This photo is from a place called Vuollerim (a much more detailed description on the Swedish version). It’s situated close where to rivers join, and because of the composition of the soil this is what you get. The river(s) carves out some very steep hills from the ground, in this case I guess it’s around 40 meters high. The slope here is probably around 45 degrees but around 10m from the path it increases to perhaps 60-80 degrees. If you stumble and fall you will either stop when you crash into a tree … or you when fall into the river below.
I’m not from Vuollerim but from another place with similar conditions, so this is how it looks like around where I grew up. We call these steep slopes “nipa”
