Split Decision Kit
Voilé's Split Decision Kit ($150; www.voile-usa.com) is an interesting option. It lets you take an old snowboard, saw it in half lengthwise, and then fix bindings to each side. You can then use them like short cross-country skis to get to your destination, reassemble the snowboard with clip attachments, and board away. Very clever, it saves you from having to carry any extra gear. But I'd say it's best for rolling terrain, rather than anything really steep. For those double-black pitches, the Verts, or a pair of tough, compact snowshoes such as MSR's Lightning Ascent ($250; www.msrcorp.com), are best.
You probably would need to invest in some boots as wellsnowboard boots are generally too flexy to handle steep terrain. The ideal solution is a pair of light plastic boots, such as Koflach Degres ($270; www.koflachusa.com). They're warm enough for winter, keep your feet dry, and have the rigidity needed for steep terrain wearing either Verts or traditional snowshoes.
Be careful out there. It's always better to call it a day than take a chance and get nailed by an avalanche. And unfortunately, today's better backcountry gear is putting more and more people into harm's way.
