Good question.

Whether or not I could survive would depend a lot on what type of cold setting we're talking about. If it's in the woods, constructing a shelter (out of trees, rocks, etc) would be a lot easier than if I'm on a vast empty expanse of the arctic where the wind would be brutal. Also, is the presumed wildlife? That makes a big difference in the food factor.

I have to agree with Bowman, I think I'd be ok but its hard to say without being there. I think I've watched Man vs. Wild enough to know a few survival techniques that would come in handy and enough camping experience I would survive a couple days at least.

Survive? Without a cell phone and a computer? About 1/2 hour!!!!

in all comes down to what your willing to do or eat to survive & & also in there an avalible water source near by if need be ice can be broken with a rock if snow eat in in mite not be good but it helps

I have never gone into the wilds as ill prepared as is described in the scenario. Minimum that goes into my fanny pack (or back pack)when I going into the field is a space blanket,some paracord, 8X8 3 mil plastic tarp, small first aid kit and 3-5 ways to start a fire. I collect lint from the dryer and keep it in a 35mm film canister. I also take OOOO steel wool sealed in a zip lock bag. I have a magnesium fire starter bar that I have shaved down, and those shavings are kept into a 35 mm film canister. I have made firestarters from dryer lint put into cardboard egg cartons that I filled with paraffin wax.
I carry several flint and steel devices as they will work even when wet. Having done SAR many years ago, I have heard too many stories about lighters causing more damage than they were worth.
The OOOO steel wool takes a spark very easily. Light fanning it will produce a decent flame that will get the paraffin starters going. The paraffin starters will last about 5-10 minutes depending and the quality of wax you have. Dry dryer lint will also take a spark and produce a nice flame.
I have more flint and steel devices than I can count. Strike Force is one that comes to mind. I seldom carry matches with me at all. Especially the "gopher" cardboard packs, you know light one and "gopher" another.
I have never used a match to light my fireplace, only flint and steel and the items mentioned above. That way I keep my skills up and in a crisis situation, I won't be too stressed to do it right, it's an ingrained behavior.
The tarp and paracord can be used to make a shelter. It not hard and takes up very little room in my pack. Just practice with the stuff before you go out.

Shipwreck, Thank you. I am of the persuasion that if you are prepared for a "survival" situation, you probably won't have one. I have been in situations in the boonies that some would consider, uh let's say uncomfortable, that I tolerated rather well as I was covered for the circumstances. Also, I don't feel the need to show off and fish naked in the pond. I believe in caution,(my wife would choke hearing that)in the areas that can kill me. I have had my share (my wife would say more than my share)of nearly coulda been fatal instances and have worn out more than my fair share of guardian angels.
That said, experience has been a good teacher, there are some things I know NOT to do again. And since I've gotten older I am less likely to try to scale mountains like I used to do in my twenties, specially since I learned that when I break now, it takes longer to heal.
3 years ago on an elk hunt, the thought I had as I was sliding down rolling scree on the side of a mountain toward the edge was, "My wife is gonna kill me." I was able to stop about 5-6 feet from the edge. I caught my breath and looked over the 50-60 foot drop and realized that she wouldn't have had the chance. It would have been at least a day before SAR found me and the carrion eaters would have had their fill before I was found. I couldn't get out of bed the next day without a great deal of difficulty. 35 years ago, it would have been no big deal.

Well you have all the materials needed to stay alive as long as you are not badly injured. As you have all said it depends on the weather, terrain etc. First things First. Set yourself up a base and dont wander too far. With a base camp once you have a fire going you can keep it going cause every time you leave for another area its going to cost you matches for one thing. Set up a help sign so aircraft can see it etc etc. I prefer to carry a Scuba Knife with a hunting knife as it does not rust, retains its edge a lot longer and is also heavier in the event you have to hit something. It also will suffice as a shiney reflector to an aircraft. Then kick yourself for not letting someone know where you were going and an ETA.

Please, I live in ALASKA...thats a walk to town for me...next...

You Northern boys must be snow blind .If you have never been in the swamps at 100 degrees and 99% humiditity you don't have a clue you have never seen a rattlesnake seven feet long that can kill you even in the hospital.Bacteria everywhere you feet will rot on the second day.You have heard what the boys in vietnam went through it's just as bad.

Hey there Bo you see those bad bugs in the main page ,thats "some "of the bugs i was speaking of you never seen one of these in a snow bank have ya.I have lived a long life and spent time in the cold it's tough i'll admit but as you know you can dress for it.The heat is unescapable smoldering,stifiling.There are so many bacterial microbes that will put you down so quick you want know what hit you.You don't have to drink it,it just migrates through your skin.I'll take a bear anyday at least i can see him coming.An old hog can be a very tough adversary an he will eat you too if he gets the chance.

The snow and the cold can be a blessing as well a threat,being able to preserve a large kill and to stop spoilage.Keep down the vermin flies,skeeters,tick etc.Although travel in these conditions only amplifies the need for extreme caution.No place for a damaged limb,head injury or any other malody that can occur in such conditions as snow and ice.If prepared for this,a week in a fixed position should be of consequense.My thoughts are this if your mind is right the demons and wild beast of the forest can not prevail.Have your back against a rock and keep your powder dry.The rest is in your head.Didn't mean any disrespect toward our brothers to the North .

Ohio Hunter, There is always a chance the wind will pick up and in less time than you realize all your tracks are gone. It is situations like that, that will bring out the SAR guys, IF, BIG IF, you remembered to tell anyone where you were going. I can make a shelter that will get me through until the weather gets better or daylight. Didn't say it would be real comfortable like home, but I won't freeze and won't feed the coyotes or other critters out there either.

At first i was thinking of a healthy person,but then i started to reevaluate this situation .I myself have a heart condition there is that constant varible,broken leg,arm snake bite heart attack or some other mishap.I have been told to stay out of the woods but it is where i come from.I have been thinking about locator devices with a emergency alert.Maybe not to bad an idea if you have the cash which i don't.A disabled hunter puts a new twist to the question.May the woods remain your sancutary,It'where i plan to spend eternity ,Oak tree for a head stone.
