Geology
The Alpine Lakes Wilderness features some of the most rugged topography in the
Geological events occurring many years ago created the diverse topography and drastic elevation changes over the Cascade Range leading to various climate differences.The history of the formation of the Cascade Mountains dates back millions of years ago to the late Eocene Epoch.[4] With the North American Plate overriding the Pacific Plate, episodes of volcanic igneous activity persisted.[4] Glacier Peak, a stratovolcano that is 33.5 mi (53.9 km) north of Terrace Mountain, began forming in the mid-Pleistocene. During the Pleistocene period dating back over two million years ago, glaciation advancing and retreating repeatedly scoured and shaped the landscape.[4] The last glacial retreat in the Alpine Lakes area began about 14,000 years ago and was north of the Canada–US border by 10,000 years ago.[4] The U-shaped cross section of the river valleys is a result of that 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 Alpine Lakes Wilderness area.
