Jillian read about Arches National Park in a travel brochure.

A large arch made of stone.

Delicate Arch is a sixty-five-foot-tall freestanding arch found in Moab, Utah. It was originally a large sandstone wall that eroded away over time with water and wind. Delicate Arch is one of Utah’s most well-known landmarks. It is depicted on Utah’s license plate. The Olympic torch relay for the 2002 Winter Olympics ran through the arch. Before it was named Delicate Arch, this landform was called "Cowboy Chaps" by local ranchers.

After reading this text and looking at the picture, which new idea can Jillian form about Delicate Arch?
