Living in Michigan, this is one of my biggest fears. Due to the massive lakes that surround us, we frequently get a blast of warm, wet air that causes rain, and of course that warm wet air is being pushed off the lake by a cold front, causing high winds and sub-freezing temps. This combined with large stands of farmland and no trees for windrows means wind blows right across the road and freezes the rain instantly, sometimes right beneath your tires. What was wet a second ago is now frozen, and you can't see the difference. The snow starts to pile up, and a gust of wind pushes you right off the road and into an irrigation ditch. The best 4x4 in the world won't get you out now. And good luck using your cell phone: the areas where this is most likely to happen often have no cell service, or the cell service is only for Verizon phones (too bad you have AT&T, and the FCC forced them to sell off their overlapping network in that area). Four wheel drive won't help. Locking differentials won't help. All wheel drive won't help. All of these require even faintest bit of traction, and you don't have it.

People think I'm weird for having a CB radio in my truck, but last winter during an ice storm I went off the road. Literally all of the county's emergency crews were busy taking care of other ditch parties. I called out on my CB for the local off-roading enthusiasts, and 15 minutes later a snowmobile arrived with a winch. I paid $30 to the man for his help (though he insisted he didn't need payment), and I was back on the road. The CB cost me $250; how much would a tow truck have cost?

This article should be read by everyone who has to travel in winter conditions. Seems like every winter I hear the obituary on the news of people who go off the road and try to hoof it somewhere miles away in a normal winter jacket, jeans, and boots. I keep a snowmobile suit in my truck during the winter. One thing I would have added is something along the lines of "and you knew you couldn't stay in your car with the heat running waiting for help, you'd die from the exhaust fumes". I think that's more common than freezing to death.

The conditions you describe are tough. Going off the road in an ice storm sucks. Love your CB and snow suit suggestions.

The following is not commentary on your situation, but tips to reduce chance of getting stuck:

1. I strongly recommend running a set of good snow tires, no matter whether you have an AWD Subaru or a 4x4 truck or a FWD Corolla. Yes, truck snow tires exist.

The reason is that the rubber compound is much much softer on these tires, and it stays soft when the temperatures drop. All-season tires are much harder in cold temperatures. The tread is also cut into much smaller blocks (known as siping), the edges of which help bite into the ice.

While ice is slippery no matter what, the difference in the grip level between a typical all season tire and a good snow tire is very significant. We are talking 3x the stopping distance. I've seen it on glare ice.

Now, if you really want to be protected, you must buy good studded snow tires. A set of Nokian Hakkapeliitta 7's will make ice seem almost like wet pavement. The amount of ice grip you have with those is unbelievable. The downside is the increased tire noise.

2. Practice controlling skids on ice or snow: practice countersteer, practice NOT hitting the brakes, practice using throttle.

If you can practice this to make it second nature, or at least not foreign, this can make the difference between you spinning and not.

Get out to a snowy parking lot, start turning, let off throttle, then yank the e-brake (and put it down right away). You should start experiencing a spin at this point. No matter what, train yourself to immediately countersteer, such that your front wheels are pointed to where you want the car to go and not where the car is facing.

Now, while countersteering every time, compare the following 3 situations after starting the spin:

A. Counterseteer & do nothing with brake or gas. Simply get your feet off the pedals.

B. Countersteer & hit the brakes.

C. Countersteer & apply gas.

You must actually experience each of these to believe it, but you will learn that it is "C", applying gas, which will get you back in line the soonest. You will notice that as soon as you give it gas, the spin will stop or slow down significantly. You will notice that if you hit the brakes, you spin much further than if you were to simply let go off all the controls.

This is counter-intuitive, but basically if you start spinning on ice on a straight road and you have a FWD/AWD car, applying some throttle will often stop your spin, whereas hitting the brakes almost guarantees a spin. It's worth practicing, if you can.

