The mountain- chain on Reykjanes is broad and flat at the top; it is divided into several smaller plateaus (800—600 metres) with rows of craters and volcanic mountain-tops, and it sinks down more and more towards the west so that the extreme end of the peninsula consists chiefly of low-lying lava-fields with a few low, isolated mountain- tops. The mountain-chain which extends toward Snaefellsnes is higher (600—900 metres), but much narrower; it is also very vol-

In North Iceland several great mountain-masses proceed from the high land outward upon the peninsulas, and from the head of the fjords long valleys extend into the country; by the extensive branching of the valleys, the mountains are divided into a number of ridges and peaks, which however when examined more closely, prove to have been cut out of an originally continuous plateau. Several valleys lead up from Hunafloi, of which the western are narrow, but the eastern (Vi5idalur, Vatnsdalur, Blondudalur) are broader and more fertile; these latter open out toward the low land (Thing) at the head of Hunafloi.
