Búlandshöfði, a headland descending sheer into the sea, with rock belts at its top and base, and scree in between. Formerly a great obstacle to travel because of its steepness, Þrælaskriða being the most notorious scree. In Búlandshöfði Dr. Helgi Pjeturss (1872–1949) found interesting strata of sea–shells and remains from the Ice Age 135–180 m above sea–level. This is an important contribution to the knowledge of climatic changes during the Ice Age in Iceland. Similar strata have since been found in other mountains nearby, e.g. Stöð, Kirkjufell, Mýrarhyrna.
