This is only about an hour from us. Nice place.

Some cross bedding from a time when the interior southwest was like the Sahara.

Ripples probably generated by a rare heavy rain in the distant past.

I don't think of Florida as having much outcropping geology, so I was surprised to see the rocks in the first image down in the vicinity of the Treasure Coast, and during a visit to the Keys a limestone quarry with corals all over the cut wall.
There's actually a cliff, of sorts, along the bay just south of downtown Miami, locally known as "Silver Bluff". Neat thing, but not a part of town I get to on any regular basis. Will share it if I ever do get over there. I think it's part of the core of an old reef. But the quarries in the Keys, yes, they are (were) cutting "keystone", a softish limestone very thick with fossil corals and such. Beautiful stone, but I think authorities have shut down most of the quarries now, to protect the stone. My boss has thousands of square feet of keystone masonry, including patio pavers, column and wall sheathing, etc. around his house.

Good! My original photos were removed from the host site and I had to add new addresses. Because the original post in this thread was as old as it is, I was not able to correct the links myself, but Adam did it for me.

I was about to offer to help when I saw that He had hooked you up. Nice photos. The black and white with reflections is very powerful.

WPRESTO showed some good examples of cross-bedded dune sands, along with a nice slab of ripple marks which I cannot tell if they're eolian or formed under water. To continue with his theme, here are some x-bedded sands near an overlook of the Glen Canyon Dam holding back Lake Powell. The top image the Colorado River is just off to the left and about 400 feet below.

Pretty sure the ripples are sheet wash, but I am emphatically not a sedimentologist.
Some interesting erosional potholes in a "wash." Some of them look as though they were dug by an animal, but SFAIK, not so.

I'm not a sedimentologist -- fluvial geomorphology comes as close as I can -- but the sedimentary formations you folks are showing are terrific. So how about some fossils in the making? These are from autumn leaves becoming embedded in sediment...

A couple of images from along Highway 40 in the Kananaskis Country of Southern Alberta, heading toward the Highwood Pass. These were shot on film with an Espio 105WR in March of 2006, scanned at the lab when developed, possibly the last roll of film I shot before going digital.

Rainbow Bridge, Lake Powell, Utah
Getting here necessitates a 4 hour boat ride up Lake Powell along with a near 1-mile hike up a canyon. This region is overwhelmed with scenery...

Southern Utah is definitely a car-filling place - 32GB per day.
The boulders below are Mojave Desert, southern California.
