I have to give you cudos for this image!

I actually don't know how far you are from the alligator babies, but I'm just thinking that Alligator Mom is probably very close, and I'm betting that she don't want anything close to her babies😁
So big respect to you @stillcrazyman!

I joined a double exposure group this year. I doubt I'll be able to manage creating one every week, but there is a lot of insane talent in this particular group that I am excited to learn from and be inspired by. I started off easy this week by creating mine in Photoshop with two different film images; one a weird accidental light leak kind of thing and the the other of the dogwood.

Fun to create something un-created before.

One of my favorite roadcuts/rest area stops is in the Dragoons in Arizona. Here is a shot from one of my trips.

Granitic boulders of the Dragoon Mountains exposed on I-10 west of Benson, Arizona. The knobby appearance of the rock results from resistance to chemical weathering by orthoclase (K-Spar) and quartz minerals.

These Early Tertiary to Late Cretaceous Granitic Rocks (50-82 Ma) are porphyritic to equigranular granite emplaced during the Laramide orogeny. Larger plutons are characteristically medium-grained, biotite +/- hornblende granodiorite to granite. Smaller, shallow-level intrusions are typically porphyritic. Most of the large copper deposits in Arizona are associated with porphyritic granitic rocks of this unit, and are thus named 'porphyry copper deposits'.

Here is a good link with more photos for those interested in learning more about my favorite stop on way to Tucson:

I stopped at this very rest area back in 2001!

I have been going to the annual big Rock, Mineral and Fossil Show in Tucson now for 16 years. It is our first stop in crossing into Arizona on I-10, and often on way back. Great rest area with beautiful scenery as you found out. I have tons of photos taken over the years.

Beautiful photo, but I must admit that your explanation/description went right

So a slightly sad story with the next few images from Glacier National Park. This one is a non-cliche early morning image of St. Mary's Lake.

I returned in October of 1975 with my own Linhof Technika 4x5 press camera and it's 127mm Schneider Xenar lens. I was also using the then new to the market Vericolor-II type-S film. This film mainly featured less silver, thinner emulsion layers and was supposedly more permanent. However there was a catch to that last one. The developer tended to have a high evaporation rate and labs really needed to keep track of specific gravity or the developer would become more alkaline and the carryover would weaken the following step the bleach. Also the published replenishment rate for the bleach step presumed the film was squeegeed after the developer to reduce carry-over. For the dip and dunk process used for 4x5, the bleach replenishment needed to be at least 25% higher than spec. Once the developer has done it's magic coupling exposed silvers to the dyes in that particular layer, the bleach then converts the exposed portion of the silver back to unexposed, all of the silver is then removed in the fix step which follows the bleach.

In the case of these negs the bleach was weak and all of the silver was not removed. They printed just fine at the time but after 47+ years that retained silver has created a base fog and some processing streaks. For the most part I have been able to clean them up in PhotoShop, but they are still damaged. If I had access to a C-41 dip and dunk process I could just run these back through the bleach and fix steps and perhaps remove some of the base fogging.

Schneider Xenar 127mm lens, ƒ-19, 1/25sec. Process damaged V-II film. Scanned @1200ppi.

Well basically they are weathered granite in simple terms. I am a retired geologist so a rock nerd LOL
Thank you! That was simple enough for me.😊 I was not trying to be disrespectful in any way. If anything, I was embarrassed having to admit my ignorance of geology and missing most of what you said in your description. I actually love rocks and gems. Over the years of going to the NC and TN mountains, my son would always bring back a sack of rocks and gemstones from the gift shops and tourist mines. Each year he would give me one of his rocks, and I always put them in a sack that I carry in my pocket for good luck. The coin is a 1925 D Wheatback penny I found on the ground in a parking lot.
