Answer:
The loss of the rock arch and the search for it.
Explanation:
The main idea projected by James Vlaho in the essay above was the loss of the rock arch at the Canyonlands National Park and the hunt for it. This is supported by the details of the two men who joined the writer in the search for the lost rock arch. The two men were Tom Budlong and Tom Van Bebber who searched for clues to the lost rock arch. These men were devoted to arch hunting and belonged to the Natural Arch and Bridge Society, an arch-hunting club.
To search for a lost arch, they study the charts on maps and hike a lot of distance. Finally, they succeeded in finding the lost arch.
