More thoughts on portaging

Portaging 102: Troop 48's 2017 Algonquin Park Expedition

But If You Do Get Lost – Emergency Shelters ©


 
You are “misplaced” in the woods and this is your bed tonight, picture by the author.


So, it happened!  It had to happen to you eventually, you know; it happens to everyone eventually.  Maybe you got turned around and now you are “misplaced”, and you have no idea on how to get back to where you were.  Maybe, you slipped and fell, and now you are too injured to get out of the woods by yourself.  Or, maybe the Sun is going down behind the trees and you have less than two of daylight left.  What do you do now?

You need to find shelter, of course!  But what should you look for?

Summer or winter, it doesn’t matter, the elements are your worst enemy; humans can’t survive heat or cold, wet or wind for long without a shelter.  Because protecting yourself from the elements means different things in different climates and at different times of the year, the type of shelter that you build will depend on where and when you are building it.  It is true, that a lot could, and has, been written about how to build a shelter, however today, I am writing about things that you should think about before, and as, you build your shelter.

Location, location, location…and the 5 W’s

Whenever you set up a campsite in the wilderness, you should always consider the 5 W’s, wind, water, widow-makers, wood and wildlife, before you choose a location.

Wind

You must treat wind with respect and plan for it when you choose the location of your shelter, because in a survival situation wind can be your enemy and kill you fast if you let it.  Wind and wind-chill it can lower the “real-feel temperature” and bring on hypothermia; it can suck the moisture out of you and bring on dehydration, or it can blow down branches and trees on you and squash you flat.  On the other hand, wind can blow mosquitos and other bugs away from you and your campsite.  So, what type of winds are there?

 
Prevailing winds worldwide, from Moon Joon Kim


Prevailing winds are, according to the Oxford dictionary, “a wind from the direction that is predominant at a particular place or season”.  It is always important when you travel or camp in the wilderness to know the usual wind direction, when canoeing it can help you stay in the calm water on the sheltered lee side of the shore or if you put your camp on the windward shore, it can help blow the bugs away from your camp.  It is important to remember that prevailing winds are not constant all day long, as Alan Innes-Taylor noted on page 53, when he wrote of prevailing winds in the Arctic Survival Guide: “Fair weather winds usually decrease at night”.  In Algonquin Provincial Park and much of northeast Canada and the United States, fair weather winds usually blow from the northwest to the southeast during the day.

Offshore winds, from Fig. 2-11, Aviation Weather Student Guide

Offshore, onshore and valley winds are all very similar and are both generated by the daily warming and cooling of the land.  The differences in the specific heat of land and water causes the land to warm and cool more quickly than water, during the day this causes warming and rising air over the land and descending or cooling air over the water resulting in an onshore or sea breeze.  At night the process reverses with the land cooling quicker faster than the water, which cause descending cool air over the land and rising warm air over the water and creates an offshore of land breeze.  Onshore breezes seldom penetrate far inland, but they are usually stronger than offshore breezes. 

 
Mountain and valley winds, from Fig. 2-12, Aviation Weather Student Guide


In the daytime mountain slopes and hillsides are heated more quickly by the Sun than valley bottoms, and these slopes warm the surrounding air through conduction.  This warmed air rises and then later cools and sinks back down towards the valley floor, forcing the air from the valley floor up the mountain or hillside, completing the cycle of circulation and creating an upslope and up valley wind.  At night the air in contact with the mountain slope or hillside cools faster than the valley bottom because of outgoing terrestrial radiation and this denser cool air flows down slope and down valley and forces warmer valley bottom air upwards, creating a circulation pattern and downslope and down valley winds.

 



Excerpts from the Arctic Survival Guide, p. 53, by Alan Innes-Taylor


  
All of this is important, because you want to face your shelter so that the front is perpendicular to the general flow of the wind.

Water and Widow-makers

The second and third of the 5 W’s are water and widow-makers.  While you want to be near drinking water, setting up your shelter near that babbling brook is often a bad idea, as a storm far upstream can quickly turn that tame stream into a raging torrent and wash you away.  Also, you should look for a level area half-way between the summit of the hill and the valley bottom, as the cold night air  collects in low spots and valleys and the summits of hills are always cold.  It is often significantly warmer half-way up a hillside, between the crest of the hill and the valley bottom and far safer from flooding.  Always look up and around your planned campsite and make sure there a no dead trees, snags or widow-makers stuck in the branches above you, just waiting for the right wind to come crashing down on you.  And lastly, don’t shelter under the tallest tree in the forest, it is a lightening rod!  If possible, shelter in a grove of equal sized trees.  Also avoid hill-tops and exposed cliff faces can also attract lightening, so don’t shelter at the base of the tallest cliff in the area or on the top of the hill.

