I have a project at a former surface mine/quarry and saw an area where recent rain eroded away sediment surrounding the gravel but not directly under it. Each rock was supported by its own column.
This is called pedastalling. It's also what happens when hoodoos form, just on a larger scale.
We watch for this as an erosion indicator in environmental assessments
Right on, thanks for naming it! I typically work with subsurface geology, so not quite as well versed in surficial stuff. I remember the basics from sed/strat and geomorphology classes in college. It's been a few years since haha
Here is the same thing writ large.
From the Enchanted City outside of Cuenca, Spain.
Sweet!
No problem. Us dirt (and rock) nerds need to stick together.
10/10 username btw
Rock ape strong together!
And thanks, it was a spur of the moment play on Grandmaster Flash haha
We have amazing hoodoos here in Utah. Went to goblin valley last year (where Galexy quest was filmed with the crazy rock fighting arena, it's real). The hoodoos there are phenomenal.
Woah they look like a bunch of little mushrooms at first 🍄
They do! Probably a little hard on the teeth though
probably not the best for cream of mushroom then haha xD Fr its really cool, and each has their own pillar?? how did that happen?
Water does really cool things. In this case, a relativity vertically falling rain will be deflected by the rocks, and the sand and other sediment around the rocks will be washed away. Here's a more zoomed out photo of the area
huh! thats wild how the erosion did that!
Absolutely! Water shapes a lot of what we see on a daily basis, ranging in scale from my photo to things like this. There are other geological forces at work, but water is one of the ones easiest to observe on a human time scale.
That's so awesome
