Activity One - Explain

This fantastic landscape was not just formed by the movement of water but also by the movement of ice. The last ice age ended in Yosemite approximately 1 million years ago. That glacial period is called the Sherwin and it produced the largest and longest valley glaciers. The youtube clip below shows you the tremendous power a glacier has.
