Emergency Kits, Shelter, Nav, Signals etc

UPDATED 6/2/17

Be Prepared is the long – time Boy Scouts motto. A little pre-planning, some training and then lots of practice and you are off to a good start.  “If it’s sun, its fun.  If it’s raining, it’s training” Assemble some simple gear and know how to use it!

So what might be in a pocket emergency kit. Something small that you will be inclined to carry either in your POV or preferably on your person while out in the boonies. Any kit should be tailored to your likely locale and situation. Here’s a photo of one of mine, starting with the carrying pouch that can clip to a belt. It is a standard US Military M1967 Compass pouch, or when rigged upside down on the ALICE clip, is an emergency field dressing pouch. Either way, just the right size for a very basic kit. Note: Don’t try to fly “commercial” anywhere with some of this stuff! Procure local replacements upon arrival.

Inside it is a standard “drug store” soap dish wrapped with electrical tape. You could just carry the soap dish in a shirt pocket to save the bulk (and therefore more likely to carry it). Wrapped in electrical tape around the edges, it is pretty water/immersion proof. That tape can come in handy as well – be generous.

So what’s inside? Some real basic stuff as you can see below.

This one contains the box itself (collect water), 3 feet of electrical tape, miniature “aim-able” signal mirror, bandages, antiseptic towlette, zip-lock bag with pain killers, heavy-gauge aluminum foil (collecting/heating water etc), miniature butane lighter, magnesium fire-starter block with hack saw blade scraper, longer hack saw blade (“Master Key”), fishing hooks, lure, flies, light and heavy fish line, sinkers, single edged razor blade, snare/repair wire, P-38, compass, “keychain” LED Flashlite (to read / charge compass phosphor at night). My priority if I could only take two items: The signal mirror and the magnesium fire-starter block with hacksaw blade scraper.
Use that magnesium block to get that fire started;  on deep snow, build it on a “log raft”. It will be long gone in the morning, but it warms up the chow hall and coffee in the meantime.

So who’s idea was this, anyway.

Below: On a larger scale is another kit you might keep with your POV, mountain bike, dirt bike, canoe, kayak or clipped to your utility belt along with that multi-tool and canteen. Sized for cross-country day hiking / skiing or just getting stranded in some remote place. This one is packed in a US Military M1956 ammunition magazine pouch; of course any suitable pouch will work – but these are indestructable. Below:

Contents shown here:

A bit more stuff with some “luxury items”. A 36″ square International Orange “Panel, Marker, Survival, Aviation” NSN 8345-00-140-4232, a 3″X5″ aim-able signal mirror, plastic “survival cards” containing info on signaling, food and water procurement, first aid, shelter building, navigation etc (you DO know all this stuff BEFORE you head off to the bush don’t you?), combination whistle, compass and waterproof match container (with strike-anywhere matches), indigenous paper currency as appropriate to your likely AO, small green Chemlight, foil packets of tea, coffee, chicken bullion, hard candy, fishing hooks, lure, 25′ of 50 pound test fish line, stainless steel pocket knife, magnesium fire-starting block, hack saw blade, wire saw, pain killer meds, small nails, miniature butane lighter and backup compass. Note: Food (or bulky means to obtain it) really has no place in an emergency kit – you can live for 3 weeks without eating, but it has a big psychological value.

The small round object in the lower left corner is a spool with 50 feet of # 34 gauge wire for the antenna of the miniature crystal radio receiver inside it (no batteries required). That consists of a torroidal inductor in a fixed tuned circuit driving a crystal diode and high impedance earplug. This is a morale-sustainment device so you can listen to the local news, the Big Game or Golden Oldies while-U-wait. It is broadband tuned, of course depending upon local signal strength.

Lost? Again?

Field Expedient Radio Direction Finding

Speaking of radios, if you have a simple “transistor AM radio” you have a great navigation tool. A field-expedient Radio Direction Finder. The ferrite loopstick antenna in these things has a distinct “figure 8″ antenna reception pattern. You know, you have to rotate the radio around to find the position needed to hear that AM station the strongest. The “nulls” in that pattern are what you want – where the signal is the weakest – the null bearings are very sharp and are found off the ends of the radio. (The signals are received the strongest when the target transmitter is broadside to the radio). Upon rotating the radio about a vertical axis, the signal will drop sharply when the long axis of the radio is pointed either towards or away from the transmitter. If you know the station’s antenna location and frequency, you are in business; you have a Line of Position (LOP); you are somewhere on that line. It takes 3 or more LOP’s to resolve the 180 degree ambiguity and to develop a “navigational fix” – and there you are (more or less).

