A bit further north we find this: https://www.google.com/maps/place/68%C2%B022'37.0%22N+20%C2%B055'10.9%22Eemail@example.com,21.0819801,622m/data=!3m1!1e3!4m2!3m1!1s0x0:0x0
I scouted around a bit and found more solitary white circles, and more green-brown clusters, and in every case, roads go to them. (I just realized, I'm assuming those are roads, but it's possible they are caribou/reindeer trails. Leads to interesting thoughts.)
Anyone know what these things are? They don't stand up from the surface much, they are flat. There are villages in the vicinity, but at a (safe?) distance from the spots, and roads go to the spots. I'm not sure they're villages, either - they're widely scattered houses along the roads.