The reason has to do with weight transfer. Your car's traction at each end is determined by the amount of weight. When you accelerate, you decrease traction up front and you increase traction in the rear. Lifting off throttle increases front end traction and decreases rear end traction, a little. Hitting the brakes massively decreases rear end traction and massively increases front end bite.

Why would you die from fumes inside your car? Provided the air intakes and exhaust pipe were clear of snow, I was under the impression it wouldn't really build up.

This bit about how certain groups of people have somehow developed different responses to cold is fascinating:

Were you a Norwegian fisherman or Inuit hunter, both of whom frequently work gloveless in the cold, your chilled hands would open their surface capillaries periodically to allow surges of warm blood to pass into them and maintain their flexibility. This phenomenon, known as the hunter's response, can elevate a 35-degree skin temperature to 50 degrees within seven or eight minutes.

Other human adaptations to the cold are more mysterious. Tibetan Buddhist monks can raise the skin temperature of their hands and feet by 15 degrees through meditation. Australian aborigines, who once slept on the ground, unclothed, on near-freezing nights, would slip into a light hypothermic state, suppressing shivering until the rising sun rewarmed them.

You have no such defenses, having spent your days at a keyboard in a climate-controlled office. Only after about ten minutes of hard climbing, as your body temperature rises, does blood start seeping back into your fingers. Sweat trickles down your sternum and spine.

[+] ef4|13 years ago|reply
I saw a talk from a US Army-funded researchers on cold weather adaptation. He described how to reliably train oneself to induce the "hunter's response".

You just go sit outside in the cold for five or ten minutes at a time while keeping your hands and/or feet submerged in insulated warm water. The goal is to expose most of your body to the cold while keeping the capillaries open. After about fifty repetitions of this (at three to six repetitions per day), your body gets used to the idea of maintaining circulation despite an overall cold environment.

[+] freehunter|13 years ago|reply
You can notice this effect in your life as well. I don't know where you live, but I know here in the north, 40F is "freezing" cold in November for many people. And when March rolls around, 40F is cause for breaking out the t-shirts. Your body will adapt to the cold to a certain degree. I think I saw it explained on a reddit "ask science" post some time ago, but I cannot remember the physiological details of these temporary adaptations to climate patterns.

Here is a trick I learned biking around in cold Las Vegas nights to warm your hands. Squeeze whatever you are holding hard, (or make a fist and squueze) in pulses about a second apart. It will force the blood through, like a miniature heart, and your hands won't feel cold at all.
[+] munin|13 years ago|reply
there's been some research into the Buddhist monk core/skin temperature regulation. apparently, you can train yourself to do this by using biofeedback, take a digital thermometer and a few hours a day and you can figure out how to raise your body temperature (I know people that have demonstrated this ability).

This topic makes me think of the Jack London story "To Build a Fire", which is one of my favorites. http://www.jacklondons.net/buildafire.html

Also timely, one of our power users at Referly just made a preparedness kit list for winter driving. I probably should have had some of this when driving alone in the Sierra Nevadas last month. http://refer.ly/winter_driving_preparedness_kit/c/789d5ae050...

This topic makes me think of 2012 American adventure drama film co-written and directed by Joe Carnahan and starring Liam Neeson, Frank Grillo, and Dermot Mulroney "The Grey", which is based on the short story Ghost Walker by Ian MacKenzie Jeffers, who also co-wrote the screenplay with Carnahan.

I carry a PLB at all times in my vehicle [1]. In the US this device will summon rescue via satellite. I recommend it for anyone who spends time in remote areas. If you value your life at $1MM and there's a 1 in 3500 chance [2] that summoning emergency services in a remote area will save your life then this is a helpful risk-mitigating tool [3].

1. http://www.amazon.com/ACR-Electronics-ResQLink-Personal-Loca...

2. $280 / $1MM ~ 1/3500.

