Mt. Togetadke is a dacite peak on the main divide between the upper stream of the Shiroishi River and the Surikani River, in the Ôu Range. Both rivers are the tributaries of the Abukuma River.At the northern foot of the Mt. Togetadake, in the drainage area of the Shiroishi River, gentle slopes are observed. These slopes spread along the valleis from Mt. Toetadake to the river bed of the Shiroishi River. Near Togeta, many slope joined and overspread as a confluent slope, but near Nametsu, slopes are seen as a small slope in each valley. These gentle slopes are seen in this area only along the river.Materials, underlying the gentle slopes, are dacite gravels and sand, and differ from the bed rocks, tuffaceous sand and tuff breccia.Judging from its extent, materials and other conditions, these gentle slopes probably were made by earthflow.
