There are numerous overlooks along the drive and the view is spectacular
from all of them. Some of the geological formations like the Alluvial
fan are only appreciated when viewed from above.
The landscape changes from forest to alpine tundra along the drive.
The picture on the left was taken at 12,210 feet. Well above timberline
and even in summer can be quite cool.
The glaciers that shaped the granite faces of the rocks were fairly
recent. Only 10,000 to 15,000 years ago during the last major ice
age. About 13,000 years ago, temperature changed and the ice melted,
leaving rocks strewn along the edges and termination of their paths forming
moraines, or ridges of rock debris. A terminal moraine is formed
a the the foot of a glacier, creating a natural dam that creates a lake
from the runoff of the melting glacier.
Remember, do not feed the wildlife. It's important that they remain
a part of the balance of nature by finding and eating their own food.