3. A useful metric might be 911 calls, of which there are 240 million in 2008[4], for the US population of 305 million. If you assume 5% of the calls are life-or-death, that your daily odds of needing to call in remote areas are the same as the country mean, that you spend 5 days a year in remote areas, and a 5-year useful life for the device, then there is a 0.2% chance the device will save your life.

240/310 * .05 * 5/365 * 5 ~ 0.002

[+] jzwinck|13 years ago|reply
Your statistics are seriously flawed. For example, your math in point 2 assumes you will certainly find yourself in a life threatening situation while carrying the device. And your point 3 probably vastly overestimates the fraction of life-or-death calls.
[+] dkarl|13 years ago|reply
I carry one of those when I go backpacking. The satellite transmission they send to summon rescue includes your GPS position, and they also serve as short-range beacons to help rescuers zero in on you when they get close. That can be crucial if the PLB can't get a GPS lock, because rescuers might only know that you're located somewhere along miles of road or trail. If you're unconscious and out of site a few yards from the trail, the beacon might be the only way for them to find you fast enough to help.

Seriously, has anybody created a decent userscript or browser extension to fight this problem yet? I had no luck searching for one.
[+] corin_|13 years ago|reply
Edit, ignore the following:

Worst was where they switched without even mentioning it. One paragraph they're still using F and said "The lowest recorded core temperature in a surviving adult is 60.8 degrees.", then the very next paragraph, with no talk of changing units, they talked about people dying "though temperatures never fell below freezing and ranged as high as 45". Just because the second story happened in England..?

[+] bkanber|13 years ago|reply
This was terrifying, I think because of its sheer realism. Nobody expects they're going to die when they decide to get out of their car and trek to the cabin in the dead of night. But it sneaks up on you through a series of small mis-steps and you could pay with your life for those little mistakes.

Should've stayed with the car. Should've called for help. Once he got out, he should've stayed on the road instead of cutting through the woods. Should've ditched the skis once they broke. Should've exerted himself less.

Lots of little should-haves like those are what can kill someone who's not prepared for and experienced with harsh conditions.

Read this a while back but this passage:

"In 1980, 16 shipwrecked Danish fishermen were hauled to safety after an hour and a half in the frigid North Sea. They then walked across the deck of the rescue ship, stepped below for a hot drink, and dropped dead, all 16 of them."

Damn!

[+] dalke|13 years ago|reply
As far as I can tell, this is an urban legend. That is, several people have looked for an account of this in the Danish papers, and found nothing. Here's one such person's report: http://www.reddit.com/r/todayilearned/comments/15jz7b/til_in...

The closest match was to "Other classic examples of post-immersion collapse include the survivors of the SS Empire Howard (Lee, 1971). The Captain of the ship, Capt Downey, reported: "everyone was conscious when taken out of the water but many lost consciousness when taken into the warmth of the trawler. Nine (out of 12) died shortly after being rescued", where "The SS Empire Howard was sunk by a U-boat on 16, April, 1942.

Some time ago, during the winter we went to visit the Atacama Desert with my wife (she was born there). We rented a small car and my wife told me "are you sure this will work at 4,000 meters high? (13,100 feet)" - we were going to be travelling around some small towns and one of the roads reached that altitude. Stupidly enough, I replied to her "sure... these are modern cars, with fuel injection and smart oxygenation".

The roads were covered with snow, and suddenly we got stuck in a snow-covered road. Being a firefighter (trained in rescue) I had some idea of what I had to do... but of course, no shovel or any other tool to remove the snow. For 1 hour or so I tried to remove the snow with no luck. I got into the car, told my wife that the smartest thing would be to stay in the car. If necessary, the fuel in the car would keep us worm for days.

After some time, a car came down the road and helped us out... only to get stucked again, this time because the car actually got de-oxygenated at exactly 4,000 meters... Luckily this time the same car was behind us for a few minutes and we could push the car until the downhill.

