If there's a prettier mountain in the world, I don't want to know about it. Here's my hometown mountain, the San Francisco Peaks (Arizona's high point), as seen from the north. The prominent snowfield off the main summit, with its three fingers, is Abineau Canyon—certainly one of the biggest, most aesthetic backcountry ski descents in Arizona.
I'm not sure if Abineau is the most active avalanche path on the mountain, but it is easily the most spectacular, capable of throwing down massive slides. Such nightmarish possibilities have always kept me away during midwinter months, though this remains high on my list of must-do descents (I'm not counting a low-snow tour I did down the summit ridge in late April).
