Munich lies on the elevated plains of Upper Bavaria, about 50 km (31.07 mi) north of the northern edge of the Alps, at an altitude of about 520 m (1,706.04 ft) ASL. The local rivers are the Isar and the W�rm. Munich is situated in the Northern Alpine Foreland. The northern part of this sandy plateau includes a highly fertile flint area which is no longer affected by the folding processes found in the Alps, while the southern part is covered with morainic hills. Between these are fields of fluvio-glacial out-wash, such as around Munich. Wherever these deposits get thinner, the ground water can permeate the gravel surface and flood the area, leading to marshes as in the north of Munich.
It is located on the River Isar north of the Bavarian Alps. Munich is the third largest city in Germany, behind Berlin and Hamburg. About 1.42 million people live within the city limits. Munich was the host city of the 1972 Summer Olympics
