 They reached the north-westernmost mountain Eiðiskollur (see map), and the giant stayed in the sea while the witch climbed up the mountain with a heavy rope to tie the islands together so that she could push them onto the giant's back.However, when she attached the rope to the mountain and pulled, the northern part of the mountain split.Further attempts were also unsuccessful, and they struggled through the night, but the base of the mountain was firm and they could not move it.
