Went to the Butte to do a sunny winter run but since the road and upper mountain had snow, I just started climbing up the downhill. If conditions worsend, I could turn around and enjoy the downhill. The weather front held off, and blue sky came out, but when I reached the Butte road to the Summit, I had to turn around at 2100' due to melt freeze ice under a snowy dusting. There was no traction. It ended up being an out and back but the views were still great. You could make this lower third loop pictured as your winter season Butte loop. GPS Track and pictures here. The yellow line in the image is a good fire road with some up and down during the traverse.
