of sealed plastic between your supplies and the world
• Desiccants — silica gel packets (scavenge from electronics packaging, shoe boxes, medicine bottles). Place one packet per liter of container volume. Alternatively, baked rice (dry in an oven or over fire for 1 hour) absorbs moisture well
• Vacuum sealing — if you have a vacuum sealer, use it. Vacuum-sealed food lasts 3-5 times longer than conventionally stored food
• Wax sealing — dip container seams in melted beeswax or paraffin for additional waterproofing

Pest Prevention

• Rodents — can chew through plastic bags, cardboard, and thin plastic containers. Use hard containers (metal, thick plastic) or bury deep enough that burrowing is unlikely
• Insects — bay leaves repel many stored-product insects. Place 2-3 bay leaves per container. Diatomaceous earth sprinkled around the cache exterior deters crawling insects
• Scent masking — food has odor even through plastic. Mask it by rubbing the exterior of the container with strong-smelling natural materials: pine resin, cedar shavings, crushed garlic. Animals rely on scent to find food; eliminating the scent trail eliminates the search cue

What to Cache

Food priorities (by shelf life):

Item	Shelf Life in Cache	Notes
White rice	10-30 years (sealed, dry)	The king of cache food. Dense calories, stores indefinitely
Dried beans/lentils	10-30 years (sealed, dry)	Complete protein with rice
Salt	Indefinite	Preservative, essential mineral
Sugar/honey	Indefinite (honey); 10+ years (sugar)	Calorie-dense, morale boost
Dried pasta	5-10 years (sealed, dry)	Quick-cooking, calorie-dense
Canned goods	3-5 years (longer if intact)	Heavy but ready-to-eat
Cooking oil	1-2 years	Calorie-dense but goes rancid
Spices	2-5 years	Negligible calories but enormous morale value

Non-food cache items:

• Fire-starting supplies (lighter, ferrocerium rod, waterproof matches, tinder)
• Water purification tablets or filter
• Basic first aid kit
• Fixed-blade knife
• Cordage (paracord, 50m minimum)
• Compact shelter (tarp, emergency blanket)
• Local area map

Cache Network Strategy

How Many Caches?

Minimum 3 caches for a solo individual or family:

1. Primary backup cache — within 500m of your main location. Contains 2 weeks of food and essential supplies. This is your “the house burned down” cache
2. Route cache — positioned along your primary evacuation route, ideally at the halfway point or a natural rest stop. Contains 3-5 days of food, water, and travel supplies
3. Distant cache — at or near your secondary location or rally point. Contains enough to restart: 2 weeks of food, tools, seeds, medical supplies

Location Selection

• Away from water — not in flood zones, not where the water table rises seasonally
• Away from trails — off the path of normal travel. If you walk past your cache site frequently, you create a trail that others may follow
• Near landmarks — you must be able to find the cache under stress, at night, possibly injured. Use unmistakable landmarks (large rocks, distinctive trees, stream junctions) not small, movable markers
• Avoid metal detector zones — if your cache container is metal (ammo can, metal bucket), bury it near other metal (old fencing, abandoned equipment) to mask its signature

Inventory and Rotation

• Check every cache every 3-6 months. Open the container, inspect for moisture intrusion, pest damage, or container degradation
• Rotate food — eat the oldest cached food and replace with fresh stores. This keeps your cache stock within its shelf life and confirms the food is still good
• Update the inventory list each time you access a cache
• Vary your approach route — do not create a worn path to your cache site. Approach from different directions each visit

Retrieval Under Pressure

You may need to access a cache while being pursued, in darkness, or while injured.

• Practice retrieval — visit each cache in daylight, then practice finding it at night using only landmarks and pacing
• Time yourself — know how long it takes to dig up and repack each cache. You may not have time to dig for 20 minutes
• Shallow “grab caches” — small caches buried only 15-20cm deep that can be scraped out in seconds. These contain minimal supplies (fire kit, knife, 2 days food) for true emergencies
• Never access a cache while being observed. If you suspect surveillance, abort and return another time. A compromised cache is worse than no cache — it draws attention to your planning and supply network
