In reply to MattWarner:
Orion Direct needs a reasonable period of build up to be reasonable, so these days I'd be surprised in early January. For ice mid-mountain can be best at this time - higher and the moisture is not liquid to condense and seep, lower is too warm.
Go with an open mind. At one time I'd say you'll get something done, whereas nowadays I'd say you'll most possibly get something done.
In thin conditions aim for drainage lines, or, if lean and cold go for turfy routes.
