It was originally thought that a “moraine” – debris deposited by a receding glacier created the “dam” that created Moraine Lake, near Lake Louise, Alberta but it is now believed that the formation was a result of a rock slide. None the less, the descriptive name was given to the lake in 1899 by W.D. Wilcox.
The lake is located in what is called the “Valley of the Ten Peaks”. That name was given by S.E.S Allen in 1895 to what had previously been known as “Desolation Valley”. The term “Ten Peaks” refer to the 10 mountain peaks that surround this valley.
