What can tell the direction in the canal in winter?

If there is no water in the canal, refer to the snow in the canal. In shady places, there will be snow, that is to say, the snow-covered side is south or facing south. If there is no snow, the shady side is wetter, because the snow melts later and is wetter.

If there is water in the canal, refer to the frozen ice near the shore in the canal. The side with ice or chunks of ice is south or south.

To illustrate the problem, no pictures of the canal were found. Just give examples of small ridges, ditches and roofs in the fields.