Wood
  
An excerpt from “How Not To Get Lost”, by Charles Elliott


The fourth of the 5 W’s is wood, the area that you choose for your campsite should have plenty of firewood and building materials, such as leaves, boughs, bark, branches, etc.

Wildlife

The last of the 5 W’s is wildlife, be careful of setting up your shelter on game trails, near swampy areas that breed mosquitos or in a rock shelter that is already called home by one of the locals.

And now that you have some ideas on where to build your shelter, the first and most basic shelter you need, is the one that will insulate you from the cold, cold ground.  If you have ever slept directly on the ground, when the night-time temperatures drop close to freezing, as I have once upon a time, you will know how painful it is as the ground sucks the heat out of your kidneys!  I can tell you from personal experience that, insulation between you and the ground is your friend.  You should always build a shelter bed before you build any other shelter.   Mors Kochanski, a well-known survival expert, wrote that shelter beds or emergency bough beds should have a compressed thickness of at least 4 fingers or about 3-1/2 inches of dead air space between you and the ground or snow as insulation.  Earlier in 2019, I experimented with making a bough bed and discovered that a 28 inch (72 cm) high pile of boughs compressed down to 18 inches (46 cm) of insulation when I sat down on it.  Shelter beds insulate your sleeping body from the cold ground and make you more comfortable and allow you to sleep better.  For more on shelter beds, read “Making an Emergency Bough Bed”, HERE and watch “Building An Emergency Bough Bed”, HERE.

There are two types of shelters, found shelters and built shelters, and of most are reflector shelters.  Found shelters are exactly as they sound, shelters that you find in the wilderness and they can be a rock shelter, cliffside or big boulder, a blown down log or an uprooted tree; or simply a large tree that you can lean against during the night.  Built shelters are lean-to’s, debris beds or double trench fires, these last two are the only two that are not reflector shelters.  Reflector shelters are any open or roofed shelter where you are between the reflector and your fire.  Lean-to’s or debris shelters take more time and energy to build but, are the most weatherproof of shelters.  Below are some examples of shelters that you could find or build in an emergency.

This is a thumbnail sketch of building or finding a shelter in a survival emergency.  Hopefully you will never have to build or find one in a real emergency, however they are a lot of fun to find or build for practice.

The Trinity of Trouble ©



Arctic Survival Guide, 1964, edited and compiled by Alan Innes-Taylor

  
Recently I have been reading the Arctic Survival Guide, a rather hard to find survival guide; by Alan Innes-Taylor1, an early expert in northern survival.

“…survival is terribly unforgiving of excessive optimism, carelessness, and neglect.  Remember these three – they are the trinity of trouble…”, Alan Innes-Taylor, Arctic Survival Guide, p. 46

This guide was written in 1964, for the aircrews of the Scandinavian Airlines Systems (SAS), and on page 46 the author wrote about the “trinity of trouble”; which he explained was excessive optimism, carelessness and neglect.

The trinity of trouble seemed to me to be an easy to remember survival rule and so today I am going to write about the things you should not do, if you want to survive an emergency in the wilderness.

Unfortunately, Mr. Innes-Taylor, on page 46 in the Arctic Survival Guide, never fully explained what he meant by the statement “…excessive optimism, carelessness, and neglect…”.

However, in the Arctic Survival Guide, he did include two statements that provide some insight into his thinking.

To date, reviews of polar crashes continue to reveal avoidable hardships due to overestimation of personal capabilities.  In too many instances deaths may be attributed to lack of appreciation for the physical demands of the conditions as actually found, Alan Innes-Taylor, Arctic Survival Guide, p. 46

Finally, the infrequency of crash landings can lull the participants on long flights over the polar regions into a false sense of security resulting in non-survival when all have landed safely, Alan Innes-Taylor, Arctic Survival Guide, p. 48

Another source which offered some insight into Mr. Innes-Taylor’s thoughts on the trinity of trouble, is the book Northern Survival, which was originally compiled in 1967.  Mr. G. D. Cromb, who wrote the foreword, credited a number of unnamed contributors; however he only mentioned one contributor by name, “Mr. Innes Taylor of Whitehorse who had first-hand knowledge and experience in northern Canadian living”.

I believe that the following quotes from Northern Survival, if not directly from the mind of Alan Innes-Taylor, are certainly derived from his thoughts.

The mental attitude that ‘it can’t happen to me’ is dangerous in that the individual will not accept the situation as it exists and is blind to reality, Northern Survival, page 5

Most people are inclined to over-estimate their physical abilities.  Be very careful when trying to estimate your physical stamina…, Northern Survival, page 5

I believe that what Mr. Innes-Taylor was trying to communicate with the phrase, the trinity of trouble, is that “excessive optimism2 and the “it can’t happen to me3 mental attitude, leads a person to have a “false sense of security4; which leads a person to have an “overestimation of personal capabilities5, their “physical abilities6 and “physical stamina7; and finally to have a “lack of appreciation for the physical demands of the conditions as actually found8; all of which contributes to “non-survival9.  Additionally, I further believe that he intended it to be understood, that excessive optimism, leaps directly to carelessness and to neglect.

