I have read Shakespeare and have taken to heart his warnings :wink: Actually one of the highlights when walking is bumping into forum members on the tracks. And now is it is time to say thanks to Nik and Adam for all the hard work in turning what would be strangers into people to know.

Cheers Brett


G'day Brett,
You should read Robert Burns especially this one if you can "Is there for honest poverty" kind of leaves the Bard behind.

Yup. Your having a warmer winter, meanwhile 200km up the highway, we've had colder than average nights and about spot on average days. It only got down to 8 here last night too, and more warm nights are forecasted whilst this rain hangs about, but its soon to drop below freezing by the weeks end.

No, just a TKD 2nd Dan. Though out of training for a few years.
See, a lot of it is knowing where to hit someone, as much as how to do it. Technique counts far more than size.

It's been up and down over here. A cold spell, then a bit warmer, then quite balmy, then cold again and now we're having another loverley warm bit. I was in shirtsleeves today. Of course, that may just have been 'cause I was working so hard . . .

A couple of weeks ago I was camped on snow for 3 nights, at an altitude of 1200 metres, up near the Parthenon at the Labyrinth.
One night it got to minus 4.9 at Cynthia Bay. That's about 740 metres in altitude. Allowing 1 degree for 100 metres, that makes it approx minus 9.5 where we were. I know it was cold. There was a high over the state and the night sky was perfectly clear. It was remarkably still, and the stars were so bright I could see the milky way from the southern horizon to the northern horizon. You could make out galaxies above us if you stared and got your eyes used to it.
I spent half an hour walking around on the snow with wet boots and no socks to get some night photography of it. Still working on my results (more important stuff to do so it's on the backburner) but it really was amazing...
But, COLD!
First time ever I slept with 8 layers on my body, plus the silk sheet and the Mont Franklin sleeping bag, and a thermarest, space blanket (on floor of tent), tent floor, tyvek. Still cool, but quite able to get some sleep.
There was no condensation, there was frost. You sit up and brush your beanie on the tent and you have to shake the ice off outside the tent. Not the first time I've had that.
That walk really got me thinking about carrying a small thermometer / digital recording device to find out how cold it really does get overnight in some of these places.

Green with envy, Adam, it sounds marvellous.

But the thermometer's bad idea. Leave it a mystery. There are some things we're better off not knowing.

Adam with respect first mistake wandering around with no socks in wet boots in very cold conditions second going to bed so cold that you required so many layers third having a tent that when you sat up your beanie made contact with the inner fifth not being a native born Tasmanian or originating from cooler climes :lol: :lol: :lol:
You did have fun though I suspect .

The height of the tropospause increases with latitude as you get closer to the equator from the poles. At the pole its 25000 feet or so and at the equator it can be 60000, it wavers a bit all the time. It can dip slightly below the summit of the highest 8000m peaks every now and then,making conditions there unsurvivable.
This is relevant to the temerature and severity thing re NSW vs Tas because the same altitude condition, temp vs air pressure, are actually at a slightly lower height above sea level in Tassie because of its latitude.
I think the wind chill suggestions are spot on. I live next to the Brindabellas and near the Snowys nowadays, and its always apparent that the mass of moving air at our height that forms the prevailing wind, has been travelling across quite a lot of land before it arrives here,including a lot of mountains. The same in the Victorian alps to a lesser extent,sans the other mountains. On the mainland, the closer you get to having mountains that are exposed to it coming off the sea, the more the conditions get to be like Tasmania. The BawBaw plateau would seem to get more extreme dips of cold, anecdotally speaking, than many areas of the snowys.
The Snowys do seem to be a lot drier, I'd imagine that the really exposed places, the summits of Townsend, Kausiosco,and possibly Bogong, get some pretty wild drops when the winds are really blowing.
These days, tiny low power datalogging gear for recording temperature and other stuff can be had really cheaply and easily. Maybe some of us in different areas could aproach parks authorities with a view to temporarily leaving some in areas of interest. If the data is of interest to somebody in establishment and responsibility is taken for retrieval it could be a goer. :idea:

BA: Weather Monitoring While on a Bushwalk has some information on wristwatches that log the weather, but are not good at airt temp unless you take the watch off your wrist. Dick Smith and Paddy Pallin also have small weather stations.

I'm with NNW though: I can tell when its cold by the frost on my tent and whether my boots that I have left in the vestibule have frozen when I wake up, as happened on a clear night at Mt Anne . Not sure that I want to know how cold!

Am I the only one that has done that? Do I not have the brains to do something about it if it's a problem? What respect is it for you to constantly pass uninvited public judgment on things I do?
corvus wrote:second going to bed so cold that you required so many layers
What, would you prefer me leave the layers off and be even colder? I don't get it, why is it a mistake to dress to keep warm when sleeping? How many people go on a 4 or 5 day walk and take 8 dry layers of clothing? It's about being prepared...

That's just silly! What two person tent can you sit up in beside your companion and not touch the side?
