The arches are made from sandstone. This was as close as I got. Most of them are far, or a hike, or are not accessible. It was very cold; we didn’t hike. It’s fascinating to read how the arches formed. This one was off road and behind a large sandstone formation. Someone explored and found it a long time ago. Thanks. We stuck to the short trail and got to see it. This has been on my bucket list of pictures. It’s not “the picture.” I’ve been there now. Time was short. It always seems that way. But, I got to see it, experience it, and share it with someone I love. Perfect.
