"Bjorn boarded a skiff he owned, taking his household and goods with him, and sailed south along the coast of Norway. ...He sailed until he came to the island of Moster, which lies off of southern Hordaland, and there was received by a man named Hrolf.

"..Hrolf was a prominent chieftain and a man of great largesse. He maintained a temple to Thor on the island and was a great friend of Thor's. It was because of this that he was known as Thorolf. He was a big man and handsome and strong and he sported a huge beard, which led to him being nicknamed Moster-beard.

"...Thorolf Moster-beard held a great sacrifical feast during which he consulted his dear friend Thor about whether he should reconcile himself with the king or leave the country and seek another fate. The oracle directed Thorolf to Iceland. He got himself an ocean-going ship and prepared it for the journey to Iceland, taking with him his household and all his goods. Many of his friends decided to go on the journey with him. He dismantled the temple and transported most of its timbers, together with earth from underneath the pedestal on which Thor had been placed.

"...Thorolf then sailed out to sea with a fair wind and came within sight of land sailing then west along the southern coast and around cape Reykjanes. The wind dropped and they could see on the shore where broad fjords cut into the land. Thorolf cast overboard the high-seat pillars which had been in his temple, one of which had Thor carved on it. Thorolf declared that he would settle in Iceland in whatever place Thor directed the pillars to land. As soon as the pillars were thrown overboard, they were swept towards the more westerly of the fjords and seemed to travel faster than might be expected.

"...He put in to land halfway along the southern shore of  the fjord and anchored his ship in a cove there, which has since been named Hofsvog. After that they explored the area and found that Thor and the pillars were already ashore at the tip of the headland north of the cove. The headland has been called Thorsnes ever since.
 
"..Then Thorolf carried fire around his land-claim, from the Stafa river as far as the river he named Thorsa (Thor's river). He established settlements for his crew and set up a large farm by the cove, Hofsvog, which he called Hofstadir. There he had a temple built and it was a sizeable building, with a door on the side-wall near the gable. The high-seat pillars were placed inside the door, and nails, that were called holy nails were driven into them. Beyond that point, the temple was a sanctuary. At the inner end there was a structure similar to the choir in churches nowadays and there was a raised platform in the middle of the floor like an altar, where a ring weighing twenty ounces and fashioned without a join was placed, and all oaths had to be sworn on this ring. It also had to be worn by the temple priest at all public gatherings. A sacrificial bowl was placed on the platform and in it a sacrificial twig — like a priest's aspergillum — which was used to sprinkle blood from the bowl. This blood, which was called sacrificial blood, was the blood of live animals offered to the gods. The gods were placed around the platform in the choir-like structure within the temple. All the farmers had to pay a toll to the temple and they were obliged to supoport the temple goði in all his campaigns, just as thingmen are now obliged to do for their chieftain. The temple goði was responsible for the upkeep of the temple and ensuring it was maintained properly, as well as for holding sacrificial feasts in it."  (Translated by Judy Quinn, The Complete Sagas of the Icelanders, Vol. V. ) 

Because the findings fit so well together with the Norse sources, the sources are likely more reliable than many scientists now believe.