I carry an aviation sectional map of the areas I may be in. They have all kinds of useful information as well as the exact location of most AM radio stations’ ANTENNAS , their frequency and callsign. (A generic map will also work  – just less precise as to transmitter location!  Resulting accuracy all depends upon how far away it is from you.) On the above photo I had taken LOP’s from KNBR, KCBS and KRAK (it was located in Sacramento at the time). When the signal “nulls”, sight along the long axis of the radio to a distant object in exactly that direction then use your compass to determine the objects’ azimuth; then plot it on the map – in BOTH directions to/from the station..

If you’ve already oriented the map (true north) with your compass you can just use the radio edge as a ruler to plot the LOP as I have shown here pointing to/from KCBS. The 3 LOP’s converged. Ideally to a point but usually a triangle, sometimes a large one. I was in the “East Bay Hills” and I was inside that triangle. It works! Quite well. Try it! This technique was a staple in the 20th century for aircraft and vessel navigation.

(When using a radio and a compass in the field be aware that the speaker magnet in the radio will have a strong local effect on the compass!)

If you are lost (say, at sea off California) and you tune in KCBS on 740 KHz (they will announce their call sign/location) you can just follow the null bearing in. You know you are somewhere West of California (I hope you know at least that!) so that fact – the sun rises in the east if you’re really confused – resolves the 180 degree bearing ambiguity. Got it? Steer a course towards KCBS, keeping its signal in the Null.

Forgot your tent? Bleeding? Remember The Rule of Three’s to prioritize your efforts: You can live 3 weeks without food, 3 days without water, 3 hours without shelter (severe environment), 3 minutes without air and 3 seconds without blood. So build a hootch long before you start stalking that Holstein for a steak dinner….And ALWAYS work on your signalling! (assuming you WANT to be located – if you don’t, work on your camouflaging).


Your House of Sticks, ready for the thatch covering.

Snow Cave next to rock. Donner Summit Feb 1978

Above: Sometimes you can just enlarge an existing space near a tree base or large rock – saves some work. But colder than a regular snow cave. Donner Summit CA during a Navy cold-weather training exercise, MIUW 1920; circa 1978.  Mike and I were the residents and a single candle lit the place up quite well and warmed it a bit too.  Don’t forget a vent punched halfway up the wall with a ski-pole.

I had left my snow shoes outside overnight – and a heavy snow followed and the wind knocked then over.  I couldn’t find them in the morning – had to hump my gear out using my LPC’s – (Leather Personnel Carriers).  The local ski resort guys found the snow shoes the following spring, called me, and I got them back.  (I had left the ski resort bartender a description and my phone number) Nice!

Good lesson-learned.

Or, yer basic hasty-hootch with built-in Mountain Fir Air Freshener!(Don’t cut green branches during training – I found this one when I arrived here. I had a room in the Green Tarp Motel in the background. Honest!)

Pretty comfy and dry inside and you can add an insulated floor as well.

Snow Cave & Breakfast Buffet

It’s convenient if you dig your snow cave just a short walk from the Breakfast Buffet line / Comm Center. Teach your kids some field-craft. They’ll just remember it as an adventure.
For now…….

Cold Weather Training, Mt. Rose Nevada, USN

Or just throw a tarp over your snow trench. Training with MIUW 1920, Mt Rose Nevada.  Shadows getting long….February 1977


Basic beach bungalo with fresh crab for lunch!

Snow Cave Double-Ender

Digging a “double ended” snow cave to accommodate 5 guys – makes for easier access. Don’t get your clothes all sweaty while doing this – you’ll regret it later.  Next time, get a bigger shovel!  An E-Tool is a lousy snow mover. LOL!

