I believe you there are two groups .Some winter up high on the wind blown south slopes.and in the tree pockets .Keeping in mind they can move up or down as they desire .I saw bucks rutting down at lower elevations that i saw earlier in the year in the alpine over 30 kms away .The low snow pack last year in point ,friends that sled in the alpine noted a lot more deer wintering up high on the wind blown slopes .
