Though the plot of the 1982 film was pretty clear that the Norwegians dug up an alien space craft, and a smaller "human sized" dig that was presumed to be its occupant.
Yes...they do go to the Norwegian base, and find the remains of the alien that the Norwegians had burned, the cut-out slab of ice, and the spaceship. While some of both movies didn't age very well, I still like both of them and watch them in sequence every now and then.
