Bowtie Arch

Bowtie Arch, also known as Pinto Arch, is a good example of a pothole arch, where water first eroded a large pothole or water tank atop the sandstone cliff. Additional chemical and mechanical erosion wore through the bottom of the pothole. The result is a hole in the bottom of the pothole. Subsequent erosion, sometimes due to rainstorm runoff, has enlarged this hole creating the arch you see today.

Cool explanation ..

This is WHY I cannot find the "Pothole Arch"
inside Arches National Park.

I've searched for it several different times
throughout the last 30 years, and have not
yet seen it in person.

It is hidden BEHIND part of itself ...
