This place is magical. So many others have depicted Zion in words and pictures, that I won't try to beat them.
This morning we started early in the cool before the strong strong sun came over the canyon walls. We visited weeping rock where water seps out from the rock walls and where natural hanging gardens wow those who look up.
Then we went to the river walk trail at the head of the canyon. This is the most famous place in Zion. It was great. We walked the paved trail one mile to the end. Then, we intended to continue upstream wading in the water. We both had crocs shoes suitable for wading. Poor Libby though, she got only ankle deep when she asked to beg off. We went back to the trail and looked at her feet. They were blue as smurfs! Her core temperature was way down also. Our ambitions are younger than our bodies.
Quickly, I got Libby back to the river bend spot. The warm sun was shining there. I also dressed her in my warm shirt and added my sox to here's, put hope her jacket, and sat her down on a rock heated by the sun. She protested that it wasn't needed, but when she stood up, the rock was cold.
We both envied the younger tourists. They could wade up the ice cld river to the narrow end. They could and did hike up the trails to the canyon rim and peer down at us from 2000 feet above. Getting old sucks in many respects.
We have another 1.5 daya to go at Zion. I'll make sure that we do our activities when it's not so cold.
By the way, I figures out that the cliff face right behind our tent is 3000 feet (1000 m) high.
