= Grand Canyon Trip! = = Karen and Alison = = = = We're on our way! = = = = This is Bright Angel Trail from a look out point! = = That was our guide. He was standing on the start of a trail into the canyon. This was the Kiabab Limestone on the path. It's at the top layer of the canyon. The bottom layer is Schist. There was coral in the rock! This spot used to be at the bottom of the sea! That's a mule trail. Mr. Kolb used to take pictures of people going down there on mules. Then he would hike 6 miles to water to process them and he would get back before you did! This was a hole in the side of the tunnel. It was used to move rocks out of the tunnel when they were digging it. We had to wear our hard hats in case of falling rocks on the way to the river float. That was our boat driver. Her name was Jodie! It's the Glen Canyon Dam! Lake Powell is on the other side! That was the tunnel hole from the outside! = = = = = = Telephone Poles in the Glen Canyon?! = = = = How would you hike here? Apparently this is a popular hiking spot called the Ropes because near by there were ropes to help you get down. =

= This waterfall was made by small streams that we couldn't see! = = = = = = The sun looked cool from the bottom of a canyon! = 
 * Antelope! The antelope were made much later than the big horn sheep down below!**
 * This rock was called Finger Rock because it looks similar to a finger.**


 * The black stains on the rocks is called Desert Varnish! It is caused by bacteria called Lichens. Lichens can only survive on dry, sun baked rocks and boulders.**
 * This was near the end of our river float. It is the straightest stretch in the Glen Canyon and it is about 2 miles long. They almost decided to put the Hoover Dam here!**

Wow, those people look tiny next to the building. This is where tribal leaders would meet. This is a natural sound amplifier. We could hear them like they were right next to us!** This rock is called Ah Ah. There's another type of rock called Pahoehoe. Ah Ah is sharp, jagged rock and Pahoehoe is smooth rock. Our guide told us we would say Ah Ah if we fell on the Ah Ah rock! **
 * This is a building at Wupatki National Monument. It's still standing after 900 years!
 * This was Sunset Crater. It's called Sunset Crater because the rock on top makes it look like a sunset. It was named by John Wesley Powell. **
 * There's another view of the crater. We took a short hike and we were so close to the crater. The black stuff on the ground is ash. It was there from an eruption over 900 years ago!
