"\u00D8stmarka is a forested area to the east of Oslo and part of the congregation of woodland areas known as Oslomarka. The area is situated within the municipalities Oslo, L\u00F8renskog, R\u00E6lingen, Ski and Enebakk. \u00D8stmarka is delimited to the west by populated areas of Oslo, to the north of communities of Sk\u00E5rer, L\u00F8renskog and R\u00E6lingen and to the east by the lake \u00D8yeren, to the south-east lies Enebakk and to the south-west , another forested area. The change from \u00D8stmarka to S\u00F8rmarka takes place at the lake . \u00D8stmarka is marked by its location on top of basement rock (more than 1 billion years old) containing easy-to-see folds that make up valleys and hills in the north-south direction. For this reason the terrain has a lot of hills, no matter where one goes. Along the upper marine border (about 210 meters) the ice of the last ice age has left large amounts of gravel and sand. Sand, Sandbakken (\"Sandy Hill\"), Sandbekken (\"Sandy Creek\") and Grusbakken (\"Gravel Hill\") are all on about the same elevation. The sand mines at \u00D8deg\u00E5rden have been left there by the ice. Beach snails have been found at Lutvann at an elevation of 200 meters."@en . . . .
