This has nothing to do with the OP'S questions as I have never ridden in the Snowies, but I took a trip out to Revelstoke back in 1992 in mid April, we had heard of all the snow out there and made reservations at a place called Peaks Lodge, they told us they ride into early July most years so come on out. We drove the 18 hours to get there plus we had some trouble at the border so we pulled into town late morning, the grass was green, the trees had leaves on them. We saw people towing boats around town. We checked in and asked where the snow was. They told us to go up this gravel road to km marker 4 and we could park there, unload, and ride from there. We drove there and there was a couple of vehicles with trailers but no snow, only gravel and small rocks. Right after we got there a couple of guys pull up on sleds and we asked them where the snow was. They said to unload and ride up the gravel and after the first curve we would run into snow. They were right and we had a great 4 days of riding but were nervous at first.
