Could these be the shadows of one or more dog sleds following old tracks through the snow on Svalbard, the northernmost part of Norway?

Unfortunately these are only medium resolution images¹ (which disappear in Google Maps if you get too close), but zooming right in on Google Earth certainly seems to add weight to the theory.

Perhaps they’re travelling from the nearby EISCAT radar station to the nearest town - the administrative centre of Svalbard, Longyearbyen?

Actually Longyearbyen is interesting too, as it’s the world’s northernmost town² and therefore has the world’s northernmost of quite a few things, including the world’s most northern bank, ATM, hospital, library, night club, bus station, taxi rank, tourist office, supermarket, school and not not forgetting pub!

Oh yeah, they’ve also got the world’s most northern permanent airport with scheduled flights - Svalbard Airport.

See Wikipedia for more on dog sleds, Longyearbyen, Svalbard and the world’s most northern things.
