Yeti Pearson is a yeti who married The Woodsman after he ran off to plot revenge. Based on Dan's(true given his luck) story, it's assumed the two ran across each other, became friends, fell in love, and married. This is contradicted, however, by the fact he already wore the ring when he was younger(though this could have been his wife's ring which he later gave to his Yeti groom)
He apparently had a long life, as even in 2011 he was still alive and well, defending the same glacial weak point his husband had died at. Despite being well over a hundred years old, he one shot Chris in his bear form with a single blow.
He was last seen in the cave, and was likely consumed in the avalanche
