Vopnalág (“Weapons hollow”) and Kárahella, (“Kári’s slab”) place names to the east of Reyðarbarmur where the road comes down from Barmaskarð pass. It is said that Kári Sölmundarson in Njáls saga waited there to ambush Flosi and his men when they came from Alþingi in the spring of 1012. Flosi realised they were there and turned north.
