Landscape Arch above spans over 100 yards. Photographs fail to render the three dimensional features. Only by hiking up the trail, turning that last corner and wandering around to view from different angles do the arches reveal their true nature. My head was spinning trying to take in the detailed patterns on rock faces, judge the sizes of dramatically shaped features, imagine the geologic timescale and focus on the variety of terrain in every direction at different distances.

The reason there are more arches here than anywhere else in the world is salt. As elsewhere, the land formed in layered deposits, rose up and eroded. The unique part was that there were more layers of salt from shallow inland seas which slowly migrated underground and piled up against a hard fault line, forming an unstable underground salt dome that liquified and caused many long straight vertical cracks in the rock layer above. The exposed fins of sandstone eroded from both sides forming many arches and small windows. (Bridges are entirely different than arches).

In theory, the most famous arches are easily explored. Only a few miles from Moab, the main park road climbs up through the dramatic red canyon and branches off towards Delicate Arch above a salty valley, past Balanced Rock towards the Windows and up above to the Devil’s Garden. Each area has parking, and many of the trails are easy. In March, there were only a few visitors in the morning, and every arch waited patiently for me to admire. But by April the park requires timed reservations due to crowds, and in summer the heat can become dangerous. So in practice, you should time your visit thoughtfully, especially if you want to capture sunrise or sunset views without crowds.
