hi there
This link is a bit screwed up but gives the waypoints for the intersections for the route you were asking about.
http://bike.stu.ph/rides/ride.php?ride=174
import it into google Earth and it gets a bit easier to use, Mapsource too.
the snow will be off in late june, last year i got to beaverdam on the yalakom in early may but the snowclearing was the mine activity at Blue creek.
Typicaly the snow is off by mid june.
I think i posted the route explanation on this site a bunch of years ago... have no idea where it is now.
