This video is not instructive. It’s just me digging a path through the snow from our back door to the hives in the backyard that are half buried in snow.
I cleared the lower front entrances afterwards, scraping ice away easily with my hive tool. A few guard bees came out and died from the cold immediately, but at least the colonies are still alive. I continue to be totally in awe of the bees. (See Hives in Snow for more photos.)
