Unable to answer "What’s the surface here?" – Path – https://osm.org/way/377899299 via StreetComplete 57.3:

There are a lot of changes in the composition of the ground. From deeply embedded stones to an alternance of mud and dirt with a bit of stones and finishing in a regular dirt path. I'm new to this so I'm not sure how to save that. I took pictures, all facing west for anyone who wants to specify exactly what is what.
