Any photos from the recce?
Anyone has a link to the starting order?
As a natural scientist I must say that you are wrong. This heat related. You know that water melts at 0 degrees and boils at 100 degrees when the pressure is 1 Atmosphere. When you climb up to the high mountains, then you can see that water boils already in 80 degrees and you cannot boil potatoes.Quote:

On the glaciers the ice shield often forms in similar way. Due to the very thick snow layer it compacts due to its own weight and at some point the weight is so high that snow has turned to ice. So, under the wheels of cars similar ice can actually form. But when there is nearly no local traffic and maybe only a few small cars, then recce cars with bit higher speed and bit more aggressive driving style are going to cut through the very thin ice and snow layer. The ice layer is so thin thanks to the fact that snow plough always cleans roads after snowing and there are not enough cars passing the road between the start of snowing and passage of snow plough.
And by the way, Loeb also went into the ditch during the recce.
Haha, I'm immediately taking a step down in favour of your knowledge. Thanks for the explanation. However, I still claim that you can't call the current conditions anything else than true winter conditions :) (And I also doubt more traffic would have changed things significantly... It must take years [ no proof of that but some experience from living in Sweden ] to build a thick solid ice layer with just pressure and snow!?!)Quote:

Some of the roads are not much in daily use, I have read somewhere, and have just recently been cleared. So no cars have had the chance to compress the snow. That is why it just disappear now, it is just powder-snow.
Maybe the organizer should have made sure that the roads had been driven on regularly to create the ice sole ? But we are talking long distances here, but it is not impossible with local volunteers !
whats the fuss guys, the conditions dont differ too much in a seeded entry, this might make it even more interesting, on tarmac rally they very seldom dry the tarmac after rain too.
That's a really good point. All this chat is from a driver point of view. For spectators, it's just extra drama. You'll get your feet snowy, I promise! :DQuote:
