I love well-behaved spiders! They are, in fact, how most people find my site. Unfortunately, my network has a limited bandwidth and pictures take up bandwidth. Spiders ask for lots and lots of pages and chew up lots and lots of bandwidth which slows things down considerably for regular folk. To counter this, you'll see all the text on the page but the images are being suppressed. Also, some system options like merges are being blocked for you.
Note: Permission is NOT granted for spiders, robots, etc to use the site for AI-generation purposes. I'm sure you're thrilled by your ability to make revenue from my work but there's nothing in that for my human users or for me.
If you are in fact human, please email me at guthrie.bruce@gmail.com and I can check if your designation was made in error. Given your number of hits, that's unlikely but what the hell.

OAK_120720_052.JPG: Canyon Walls Reveal Evidence from Past Landscapes:
In a short drive from the Mogollon Rim down Oak Creek Canyon, one can find evidence of past worlds. Journey to ocean beaches, tidal flats, desert sand dunes, rivers and deltas. These ancient landscapes have been exposed by the carving of Oak Creek and more recent road cuts.
Why do the rocks have dramatic shapes and spires?
Exposure to faulting, water and freezing temperatures over time causes rock to weather into bizarre and interesting shapes. Harder rock erodes slowly, leaving sheer cliffs. Softer rock erodes more rapidly, forming slopes.
Why are some rock formations red?
Sand grains became covered with thin coatings of iron oxide as ground water filtered through the rocks before they were eroded.
Why is the east side of the canyon lower than the west side?
A fault line runs down the middle of Oak Creek Canyon. Movement along the fault has shifted the layers so that the east side of the canyon in as much as 1,000 feet lower than the west side.
How old are these rocks?
The sedimentary rocks in Oak Creek Canyon were deposited over a span of 45 million years, from the late Pennsylvanian through the Permian geologic periods. The most recent sedimentary rock you see here, the Kaibab Formation, is approximately 255 million years old and predates the dinosaurs.
Wikipedia Description: Oak Creek Canyon
From Wikipedia, the free encyclopedia
Oak Creek Canyon is a 12 mile (20 km) long river gorge located along the Mogollon Rim in northern Arizona located between the cities of Flagstaff and Sedona. The canyon is often described as a smaller cousin of the Grand Canyon because of its scenic beauty. State Route 89A enters the canyon on its north end via a series of hairpin turns before traversing the bottom of the canyon for about 13 miles (20.8 kilometers) until the highway enters the town of Sedona. The Oak Creek Canyon-Sedona area is the second most popular tourist destination in Arizona, second only to the Grand Canyon.
Bigger photos? To save server space, the full-sized versions of these images have either not been loaded to the server or have been removed from the server. (Only some pages are loaded with full-sized images and those usually get removed after three months.)
I still have them though. If you want me to email them to you, please send an email to guthrie.bruce@gmail.com
and I can email them to you, or, depending on the number of images, just repost the page again will the full-sized images.
