Over time the canyon grows wider as the decaying exposed rock fractures and weakens due to freeze-thaw and other forces of erosion, finally falling in and heading for the river below. The big rock that's leaning in is safe for now!
This image was shot on film during 2001 at the south rim of the Grand Canyon USA.
That's an impressive shot! Wow. You can see so much detail. It's neat how the light is coming in like that too. I remember that trip and spot! Good memories.
There's so many beautiful views along the south rim, and yes great memories. Thank you.
