Have a look at this: Terracirca
these two people have travelled the way you want 2 years ago now but the pics in the Yakutsk-Magadan section give good idea of what to expect. everything is in german though, so if only pictures are of interst to you, you have to cllck on "reiseberichte" tab, then go in the different parts (Teil 5 is the one you want) in the left hand menu, then click on the "zur Galerie" link.
Hope this helps!! If you go this route, I'll be mostly happy to hear from you, I'm planning this as well, but in a good old 2cv... by the way, 2cvfred, is there a link?
In any case, my email is sebno2[banane]gmail.com, replacing the [banane] with an @...
En français, plutôt, si jamais! Cheers, Seb
Normal cars go to paradise, 2CV's go everywhere!