But to expect is not enough; you must anticipate and prepare for the unexpected Survival: Training Edition, AF Manual 64-3, page 1-4

So, if excessive optimism leads directly to carelessness, then what are some examples of carelessness?  Carelessness following an emergency in the wilderness usually involves not anticipating and preparing for the unexpected.  Some careless errors that you might slip into include; wasting resources, supplies or opportunities by not preparing in advance, perhaps by not building a shelter before the storm arrives, or signals, before you hear the rescue plane; by delaying setting up camp or not turning back on the trail until it is too close to dusk; or by not sleeping and resting when you have the chance or it is in your best interest to be out of the elements.

…it pays to prepare for any eventuality by carrying on your person a personal survival kit, Survival: Training Edition, AF Manual 64-3, page 1-4

Examples of neglect, which follow carelessness, generally involve neglecting to prepare for any eventuality in some way or the other.  Perhaps you have failed to leave a detailed travel plan with someone.  You should always leave detailed travel plans with someone at your base of operations, these plans should include who is traveling, where you are traveling, when you are leaving and when you plan on being back.  Another example of neglect would be failing to prepare for emergencies by neglecting to carry a personal survival kit, first aid kit or other emergency supplies.

“…no matter how well prepared you are, you probably will never completely convince yourself that ‘it can happen to you’…”, Survival: Training Edition, AF Manual 64-3, page 1-6

However, as Survival: Training Edition mentions, you will probably never be able to fully convince yourself that it can happen to you and if you are not careful you can unconsciously slip into the “it can’t happen to me” attitude and from there into “excessive optimism, carelessness, and neglect”.  So do your best to remind yourself that it can happen to you, prepare and anticipate for any emergencies and finally don’t neglect to file a travel plan or to bring a survival kit and emergency supplies along with you.

Notes

1 So who was Alan Innes-Taylor


Charles Alan Kenneth Innes-Taylor, from the obituary by Philip S. Marshall, which was published in Arctic, Volume 37, No. 1, March 1984.


Charles Alan Kenneth Innes-Taylor, who went by the name of Alan Innes-Taylor, experienced the switch from riverine roads travelled by canoes, steamboats and dogsleds to asphalt roads and airplanes and he witnessed the change from the heroic age to the modern age of exploration.  He was born in 1900, in London, England, and his family moved to Toronto, Canada when he was eight.  During World War I, when he was 17, he enlisted in the Royal Canadian Flying Corps (RCFC) where he learned to fly: beginning his association flying and aircraft that continues until his death.  Following World War I; he began to move north, working first with the Canadian Mounties, where he learned dog-mushing; after that as a miner at the Treadwell Yukon Mine in Keno Hill and after that as a purser on the steamer the SS Whitehorse.

It was his northern Canadian and Arctic experience that uniquely qualified him in 1929 to bring replacement sled-dogs to Admiral Byrd’s BAE I Antarctic expedition.  He returned to the Antarctic with Admiral Byrd in 1933 as the chief of field operations for the BAE II Antarctic expedition.

At the start of World War II, he was commissioned, by a special act of the American Congress, as a Captain in the U.S. Army Air Force.  He first helped rescue down air crews from the ice sheets of southeastern Greenland.  Later from mid-1942 to the end of the war, he trained arctic and mountain troops on how to survive and operate in these frozen environments. 

In 1950, with the start of the Korean Conflict, he helped to make possible the first commercial air flights over the North Pole from Stockholm to Tokyo, by the way of Anchorage; which was pioneered by Scandinavian Airline Systems (SAS) in 1957.  He wrote two survival guides for the SAS aircrews; This is the Arctic: Arctic Survival Guide, a 54-page guide in 1957 and finally, The Arctic Survival Guide, a 137-page survival guide in 1964.  He also invented specialty Arctic survival gear for them, such as exposure suits and 4-person sleeping bags.

The Fall Equinox Isn't On September 21st? ©


 
Autumn in Minister Valley, Pennsylvania; photo by Kathleen Reynolds


In “How to Find Your Way Without A Compass, Part One, Orientation By The Sun” (HERE), which I wrote earlier this year, and in “Part Three, The Shadow-tip Method” (HERE); I wrote that in 2019, the Fall Equinox will be on September 23rd.  Since I published these articles, I have received several questions regarding the 23rd as the date of the upcoming equinox.  

