10 Interesting Facts About Arches National Park
1. The Park Was Once an Ocean Floor
Millions of years ago, this region was covered by a shallow sea. Layers of sediment eventually became the rock formations we see today.
2. It’s Built on a Salt Bed
A thick layer of underground salt helped shape the landscape. The salt shifted over time, causing the rock above to crack and form arches.
3. Arches Is Younger Than You Think
Though the rocks are ancient, Arches became a national park only in 1971. It was first declared a national monument in 1929.
4. It Covers 76,000+ Acres
Arches National Park spans 76,679 acres—about the size of Washington, D.C. ten times over.
5. Erosion Happens Fast (Geologically Speaking)
While it takes thousands of years to form arches, erosion can also destroy them quickly. A single rainstorm can alter rock shapes significantly.
6. Desert Varnish Darkens the Rocks
Many rock surfaces are coated with desert varnish, a black or reddish sheen made of clay, manganese, and bacteria.
7. It’s Home to Fragile Living Soil
The desert floor hosts biological soil crust, a living layer made of moss, lichen, and cyanobacteria that stabilizes the soil and helps prevent erosion.
8. Balanced Rock Could Fall at Any Time
The massive Balanced Rock looks like it’s defying gravity. It’s stable for now, but someday—maybe tomorrow, maybe in 100 years—it’ll topple.
9. Native Peoples Lived Here for Thousands of Years
The area was once home to Ancestral Puebloans and later Ute and Paiute tribes, whose presence is still honored in the region today.
10. Extreme Temperatures Are Normal
Temperatures can swing from 100°F (38°C) during the day to below freezing at night, especially in spring and fall. Be prepared!
