Interstratal karst is a karstic landscape which is developed beneath a cover of insoluble rocks. Cem passes mostly through limestone terrain where many karstic formations are observed. Ofra lies in a karstic region, with several stalactite caves and dolines. The lakes of the country are predominantly of karstic or glacial origin. The plain is a closed geological basin of karstic origin. Scholar's stones are generally karstic limestone. The lime rocks have been weathered into characteristic karstic rock formations known as rauks. The ruins lie upon a poorly drained karstic plateau. In the massif's karstic area is the Vercors Cave System and the Gouffre Berger. In some areas, the subsoil is karstic. The surface was formed mostly by karstic erosions. It is a nonmigratory fish which lives in streams and in karstic resurgences. The path passes through areas of different vegetation and through many different karstic features. They are mostly found preserved in karstic deposits. It is found up to above sea level and often occurs in karstic areas.
