Cache Placement

Part of Food Storage Infrastructure

Cache placement is the strategic positioning of food stores to maximize security, access, preservation quality, and resilience against loss from any single event. A community that stores all its food in one location risks losing everything to fire, flood, theft, or pest infestation. Distributed caching — the same principle hunter-gatherers used for 200,000 years — provides redundancy that single-point storage cannot.

The fundamental insight is that all storage is probabilistic. Any single storage location has some probability of loss from each threat. Distributing food across multiple locations reduces the probability that any single threat will destroy the total supply. A fire that destroys one cache leaves others intact. A rodent infestation in one storage building does not contaminate a separate cache. This is not paranoia — it is basic risk management applied to the most critical resource.

Threat Analysis for Placement Decisions

Before deciding where to cache food, analyze the threats specific to your location:

Climate threats:

• Flood zones: identify which locations are above the 100-year flood line
• Landslide areas: steep slopes with shallow soil are high risk
• Wildfire corridors: dense forest uphill of a building creates high fire risk
• Wind damage: exposed hilltops vulnerable to storm damage

Human threats:

• High-visibility locations attract attention from strangers
• A single obvious storage building is an easy target
• Distributed, low-profile caches are harder to identify and access completely

Animal threats:

• Bears: identify where bears travel seasonally
• Large predators near livestock
• Ground squirrel colonies near grain fields

Infrastructure threats:

• Flood risk from dam failure upstream
• Proximity to roads (vehicle damage)

Primary, Secondary, and Emergency Caches

Three-tier caching system:

Primary cache (60-70% of total stores):

• Main storage facility with best environmental controls (temperature, humidity, pest exclusion)
• Most convenient access — within 100 m of main living/cooking area
• Organized inventory system; frequently accessed
• Example: main root cellar, grain barn, smoke house

Secondary cache (20-30% of stores):

• Secondary storage at different location from primary — at least 200 m away and separated by natural firebreak or physical barrier
• Contains long-life foods: preserved grain, salted meat, dried legumes
• Less frequently accessed; check monthly
• Example: secondary root cellar in a different field, grain pit, hillside cache

Emergency cache (5-10% of stores):

• Concealed, secure, unknown to all but core family/leadership
• Contains high-calorie, long-life foods: grain, dried legumes, salt, preserved fat
• Designed to sustain 2-4 people for 30-60 days
• Located in a different direction from primary and secondary caches
• Example: underground cache in a remote field corner, cave cache, buried container

Site Selection Criteria

For permanent storage buildings:

Elevation above flood: Use historical evidence (flood marks, old accounts, local knowledge) to determine maximum flood level. Site primary storage at least 1 m above this level. Losing all food stores to a flood is catastrophic; the inconvenience of a hillside walk is trivial by comparison.

Drainage: Water must drain away from foundations. A building at the low point of a slope collects water from all directions. Choose flat ground or upper slope positions where water sheds away.

Separation from living areas: Sufficient distance (30-50 m) to prevent fire from living quarters reaching storage, and vice versa. Historical farmsteads maintained this separation deliberately. The barn and granary were not adjacent to the house — fire risk was too great.

Access in all weather: The path to primary storage must be passable in deep snow, mud, and rain. Paved or graveled paths to storage buildings prevent mud closure in wet weather.

For hidden or underground caches:

Concealment: The cache entrance should not be visible from main travel paths. A depression covered with brush or a false stone wall provides concealment from casual observation.

Natural landmarks for relocation: Mark hidden caches with subtle, permanent landmarks — a specific rock formation, a distinctive tree, measured distances from a known point. Memory alone is insufficient; mark the location in a secure map.

Multiple approach routes: A hidden cache accessible by only one path becomes detectable when that path shows wear from repeated use. Plan at least two approach routes and alternate between them.

Drainage: Underground caches must have drainage. A buried cache that fills with water destroys its contents. A gravel drainage layer beneath the cache and an overflow channel to lower ground are essential.

Placement for Different Food Types

Root vegetables:

• Prefer underground or partially-submerged storage (stable temperature, natural humidity)
• Site cellars where drainage is excellent (high, well-drained soil)
• Locate near kitchen for convenience but with separate access from the main house

Grain:

• Grain pits in well-draining clay or chalk soil
• Above-ground granary on raised floor (prevents ground moisture and rodent entry from below)
• Separate from root vegetable storage (different temperature and humidity requirements)

Dried and smoked meat:

• Smokehouse with good ventilation for initial processing and short-term storage
• Cool, dry conditions for longer storage — not humid root cellars
• Elevated storage preferred (hooks, hanging rods) to maximize air circulation

Preserved liquids (vinegar, wine, cider, ferments):

• Temperature stability is critical — buried or deeply insulated storage prevents freezing and excess heat
• Ceramic crocks are heavy; locate storage close to point of use

Dispersal Patterns

Linear dispersal (for narrow valleys or coastal settlements): Space caches along the settlement’s length, separated by at least 200 m. A single destructive event (flood, fire) typically affects a limited linear distance.

Radial dispersal (for open terrain): Place primary cache at the center of activity; secondary and emergency caches at cardinal or intercardinal directions at increasing distances. This pattern ensures that no single directional threat (approaching wildfire, flooding river) reaches all caches simultaneously.

Vertical dispersal (for mountainous terrain): Place emergency cache at higher elevation (above flood and wildfire lines), primary storage at mid-elevation (convenient access), and secondary storage at different aspect (north-facing for coolness, south-facing for dryness).

Documentation and Access Control

A cache placement strategy is only as good as the documentation:

Cache registry: Maintain a written record of each cache location:

• Location description (and map reference if maps are available)
• Contents and approximate quantity
• Date stocked and estimated consumption date
• Access method (key, combination, concealment method)

Access control:

• Primary cache: multiple household members know access; daily access expected
• Secondary cache: 2-3 trusted adults know location; accessed only when needed
• Emergency cache: 1-2 people know location and contents; never accessed except in genuine emergency

Knowledge transfer: Cache locations must be transmitted to the next generation or to successors. A cache whose location is known only to one person who dies is lost food. Document locations in a secure, permanent record.

Cache Rotation and Inspection

Distributed caches require a systematic inspection schedule to prevent unnoticed losses:

Cache Type	Inspection Frequency	Items to Check
Primary	Daily (passive) / Weekly (active)	Temperature, signs of pests, inventory levels
Secondary	Monthly	Condition of containers, any moisture or pest evidence, inventory
Emergency	Quarterly	Seal integrity, contents condition, access route clear

Discover and address problems early. A small rodent intrusion detected in a monthly inspection loses days of food. The same intrusion undiscovered for a season may destroy the entire secondary cache.

Strategic cache placement, maintained and documented, is what separates a resilient food supply from a vulnerable one. The marginal effort of maintaining multiple storage locations pays back in full at the moment of any single point failure.
