I guess you actually know it but said wrong word in the video, you said "Moose" @ ~22:42, but it's "Reindeer", and the "Reindeer hut" got it's name because it was used by Laplanders to live with Raindeers a long time ago when they actually lived among them.
@@levb.7338 I watched several times more, and you might be right, it's really hard to see on the video, and since they where so small it looked like reindeers but it might be a small cow with her calf. Moose is very common sight in north of Sweden so it's not like you saw a Bear, a Wolverine or a Lynx ;) I've seen Bear with cubs a couple of times and Wolverine once in the wild, but never a Lynx.
Be careful with the delicate nature of the Swedisch fjäll when walking through bushes. Tourism's impact on nature is a severe strain on the fragile ecosystem.
