Arches National Park is comprised of over 2,000 sandstone arches. Basically, these are rocks that have been eaten away by erosion, leaving an "arch" left. The most famous of the arches is Delicate Arch.
Streams of water used to run through the rocks.
Water used to flow through the area.

Waterways used to run through the arches.
The arches were formed due to wind erosion. The wind picks up sand grains and scours away at the rocks, seeking out weak areas.
It is a vault or vaulted roof. It is formed by a series of vaults/vaulted arches.
it is said that you can lick the roof of its arches because of its texture.

In deserts, arches and mushroom rocks are formed when the sand in sand storms blows it and other materials against the rock which eventually erodes the rock into interesting shapes such as arches. ~Tom1819
Sea stacks are formed when a sea arch collapses and sea arches are formed when waves (pound) erode or ware away a whole in the headland.
The arches at Arches National Park are the result of differential erosion of sandstone between parallel joints or cracks in that sandstone. These particular joints were created when the sandstone layer was undermined by groundwater dissolving the salts out of the underlying layer of rock known to geologists as the Paradox Formation. As the overlying layer of sandstone slowly collapsed into the void created by the dissolving salts, the parallel joints were formed. Later, erosion of the sandstone between the joints created the arches. Even later, someone thought that this would make a good place for a National Park. In short, the arches at Arches National Park exist because the halite of the Paradox Formation was dissolved and removed by groundwater.

I'm not so sure if it's correct, but I think it's an arcade.
I think you're looking for the "Dome".
