Han tells Luke that he's sticking him in the Tauntaun to keep him warm until he can build the shelter. I figure the mound of snow we see in front of the beacon is the tent that was snowed over during the night. There's a whole scene that takes place inside the shelter in the radio play.
That's interesting. I need to listen to the radio drama of ESB. I've only listened to ANH (three times through).
