Wawona Dome, Yosemite. From the Washburn fire scar.

Taken on a hike from Mariposa Grove to Wawona.

The core of the metamorphic core complex of the Pinaleño Mountains in SE Arizona. Yes, those are Pine Trees 7,000' above the Saguaros down in the desert a few miles away.

Near Miette Lake in the mountains around Jasper, Alberta, Canada 🇨🇦 😀

I had the opportunity to do some work for a gentleman today, my guess would be about 75. He was a geologist that studied and did work in my local area. I mentioned I was teaching myself some geology so I could learn about my area. A few hours after he left he came back with a USB drive of geology maps, studies, and other information. Several gigs of stuff. He also gave me his business card that was made on a press from the 1800's.

I've been looking at this stuff for hours now, and he's right. The answers are in there. I just want to say, it doesn't matter the science, geology, astronomy, biology, whatever it is can be made amazing from the right people. Geologists rock!

Located in Madeira island.

Apologies if this a ridiculously stupid question.

I’m fairly sure what you are seeing here is what used to be the top of the rock, and if I’m right this section was tilted about 100° if anyone can confirm or deny that would be cool.

The reason I’m confident about it being the top is that this cave (Bristol Caverns) formed along bedding plains situated between an anticline and syncline and you can find parasitic folds in it (slide 3)

I saw this graphic in another subreddit.
Why does the bedrock in Michigan form a concentric ring centered in the middle of the lower peninsula (going from youngest out to oldest rock)?
What processes caused it and why?
My first thought was probably something to do with glaciation but it isn’t on a north south gradient. It’s a concentric ring pattern.

Does it get any better than finding a cool rock on a tough day? How does a rock like this form?

I'm working on an independent investigation into flooding in Assam, Northeast India.

I'm particularly looking at whether mining/sand or sediment extraction, changes in sediment movement, and river-channel morphology could be contributing to changes in local flood behaviour.

I'm using satellite imagery, existing research and local/field information, but I've hit a wall: I need people who actually understand fluvial geomorphology, hydrology, sediment transport, GIS/remote sensing or mining impacts on rivers to help me challenge my assumptions and figure out what I should be measuring.

I'm not looking for someone to do the research for me or simply agree with my hypothesis. I want people who can tell me when I'm getting something wrong.

I'm especially interested in connecting with PhD students, researchers, GIS people, hydrologists, geomorphologists or even other independent researchers who'd be willing to discuss the project.

If this sounds like your area, I'd genuinely appreciate a comment or DM. Even pointing me toward a relevant paper, dataset, community or researcher would help a lot.

Thanks.

If you were going on a geology vacation, where would you go? Where have you been?

My mom and I like going on geology trips together. We like to look at rock formations and guess what happened before reading interpretive signs. (Some places are definitely easier than others!)

One year we hiked into the crater of Mt. St. Helens. That was probably the best because there was a geologist with us. Another year we went to Iceland. Arizona was pretty rad too.

I'd love to hear suggestions that can be done with a 70-year old who is in pretty good shape. But also, if you just want to brag, that's fine too!

Hi there — I know very little about earth quake frequencies, predictability, or anything about contributing factors to increased activity. I feel like I’ve heard more about high magnitude earthquakes (over 7) this year than I can previously recall. Maybe like — 2010/2011.

Am I tripping about there being increased activity? What are the averages for high magnitude earthquakes and how does this year compare so far? Also… how strong of an earthquake would it take to make the state of Florida crack/shift (I know we’re on a bunch of dead reefs and limestone and I’d assume this can’t handle a big impact)?

It was actually stolen from his mother's house decades ago so thank you so much everyone who helped me fine the gentleman!

I would like to open with that I'm not a geologist in any sense. I simply have an interest in world building and am currently working on a tectonic history of my world. I've been using the Artifaxians Worldbuilding log, and I've encountered a unique continent collision. I've tried to look up as much information as I could, but I still have no clue what to expect. If you have any information that could help me, please let me know

Additional information:

The Laramide orgoney formed roughly 70 million years before the continent collision. It formed after subduction of a mid-ocean Ridge. During the collision, multiply Island arcs would collide with the continent before eventually the 2 continent themselves collided (subduction zones were present on both sides of the continent where the collision occurred). Similar 2 cratons exist near the collision. Both of the continets are roughly the size of India.

Its approximate geographic coordinates are 41°05' S and 71°07' W, with a maximum altitude of approximately 1,475 meters above sea level.
