Garnets
Did me and my friend finally find garnets? There were rocks like this littered all of over this one section of brook in VT. Should I return with a pan and a shovel to try and find some loose specimens?
Someone told me the little plume-like structures are “water escape structures”. Can anyone expand on this? (Jasper)

got a good look at what I think was the Monterey Shale Formation a few times :D Then what appeared to be sandstone

Could there be more types of volcanoes in outer space?
Kinda goofy title I know lol, but I was thinking that it's fascinating that Olympus Mons on Mars is a shield volcano just like we have on Earth. What are the chances that there are other types of volcanoes that we haven't discovered, and what could they look like based on changes in gravity and crust materials?
Where can I find borehole data?
Hi all,
Not sure if this is the right sub but here we go: I'm a software developer with a background in geology and have a strong interest in geological modelling. For my next job I really want to find work for one of the many big software providers such as Leapfrog, Surpac etc. To do this I'm trying to update my portfolio and have started working on a project building a 3D geological model in python. Can anyone recommend where I can find some open source borehole data? I'm looking for a good number of geographically concentrated boreholes to use to build a block model, all open source data I've found so far are sporadic boreholes. Or if you have any data you would be willing to share that would be much appreciated!
Many thanks
North Cascades Geology - what am I missing
For years I’ve been collecting geological publications and maps covering the North Cascades National Park in WA. Does anyone know of anything I might be missing?
First-ever map documents 33 glacial lakes hidden under the Canadian Arctic
Researchers have identified 37 active subglacial lakes across the Canadian Arctic, including 33 bodies of water that had not been documented before. The lakes sit beneath or partly beneath glaciers. Furthermore, some of them drain or refill so quickly that the ice above them can rise or fall by more than 100 meters in less than a year.
Polished Malachite from the Congo with Classic Banded Pattern
Polished malachite from the Congo showing classic banded structure.
Once it’s polished, the internal patterns really stand out — tight curves, layered growth, and strong contrast between the darker and lighter greens.
Malachite always has a way of looking almost fluid once the surface is finished.
Qualche estate fa... trovata nella riva del mare a Genova. È una pietra fredda al tatto,che cambia il colore in riflessi ad ogni movimento.. cos'è ?
Salve e buona Pasquetta ! Sapete dirmi che cosa è ? Trovata sulla spiaggia a Genova, qualche anno fa... portata dalla mareggiata alla riva. 🐚🐚⛱️⛱️🏖️
Starting Geology/Adventure YouTube channel
So, after thinking about life and what my future might look like I am considering taking my weekends to start a YouTube channel based around adventuring and talking about geology in different areas of the U.S.(as a start). I am wondering if this is a viable route to have fun in life and I was curious if anyone has experience with this? I don’t want to sound corny, but I yearn for some sort of adventure/exploration and it seems like the only way to do that nowadays is to get into content creation. Any advice would be great.
Lattice traps
For a book I am writing, I have chosen the following minerals to form lattice traps for rare elements. Are there any problems with these:
charoite
olivine
red garnet
blue sapphire
black zircon
calcite.
Any incite or suggestions are welcomed.
Earthquake Map
I create this dashboard for easy access to earthquake information.
