North of McDonald Creek, you can see Heaven’s Peak, although I think the best picture I got of Heaven’s Peak was taken on Sunday when I was going east-to-west. The sun just wasn’t right for a good picture today. Doesn’t matter though, you can feel the mountain’s presence anyway. I read and learned about aretes, a sharp ridge formed by two separate glaciers carving out valleys and leaving a ridge of mountain in between them. I also learned about hanging valleys, a term I first read in a book by Zane Grey. A smaller glacier cuts a valley and then joins with a larger glacier moving roughly perpendicular to it. The small glacier’s valley stops at the side of the larger glacier’s valley. It’s left hanging. There are many images of hanging valleys.
As you work you way east on the Going To The Sun Road, you are constantly amazed at the work it took to construct the road itself. There are many pictures of the road where you can see how it was notched into the side of the mountain and I read that the road was constructed in the early 1930’s. I also read that Mother Nature doesn’t like guardrails, as the people plowing out the road in the spring and summer would find the guardrails in the valleys, having been ripped off the mountain presumably by avalanches.
There are turnouts where cars can park and see the scenery, but one great advantage of a motorcycle is that I can stop and turn around almost anywhere. I was able to get some pictures that would take a lot of walking if you were going through the park in a car.
