You set off, Jo-owrn leading, down into the valley.
You make poor time. Still leading the horses, you have to fight for every inch of progress through snow over 3' deep. Where it has drifted it is more than twice that depth. All the same, it is downhill, and by late afternoon you have come down out of the mountains and are again on more or less level land. There is dense coniferous forest here, and it shelters you from the constant wind. The temperature struggles up to 10F, but by the time night falls and you set up camp, it has dropped back to close to zero.
The night passes quietly.
