About poles and cairns:

Pole marker on an Alpine route <https://en.wikipedia.org/wiki/Alpine_route> at
Piz Uccello, Switzerland

Poles, colored or not, are often used to keep the trail visible during
winter and under snow cover.[6]

Main article: Cairn <https://en.wikipedia.org/wiki/Cairn>
Cairns are carefully arranged piles of stones. Cairns are most commonly
used to indicate trails in open areas, such as higher-elevation alpine areas
<https://en.wikipedia.org/wiki/Alpine_climate>, where no trees are
available, or where conditions may make blazes hard to see.[4]

Doesn't say routes.
