Temporary Lakes

By looking at flood sediments from Glacial Lake Missoula, geologists try to calculate the number floods and subsequent fillings of the glacial lake. Many layers of glacial lake sediments are found situated on top of one another; each layer represents a separate filling of the lake. The exact number of floods that occurred is still unknown, but evidence shows that it happened on possibly 40 different occasions.
