Like Muir, those of us who stand along the rim are prompted to wonder about the unearthliness and the forces that created and are still changing this place.
After more than 100 years of studies, many things are still obscure. Today visitors come by the thousands-the great and simple of the earth-all in a spirit of marvel. Travellers come from every state of the Union, from every country in Europe and Asia, pilgrims to a shrine that is the same as the creed. '
From the depths of the canyon comes welling silence. Seldom can you hear the rear of the river. You cannot catch the patter. Like applause, from the leaves of the cottonwoods on the shelflike plateau below you. For all sounds are swallowed in this gulf of space. "It makes one want to murmur. "A woman once whispered to her companion. This silence is not the silence of death; rather, it is a presence. It is like a great piece of music. But music made of man works up to a climax and ceases; the Grand Canyon is all climax, a chord echoing into eternity.
Perhaps the most spectacular feature of the Grand Canyon, its Redwall limestone cliff, stands about half way up the chasm and is practically vertical. Its average height is 550 feet—almost exactly that of the Washington Monument. Though it is actually gray-blue limestone, the surface of the cliff has been stained to a sunset hue by iron salts washing out of the rocks. Above the Redwall come alternating layers of red sandstone and shale 1,000 feet thick, then comes the next pale-blue layer. The topmost layers are a yellowish limestone.
Now, visitors to the South Rim alone may number 18, 000 in a single day. Some of that number will travel by mule train down Bright Angel Trail to the canyon's floor, cross the raging river by a suspension bridge and amount to the North Rim.
Though the two rims face each other across only 12 miles, it is a journey of 214 miles by car from one to the other. Nor can you visit the North Rim except in summer; some 1,200 feet higher than the South Rim ,'it is snow covered much of the year except in July and August.
But there is no day that you may not visit the South Rim and find the sun warm on your face and the air perfumed with the incense of smoke from an Indian hearth. The Grand Canyon is an unearthly sight. No wonder an American writer and journalist said, "I came here an atheist, and departed a devout believer."

M: Oh, hardly, but we had a good time just the same. We managed to stop at the old Ghost Town near Virginia City. That's what Jimmy was all excited about.
W: Did you go to Denver like your wife wanted to？
M: Yes, we stayed with her cousin for two days. We had to pass up the Grand Canyon though, because Jimmy got sick from eating too many grapes.
W: How about the stop at Indian Falls？ Did you have any time for that？
M: Yes, but we almost didn't. We left Denver on Highway 14 when we should have taken Highway 90. When we realized it, it was almost dark. Still we got there in time to take a few pictures.
W: Where else did you go？
M: Well, we went through Phoenix, Arizona. We all liked that. But we had some trouble with the car there. We had to stay an extra day because of that.
W: I bet that made you mad.
M: It sure did, especially because I had the guy at the garage give the car a checkup just before we left home, and he said the car was in excellent condition. Still I can't complain. I was able to get in some extra fishing because of the delay. I went out with the man who was staying in the hotel we were at.
W: Generally, you did quite a lot.
M: Yes, we certainly did. But after we got home, it took us two days to rest up. All that driving around was murder.
