Columnar Joints and Landscapes

Hinomisaki

Hinomisaki is located on the coast in the westernmost of Shimane Peninsula. Columnar joints developed in Neogene rhyolite and formed fine columns, the width of which is several centimeters. The very narrow columns are thought to result from rapid cooling in the sea because the rhyolitic lava spouted out from a submarine volcano. The cross sections represent distorted polygons. The landscape including fine columns and landforms subjected to long-term erosion makes a gentle impression unlike those of Tsumekizaki and the Jogasaki Coast.
