The history of the formation of the Cascade Mountains dates back millions of years ago to the late
During the Pleistocene period dating back over two million years ago, glaciation advancing and retreating repeatedly scoured and shaped the landscape.[5] A small glacial remnant lies on the south slope of Dorado Needle, whereas the northern slope maintains the extensive McAllister Glacier. The U-shaped cross section of the river valleys is a result of recent glaciation. Uplift and faulting in combination with glaciation have been the dominant processes which have created the tall peaks and deep valleys of the North Cascades area.
