The Western Grand Staircase

Inchworm Arch

Inchworm Arch is an appropriately named arch about ten road miles from Johnson Canyon Road. The arch has two openings and is best photographed near sunrise. Near the winter solstice first light should be just after dawn, during the rest of the year it will take some time for the sun to rise above a nearby rock formation to the east.

Getting There

The Flag Point Track Site can be accessed by a 4x4 road starting at the Nephi Pasture Staging Area off Johnson Canyon Road. The map below shows the drive from Johnson Canyon Road. While a 4x4 is needed the drive is relatively easy.

Following the drive to the trailhead there is a short hike of about .2 miles. The well defined trail starts at the south end of the parking area.

Here is an overview map showing the route to Inchworm Arch:

The Flag Point Dinosaur Track Site and Pictographs

Since rock art sites are sometimes vandalized I have decided not to publish the exact location and directions to the tracks and pictographs at this time. I am willing to send you directions if you provide me with your email address and agree not to publish the location of the tracks on the web. Your email address will not be shared with others or used for marketing purposes. In the event of vandalism at the site it may be shared with US or local law enforcement. A request form for directions can be found here.

If you are going to visit the tracksite keep the following in mind:

  • Rock images, potsherds or any artifacts are important traces of the past. Removal or desecration is illegal. Never camp in alcoves or cultural sites. If you witness cultural theft or vandalism, call the crime hotline at 1-800-227-7286. A minimum $250.00 reward is offered for information leading to the arrest and conviction of any person violating cultural resource laws.
  • Keep the stories in place. Collection of rocks, bones or fossils is illegal within the Monument except for antlers or horns as provided for under UDWR regulations.
  • Graffiti on any rock surface offends, vandalizes and is illegal.


The Great Chamber

The Great Chamber contains easily damaged rock fins and will not support extensive visitation so I have decided not to publish its location at this time. Action Photo Tours, with whom I have no relationship, runs tours to the Great Chamber.
