These formations are in an area called the Rock Pinnacles.
This is another of the Rock Pinnacles.
This rock column, one of the Pinnacles, was pretty close to the road.
I headed for the northern end of the main road, to see the area known as Devils Garden. There are several arches that may be reached from the trailhead via an easy well-maintained trail. One similarly easy branch trail leads to a place for viewing Tunnel Arch.
Another easy branch trail leads to Pine Tree Arch, which, if you step carefully, you can go right under.
There's more to come in Part 2. If you wish to review my first visit to Arches N.P., click on "2013" in the Blog Archive and then on "August".