Now we tell the story with friends and laugh about it. But if you ever go to some place that you have a slight chance of getting stuck in the snow: pack a shovel or at least make sure you have the fuel tank full. And never get out of the car wandering to find something.

Although that is sound advice in the event you're caught in a small rift of snow, it will mean nothing when hitting a ditch that sinks your car to the frame in snow which is often the case in situations that the story illustrates.

Have somebody used it, ever? I did, once. Tyres just throws mats under the car, without much movement. If there's no friction between tyres and ice, there would be not friction between mats and ice, either. However, it could help on the snow or sand.
[+] gav|13 years ago|reply
I used to carry kitty litter in the trunk of my car when I lived in Vermont. Throwing a couple of handfuls under your tires would give enough traction to get going on ice.

That was a fantastic read. Incredible journey to hypothermia and back.

The description of the feeling of burning is unreal! What is even better is the incredible knowledge of how to revive a patient from this state.

I belief these techniques are used in heart bypass operations ?

[+] sanotehu|13 years ago|reply
Yes, they are indeed. As a medical student I had the privilege of seeing a heart valve being installed. They are a witness to how far medicine has progressed since the days of barber surgeons.

The blood is taken out of your body through the femoral vein (under the skin between your hip and your nether regions), taken through the perfusion machine and pumped back into the femoral artery. Because at this stage the heart will have been stopped, the high pressure in the femoral artery makes blood flow backwards up the aorta, where it supplies oxygenated blood from the machine to the whole body.

At one stage the flow has to be switched off in order to sew the metal valve onto the top of the aorta. In preparation for this, the blood leaving the perfusion machine is chilled (I'm not sure to what temperature). This slows the body's metabolism down and would cause hypothermic stupor if the patient had not already been under anaesthetic. I was told by the perfusionist that this gave the surgeons around an hour of extra operating time before the brain's oxygen content dropped to dangerous levels. All this is of course monitored by the anaesthetist and the perfusionist. The hypothermia will be reversed during the process of reviving the patient.

With the advent of endovascular procedures, this sort of surgery is becoming a rarity. It's much easier to pass a small tube up the aorta and inflate the narrowed artery from the inside than it is to open up the chest and sew a new blood vessel onto the heart. Of course, the medicine's more boring but it's all about getting a good outcome for the patient, isn't it?

Being cold and being deathly cold are two different things.

I've only gotten mild frostbite once, but I'd never want to have it again. The skin blackens and peels, and itches like nothing I've ever experienced before.

[+] ghaff|13 years ago|reply
Frostbite and hypothermia are two different things and often happen under different conditions. As noted, you can get hypothermia in (relatively) mild temperatures if you're wet, tired, dehydrated, etc. Frostbite tends to be the result of colder temperatures often in conjunction with wind. But, yes, both are bad. I've also had fairly mild frostbite of the ear lobes (a pretty common place) and it's not fun. The thing to be aware of though is that it doesn't have to be especially cold to get hypothermic. In cold weather hiking, some of the conditions you need to be most careful in are 35 degree or so rain.

Where did you get that information? The Inuit traditionally use a qulliq/kudlik (a lamp fueled by seal oil) for light, heat, etc. and everything I can find now says that it's not something introduced in the last couple of hundred years. For example,

http://books.google.se/books?id=G49CwQpozoUC&pg=PA29&...

says that Inuit were curious why people were hunting whales for oil for light, when they knew that seal oil was better for the qulliq.

Ahh, even better. The Dorset culture (http://en.wikipedia.org/wiki/Dorset_culture - 500 BCE–1500 CE) used soapstone lamps very much like the the qulliq for heat.

One thing I have started doing when I go on any outdoor treks, even just a day of snowboarding, is carrying a portable amateur radio. I program in the local repeaters if there are some (not always an option depending on area) which greatly extends range if necessary. Not as good as a PLB in some ways, but superior in others. For example, I can call for help without bringing in the whole cavalry.
