There is a difference between a window, an arch and a bridge. All of these terms are used to designate holes in cliffs and rocks. A window is a naturally forming hole through a narrow rock ridge. This picture shows a famous window on the North Rim of the Grand Canyon called Angel's Window. You might have to click on the photo to see it clearly. The window is actually quite large, but the size of the Canyon makes everything look small from a distance.
An arch is a free standing window. The most famous arch is Delicate Arch in Arches National Park in Utah. A bridge is an arch that is over a watercourse. There are a large number of examples in Bridges National Monument in Utah. Whether the feature is a window, an arch or a bridge, they are fascinating natural features.
I am always impressed by the names of the mountains and other points. They imply the reasons for their names.
