The cave is 10.5 meters wide and 12 meters in length. His highest height is 3.10 meters, he is the tallest to the southeast but decreases greatly to the perimeter. The Thord's Thorn Mine is very low and rather slender, and you have to crawl a rocky shore down to get into the cave. Remnants of loading on the right side when entering the cave will still have been visible at the end of the 19th century and the beginning of the 20th. There is no unnecessary signal of humanity in the cave.

Stories suggest that Þórðarhellir is an old outdoor place. Two stories are written by Thord, to whom the cave is taught. Some believe that he is taught by Thordur Galdramann Guðbrandsson, a farmer at Munaðarnes, burned for magic in 1654. The history says he has escaped the fire and sought the farmer in Litlu-Ávík who has hidden him in the cave.

Another murmur and all the more faithful hermits that the cave draws a name from Thordur sakamanni, who was hidden in the cave for a while. Love took him and the little girl in Litlu-Ávík and moved to the cave to him and gave birth to a child. The farmer of Litau-Ávík reacted viciously when he heard where his daughter went and took a team in the cave and took the girl and the child away. The men returned to Thord, but he got them down from the cliff pillars at Hyrninn and threw them into stones. It was said that the farmer had suffered from the damage he suffered from Thordur.
