Natural Monument - Traces of the Ice Age

Traces of the Ice Age Bild 110

'Lucerne Sandstone' forms the bedrock of the Glacier Garden. This hump was formed by glacier abrasion during the last ice age and features typical characteristics. Glacial polish, glacial striation, deep glacial potholes and erratic blocks from alpine Central Switzerland document that Lucerne was mainly covered by the 'Reuss' glacier during the Ice Age.
