Kinnekulle is a flat-topped mountain in the county of Västergötland, southwestern Sweden, on the eastern shore of lake Vänern. Its highest point is 306 m (1,004 ft) above sea level. The mountain is 14 km (8.7 mi) long and 7 km (4.3 mi) wide at the top. Geology. Despite its enormous size, Kinnekulle is actually the smaller remnant of a much larger plateau, long ago worn down to a flat plain. Some 550 million years ago, in the Neoproterozoic Era, the bottom-most rock of the plateau was under the sea. Layers of sedimentary rock formed over that layer from sand, mud, and sea animal remains.
