I am unsure what this is called, but I find it all over the area.

Great photos! This looks like chalcedony, AKA one of many varieties of microcrystalline quartz/"siliceous ooze".

Can you share your technique/setup? I've been meaning to photograph my collection and was considering LiveComp to achieve even "scientific" lighting.

The quartz / siliceous ooze sounds correct. I often find this in cliffs and exposed outcroppings.

I think all of the photos posted here so far were taken with the Olympus 60 mm and EM1 II, using in camera focus stacking. I have a 24" light cube that I used along with a Benro tripod. I have various lights that I used, because it seems every subject needed something different. I will try to reassemble everything and take some photos of the set up.

That would be great, thank you! I really appreciate it. Maybe one day this week I'll get around to attempting a few rock portraits, something to do while working from home!

An agate streak and some revealed structures on the cleavage face of a parking lot boundary rock that seemed interesting. I didn't measure the grains but I think rhyolite sized. 271 stack at 3.3x.

A nicely shaped rock that I found in the sand dunes.

My Gx8 now has it own special niche, it is my HDMI micro scope and Oly 60mm fossil camera. Here's the story:


So after a 30 year lull, my wife and I decided to do a fossil trip to "get out". She had never been. I had 12 hours of college geology and have done a lot of Devonian and Silurian digs (gave my collection to a friend who made a fireplace cover out of them in his home when I moved). I picked a location near the town of Timber, Oregon which has a nice Keasey Formation outcrop. But it is a dangerous climb so we settled for looking through the talus. My wife was very excited to find her first fossils:).

Here are a couple of images. First is a cast and either a mold or the actual shell, second is a comparison of the different sediments we found, and third is one with a mm ruler for scale. Back in the game for sure, even ordered some cleaning tools and a mason hammer (have a pick hammer) but needed something with a wide end and lighter for my wife to use.
Have two other images to ID, not sure what they are, perhaps a brittle star and then either a tooth or something else. Will post when I know what they are.

Feels good to say "I'm a digger" again:)

Nice finds, I’m looking forward to seeing more.
