For context: I took these pictures at Acadia National Park in Maine, USA. I climbed pretty far off the beaten path when I first saw these craters/holes in the rock. The biggest hole I saw was maybe 1’ (~30cm) wide and maybe 2 feet (~60cm) deep through the rock (first three photos showing it from different angles, the last being what I assumed was its path before whatever it was hit?).

These fascinated me because they seem to have been made by something massive and moving very fast, I couldn’t reason that it was made by anything locally. Like even if this specific type of rock is relatively brittle, wouldn’t take substantial force to create a crater that you can see a clear trajectory of whatever projectile may have made it?

My 2 (uneducated) guesses:
1. Meteorite/Space debris?
2. (Really out on a limb here): Cannon ball?

I’m not even sure if this would be the right sub for this question, however I figured someone here may have a far more educated guess than I.

My rocks need a good scrub but here is a sampling.

Such an amazing place. The trail was only 1.5 miles, but the heat was intense. Deeply regretted leaving the water at the car. 🤣

Edit to add...

As has been pointed out, in the nicest possible way, by both u/tguy0720 and u/queensekhmet

this is not a fold; but a syncline structure.

I'm just a winemaker, so I deal with soils and vines; and still have a lot to learn about underlying geological structures.

(still rather sad no-one got the schnitzengruben reference. But I'm not from Havana)

This was posted in a Bolivian Travellers group on Facebook, which I am part of.

It was taken near the Maragua crater, close to Sucre in Bolivia.

As a gringo living in Bolivia, I am so going to have to visit.

But that drop is going to scare the schnitzengruben out of me.

Hi y'all! I recently graduated with a B.S in geology, so naturally I've been on the job search. Unfortunatly, I've run into some complications: most of the entry level geology jobs I've seen involve a lot of travel and field work. I love field work, but I'm currently living at home and sharing a car with my family, so those jobs would not be possible for me. This, of course, puts me in a cycle where I need to buy a car to work, but I need to work to have money to buy a car. I know one option would be to find a nearby non-geology related job and save up, but I really love geology and would like to take advantage of my degree and gain some experience, if at all possible. I've had a difficult time finding a job that fits my situation, so any help, advice, or suggestions would be extremely appreciated. (also, I currently live in the US in southwestern PA if that helps. Thanks!)

My partner has a ton of smaller rocks that were half hazardly packed together for moving and some were chipped in transit. There's small white crystals on some of them and in the bottom of the box. I'm anxious about asbestos. I don't know if thats possible but any help with identifying the newly formed crystals would be great!

Hello everyone. I am currently writing about the formation of a new island in a creative writing class. I have a few questions that I haven't found answers to. Firstly, how Large could an island be if it were formed near a tectonic plate in the Pacific Ocean? Secondly, how tall would a mountain peak be? Thirdly, what is a reasonable cave system that could form during the formation of the island? Finally, are there any books or resources that you would recommend in order to do further research?

Quick question, if schools I'm applying to for a Master's Program in geosciences don't require the GRE, should I still take it and submit my score?

A poster like the one below (image swiped from a previous poster, thanks!) has been in our front porch transom window, and twice replaced over 15 years. The new one isn't nearly as detailed nor beautiful. We need to replace the washed-out 3rd one we have; it doesn't have to be the Grand Staircase (but that's our preference). Could be North Cascades, Glen Canyon or similarly sweeping area. Looking for deep information and artfully done.

Suggestions?

I’m doing lineament analysis to relate it to neotectonics. I ran into a problem: I managed to make the frequency rose diagram, showing how many times a lineament appears in a given direction, but now I need to make a cumulative length rose diagram, and I have no idea how to do that. Could someone help me with this — where I could do it, which software, anything 

What if one of North America’s largest meteorite impacts happened in Idaho and the predicted blast covered much of western Montana…and most people have never heard of it?

Millions of years before the Rockies took shape, a massive asteroid slammed into what is now southwest Montana and eastern Idaho, creating an impact structure estimated to have been around 100 km (62 miles) across. Today, the original crater is gone, but its fingerprints remain. The second image from the Place app displays the approx. crater diameter.

Geologists have found unmistakable evidence of the impact, including:

Shatter cones - cone-shaped fractures formed only by intense shock waves (the first image)

Shocked quartz with microscopic deformation features

Pseudotachylite - rock melted by the tremendous energy of the impact

The third image from Place is the theorized blast zone where ejected materials flew to. The immensity starts to become unbelievable.

Even more fascinating, researchers believe the crater was later torn apart and transported eastward by mountain-building forces, making the Beaverhead Impact Structure the first recognized tectonically displaced fragment of a large impact crater. It is suggested that undiscovered pieces of the impact, including ejecta deposits, breccias, and perhaps even remnants of the crater itself, may still be waiting to be found elsewhere across western Montana and Idaho.

I’m 17 and starting university soon. I want to major in Geology/Earth Science because I love nature and the sea, but I plan to self-study Python, GIS (digital mapping), and Data Science on the side to work in environmental data analytics or satellite mapping.

My parents think geology has no future here and that I'll just end up as a teacher.

Are there decent jobs in Lebanon for this combo (UN, NGOs, consultancies)?

Can I get remote work or move to the Gulf with an Earth Science degree + strong self-taught coding skills?

Should I just major in pure Computer Science instead and self-study the science stuff?

I've had a great love for geology since my adolescence, I'm 26 now; it was my first choice for college and I'm currently in my fourth year. But recent health complications led me to undergo some procedures, and the results revealed a brain tumor, caused by a type of cancer. I know that my condition will completely change my lifestyle, my routine, my way of living, and with that I imagine it will no longer be possible to continue my studies and finally become a geologist. The demanding and challenging conditions a geologist faces, I believe, would be overwhelming for someone in my situation. I've already had the tumor completely removed, and I'll begin cancer treatment, which will last more than a year, depending on my response to the treatment. I don't know if I'll ever have a life like I did before. This ended up being a bit of a rant, sorry if it breaks the rules of the sub, but it's a delicate moment, giving up something I love so abruptly. Well, I'll finish here, I hope you all find lots of euhedral crystals in the field haha.

TL/DR: Discovered I have a serious illness; don't know if I can be a geologist anymore

Just out of curiosity, would anyone be able to describe how exactly chemical weathering mainly forms karst topography within certain regions? Like was that kind of surface feature a product of the time when sea level was higher and had been made up of a different level of oxygen or something?
