What a shame. ATVing in the middle of the night in the high desert, in freezing temperatures? FYI, the desert is deadly in the winter too. From CNN

I read this story earlier on another news website which has more details here.

Sad for the families to have to go through through this right before Christmas and starkly shows the danger of riding around in rugged desert terrain during the middle of the night.

What a shame. I feel bad for their families. It will be interesting to hear more details as they come out and ponder what they could have done differently, or ratyer what we think we would do differently.'A ravine with steep terrain in a desert that big could be dangerous any time, day or night. It obviously wasn't easy to find them even though the searches knew their last know location and their intended destination. A PLB and/or cel phone may have helped but we don't have enough details to kow yet.

That is so sad. Christmas will be solemn for their families for years to come.

RIP

When I hear a story about someone doing something this stupid I usually assume alcohol was somehow involved.

I am willing to state that you may well be right, but why make the assumption?

One of the more discouraging things about SAR work is the high percentage of serious incidents in which alcohol is involved (and not as stove fuel). It actually made a virtual teetotaler out of me.

Just really not enough info re: cause of demise.Did they crash,Exposure,Dehydrate,what?

they drove off a 500' cliff. bodies found 400' down. vehicle another 100' further down.

more details here

they were found in the opposite direction from where they told people they were going.

So they have basically Darwined themselves.
One has to wonder if they believed their position to be somewhere else.
Only merciful thing about this is that it would have been extremely quick.

Is this a fact? A 30' fall usually kills? That's around 3 stories, I guess. It seems that people have survived that jumping out the window in fires.

there are a lot of variables - age, elevation, striking things on the way down, etc.

go here to learn about how a window washer survived a 47 story fall: story

and here for a medical study from 1971 that breaks down 200 surgical cases of people who fell: surgical study

bottom line - (1) do not hit your head ( no, duh ), and (2) try to not injure your pelvis - it's a leading indicator for increased mortality rates.

and then there's stewardess who holds the world's record by surviving a 33,000 foot fall without a parachute - although she was surrounded by an airplane: Ms. Vesna Vulovi

close hijack

I suspect there may be a big difference in survivability in falls depending upon whether you are talking about urban situations or wilderness environments; aid generally arrives a lot more quickly in an urban setting.

The rule of thumb I developed ater experiencing the results of several fall victims was that fall heights of over 40 feet were usually fatal. I can recall one fatality who fell a mere ten feet and I think I remember one who survived a 50 foot fall. And then there was the guy who fell about 300 feet - definitely DOA.

Much depends upon the surface upon which you land. A rocky surface is typically rather bad. Consider also the nature of the fall. Are we talking a free fall or a sliding fall where the victim might not build up so much speed.

There are instances of climbers surviving fairly long fall - well over fifty feet. Those were cases where the belay system worked to slow down the impact. There are plenty of fatalities at lesser heights as well.

I would not wish to experience a fall of thirty feet, especially a free fall. I have walked away from sliding falls around thirty feet in length - I can recall about two instances, but I an not anxious to push my luck.

Another hijack...

I fell from 30' off the side of a rock bluff. As I was falling I luckily hit a tree branch. I grabbed hold and rode a what turned out to be a small tree gently to the ground. I landed standing up. It was incredible. I will never forget that one.

End hijack. merry Christmas. Ok now end hijack.

"

Don't know of that is true or not.
But if it is - I am one of the lucky few.
I took a 25-30 foot leader fall while rock climbing many years ago. Came away with a bloody nose and a broken ankle. Could have been much worse.

There are infamous stories of people who took longer falls - and died. But death was not immediate. One guy got up after a 60-foot fall, and was talking to people for half an hour. But eventually died due to rupture of his spleen and internal blood loss.

As far as the original story is concerned .... the desert is tricky at night because the lighting can be very sharp. If there is a full moon (or mostly full), bright areas are quite bright and shadows can seem very dark. The visual cues may have deceived these guys into believing they were on less dangerous terrain than they actually were.

If your belayer was on top of things, the force of your fall would have been lessened by the stretching of the rope. Leader falls of that length and longer are not incredibly uncommon in rock climbing, but it is not the same thing as taking a thirty footer unbelayed without any deceleration and just going splat! on the ground.

Falls of any type depend on the person(s) definition of a fall.

For example: A 30 foot fall while roped into a belay system is not the same fall as a 30 foot fall down a cliff where your "fall" may be slowed up by undergrowth etc and you do not suffer any significant injuries and walk away. In other words, your fall was mostly a slide and tumble down.

Another example: If you did indeed free fall 30 feet off a cliff without being slowed on the descent, you may land on fairly soft terrain and walk away. If you are not quite so lucky, a bone fracture may of occurred but you are still in one piece and live another day.

On the other hand, a 30 foot free fall of a cliff onto some rocks at the bottom will probably result in some major injuries if not death.

Again, the definition of the fall must be ascertained and put into perspective when discussing.