Snow Trench Hootch

If you are lazy or just in a hurry, a snow trench makes a decent hootch. This is the Deluxe Model with a branch for a ridge pole to drape your poncho over. Align it cross-wise to the wind if possible.  Stick a ski in the snow at each end so your buddies can find you in the morning after that overnight snowfall !  You don’t want to be late for chow…


Or your basic beach cliff cave – very cozy, room for a few friends plus a nice driftwood fire.

Plus a nice beach view to go along with it. Make sure you know when High Tide arrives !!

Then there is the standard US Army “Shelter Half”, 2-man pup tent. Each guy carries half of the parts to make a complete tent as seen below. Heavy, but reasonably good like most military field gear under the circumstances…

Or, you can rig it between two trees:

Shelter-Half tents in the Snow MIUW 1920 Training

Above: The standard issue “Shelter Half” tent works well to block the wind. Buddy-up and set up into the tree line. US Navy cold weather training, Mt Rose, Nevada.  January 1979.

Shelter Half tent on wood frame for displays

Shelter Half tent on wood frame for displays

Above: The same type of shelter half tent, here rigged on a wood frame for indoor display purposes. (no stakes hammered into the floor).. Two 8′ 2×2, two 82″ furring strips, a couple of 5/16 bolts with wingnuts, 2 conduit clips and some screw eyes at the ends for attachment. I added the line tensioners to ease setup (anywhere) but to also reduce the display space needed in a display. Sprinkle some field gear around, instant vignette.

With those wood supports it would be pretty uncomfortable to sleep in – but it works great for indoor displays like this. Veterans Day.

Igloo spiral construction

Igloos are a basic, well proven shelter from wind and cold. Learn the spiral construction used by the Eskimos.  It’s all in the shaping of the interlocking blocks.  Near Strawberry CA in the Sierras with the “Young Marines” youth group.

Hasty Lean To Shelter USMC MWTC

A Hasty Lean-To shelter. Quick, simple effective. Cover with pine boughs, insulate the floor, build heat reflector out of logs/branches; get a fire going between them. This one was a Model Home open house at the USMC Mountain Warfare Training Center.  Here trying to figure out which room the PRC-47 goes into.

So there you are: Bleeding has stopped, headache gone; everything is set, you are comfy in your Hootch and you know which direction the Safe House is. (125 degrees magnetic: directly below the star Antares 2 hours after sunset, directly below Spica 5 hours after sunset and directly below Regulus 2.5 hours before sunrise). Day signals set out, signal fire going, fresh catfish on the spit, hearing about the big traffic jam on the Interstate with your crystal radio. (And you just heard on the local AM radio station that the Sheriff has just called off the search for Joe Bozo who has been missing in the mountains for the last month.)

However, you need some clean water to drink (a high priority). Maybe even make some tea, coffee or chicken soup as a morale builder. No container? Just look for the omnipresent plastic bottle, available everywhere. After you get your fire started, fill the bottle to the TOP with local, filtered water (you DO know how to make a water filter…), set close to the fire and let the radiated heat BOIL the water to sterilize it.

HowZat? Water boils at 212 degrees F at sea level, (lower temps at-altitude). But most plastic bottles are made of “PETE”, (recycling code “1”) and PETE melts at 482 degrees F. The water can’t get hotter than 212 degrees F so neither can the plastic that is in contact with the water. So the water keeps it “cool” and the bottle doesn’t melt or burn – but the water will boil as radiant heat passes through the plastic.
HA! You say… It works, see below. I once found an empty half-gallon plastic Tequila Mixer bottle and had a nice hot “shower” at a Yuba River campsite with this technique.


Water happily boiling away in a plastic bottle next to the fire.

Pine Needle Tea

If you brought your canteen cup along, make some Pine Needle Tea.  If not, you could also boil and brew some tea in that plastic bottle.

Field Expedient Beer Cooler

Or, maybe you will get lucky and find someone’s forgotten cache in their Field Expedient Beer Cooler
—————————————————————————
Here’s an example of a guy who paid attention in SERE school (Survival Evasion Resistance and Escape).  He was not happy that we found his survival cache….Notice that he got the sun angles and shadows just right. Good job!

Heck – I hope they DON’T come to find me – I’m having a great time!
