This treasure of Arches National Park lies on the popular Devils Garden trail, which is at the very end of the park road (around a 45-minute drive from the visitor center). Landscape Arch holds the distinction as being the fifth longest arch in the world. Do Arches Ever Fall? Short answer: Yes. Sadly, it’s a natural part of an arch’s life, but they don’t fall too often on the grand scale of things (and we help with that by not touching or standing on any of the arches). Erosion from wind and weather removes layers of rock, making changes over time. In 2008 for example, the Wall Arch suddenly collapsed. These types of collapses can be unpredictable which adds to the mystery and beauty of the arches. What Are the Highest and Lowest Elevations of Arches National Park? Arches lowest elevation is at the Colorado River, at 3,960 feet, though the National Park Service notes the Visitor Center as the lowest elevation at 4,085 feet. This could be because the Colorado River is right on the border of the park. The highest point is Elephant Butte, at 5,653 feet. Why are Arches rocks red? The crimson color of the arches is due to iron oxide in the sandstone sediment. Rocks can be all different colors depending on the minerals in them and what the conditions were when forming — was it underwater? Under pressure? With oxygen? Without? The arches here are made from sandstone – Entrada Sandstone in particular. These grains of sand packed together when the whole area was under water, but once out of water, wind and rain has been slowly eroding the stone to create these formations.

We didn’t name this park Arches for nothing; this region has the highest concentration of stone arches anywhere in the world! What is more fascinating than the sheer number of arches is that the trails we use within the park system in Moab were once totally submerged in water. Seawater subsided and left behind sand that the wind formed into dunes. Petrified dunes developed and through long term wind and rain, it formed the landscape we see today. Most of the wildlife within the park is actually nocturnal or crepuscular meaning they are most active at night or at dusk and dawn. This is because Arches is a high desert climate, meaning extremely hot summers and very little precipitation. This also means if you want to see wildlife, you’ll want to be around for either dusk or dawn.