 

Most people wondered if I had mistyped the date, since accepted, common knowledge is that the Fall Equinox is on September 21st, the Spring Equinox is on the 21st of March, the Winter Solstice is on December 21st and finally the Summer Solstice is on the 21st of June.  Unfortunately in this case, common knowledge is only mostly right and the various equinoxes and solstices occur, either one or two days before or after the 21st, and for the most part, very rarely on the 21st.


But why is that, you ask, or at least that is what I asked myself, and so maybe you asked it too.  I didn’t know the answers, so I did some research, because that is what I do; and here are the “whys” and the “whens” of our yearly equinoxes and solstices.

Everyone knows, that on the coming Fall, or as it is more correctly known, September Equinox1 the Sun rises exactly in the east and sets directly over the west.  But what causes an equinox and why is it on September 23rd, in 2019, and not on the 21st?


Earth’s Axial Tilt from “The September Equinox”, by www.timeanddate.com


Equinox is from the Latin, “aequinoctium”, meaning “equal night” and there are two equinoxes every year, one in September and one in March.  On these two days, the length of day and night is nearly equal at roughly 12 hours each, all over the world, and that is why they are called equinoxes.  Also, on both of them the sun rises in the east directly over the Equator and sets directly over the Equator in the west; because on these days the tilt of the Earth’s axis is perpendicular to the Sun’s rays.  The equinox occurs the moment the sun crosses the Earth’s celestial equator, the imaginary plane in the sky that extends directly out from the Earth’s equator and the exact date and time of this occurrence varies from year to year.  The March Equinox is both the beginning of spring in the Northern Hemisphere and the beginning of fall in the Southern Hemisphere and the September Equinox, which in the Northern Hemisphere is the beginning of fall, is also the beginning of spring in the Southern Hemisphere.

Most often the September Equinox falls on either the 22nd or the 23rd. Less often the September Equinox is on the 21st or the 24th; the last time it was on the 21st was in the year 1000 and the next time it will fall on that day is in 2092.  Also, the last time the September Equinox fell on the 24th was in the year 1931 and the next time will be in 2303.

The same pattern occurs with the March Equinox, which happens most often on the 20th, and less often on the 19th.

Solstice is from the Latin “solstitium” and it means “sun-stopping”.  There are also two solstices every year, and depending on which hemisphere you are in and they are both the shortest and the longest days of the year.  In the Northern Hemisphere, the June Solstice is the longest day of the year and the start of summer; while in the Southern Hemisphere it is the shortest day of the year and the beginning of winter.  Six months later, on the December Solstice, everything is reversed and it is the shortest day of the year in the Northern Hemisphere and the start of winter and it is the longest day of the year and the start of summer in the Southern Hemisphere.  Solstices occur when the Sun’s zenith is at its farthest point from the equator.  On the June Solstice, the Sun reaches its farthest point north at 23.4o north latitude; the North Pole tilts towards the Sun and the Sun is visible all night from just south of the Arctic Circle to the North Pole; and the Sun rises to the north of east and sets to the north of west.  Also, south of the Antarctic Circle, there is no sunlight at all on the June Solstice.  On the December Solstice, the Sun reaches its most southern point at 23.4o south latitude; the South Pole tilts towards the Sun and from just north of the Antarctic Circle to the South Pole the sun remains visible all night; and the Sun rises to the south of east and sets to the south of west.  From approximately the Arctic Circle to the North Pole, the sun remains below the horizon all day and there is no sunlight at all.

Most often the June Solstice occurs on the 21st and only slightly less often it occurs on the 20th.  Similarly the December Solstice, at least for the next 30 years, happens only on the 21st.  So, in the case of the yearly solstices, common knowledge is mostly correct.

In the end though, common knowledge is close enough because as Richard Graves noted when he wrote about equinoxes on page 330 of, The 10 Bushcraft Books, “…for about two or three weeks either side of the Equinoctial periods…on any day between March 1st and April 14th or September 1st and October 14th…” the Sun rises and sets close enough to the true east-west line to use the sunrise and sunset to orient yourself.  Similarly, for about two to three weeks on either side of the solstices the Sun will be close to either its northern or southern zenith.  So whether it is the 19th or 24th, 22nd, 21st or 23rd; it doesn’t really matter when all is said and done.

Notes

1  I accidentally fell into a Northern Hemisphere-centric bias when I wrote my earlier articles in the “How To Find Your Way Without A Compass” series.  Seasons are opposite each other on either side of the Equator, and so using the descriptor, “Fall” for the coming equinox is both inaccurate and a bit of a misnomer, since the equinox that takes place in September is the Fall Equinox for the Northern Hemisphere and the Spring Equinox for the Southern Hemisphere.  Additionally, using “Spring” for the March Equinox and “Winter” and “Summer” for the December and June solstices is also incorrect.  My apologies to all of my readers, south of the Equator.
