If the access road hasn't been snowed in by November, and there is snow on the upper mountain, I understand the Clear Creek route is great - and probably the easiest way up the peak. No rope necessary, but if it's icy, crampons might be useful. If your plans are put off until wintertime, the Green Butte/Avalanche Gulch route is the way to go - snow conditions permitting. The actual gulch is fairly steep as you approach Thumb Rock at 12800'. If it's icy, it could be scary for novices. Plowed road to 6800 feet makes it the route of choice though. A great ski too!
