Back in the ‘70s, I spent a number of winters in the North Peace country of B.C. Every winter there would be two or three weeks of those conditions, and it could be brutal with any sort of a wind.
Surprisingly, the coldest temperature is hit right around sunrise - 8:30 or 9:00 A.M.
I recall getting up to build a fire at 6:00, noting that the thermometer read -38, then checking the temperature after breakfast only to discover it was dropping, often to -50C. That is cold - too cold to do anything but feed and water the stock.
It was austerely beautiful.
Now I live in the banana belt of southern interior B.C., currently at 19F with two feet of snow. Life is good.
One of my uncles used to run a fishing/hunting lodge on a lake in southern interior B.C. He had lots of weather and wildlife stories, as well as stories about stupid city people at his lodge.
He ran a crop dusting service in E. Oregon before moving to the lodge, so he was able to fly clients into remote lakes.
