Dad's Hike in Arches at Park Avenue

Guess I need to post a few pictures of the trip.
This is in Arches, our first stop, where Dad took
his hike.  If you zoom in you can see people
down there.  The hike goes through that hole back there where the single rock is standing.   (I waited at the top for him) I thought he would hike back the same way and meet me at the top but he called me on the cell and said - no, he was going around the rock and to meet him at the next viewpoint.  I actually was getting a little anxious when he didn't come back up the trail.   (miscommunication) I actually had a good time sitting and listening to the ranger guide talk to people.
