The Earth is in space, and it's made of rocks too.

I think this might be a helpful way to provide Earthly examples of the rock, and mineral diversity of our home planet Earth. We often see photos from other worlds, that seem at first glance, to be natural impossibilities. Other members then counter these far-out examples with pictures of Earthly analogs. Perhaps we could start a repository of Interesting, and unusual formations found right here at home. Submit your own pics. Or ones that you find across the internet. Please keep it to 1 to 3 images per post. And give some type of description that would make it easy to find using a simple search.
Maybe it's a lot to ask. But I think a Rocks and minerals repository might be helpful to all of us?
I'll start.

This pic was taken by me, just over my backyard fence. It consists of Mostly Volcanic Basalts, some Rhyolites of various colors, and a little bit of pumice. It reminds me of the Curiosity Landing area. Taken near Reno Nevada.
More to come, if others participate!




ETA: Those that post their OWN pics deserve and will receive a little more reward. Member Generated content ROCKS!

One of the "rocks" look very much like an alien skull.
It is definitely not a rock, and it is definitely not human, nor earthly.

This proves aliens have visited us. Or are still doing so.

Hi Space,

Here is my contribution :

Brimham Rocks are balancing rock formations on Brimham Moor in North Yorkshire, England. The rocks stand at a height of nearly 30 metres in an area owned by the National Trust which is part of the Nidderdale Area of Outstanding Natural Beauty.

Brimham Rocks feature in the Bee Gees' video 'You Win Again"'.

I spent many a happy weekend climbing on those rocks during my childhood days... *sighs*

funny. tell me which rock
If you contribute to this thread, I will go pick up the rock, and take a close up, just for you.

Wow, I would not even sneeze near that second example.
Thank you!

Whacked out on legal drugs and caffeine, I had to be the first to share the soft side of rocks.





You guys rock! Peace and Godspeed, Xenongod

Interesting but.....
Got anything real?

reply to post by spacedoubt


McMurdo Dry Valley, Antarctica: lots of ventifacts there, see here for more information.





If such 'rocks' were found by Curiosity on Mars, I'm sure the science team would have acquired lots of close-up images and at least pointed the ChemCam at these features to get some info about the rock's composition. Depending on the results, I'd then either publish the images & data or 'not' ...

This is in a cave situated in Hang Song Doon in Vietnam :

The pearls of Hang Song Doon





Phytokarst formation in the same cave

Can't be a coincidence that you posted this thread just days after I took this photo of a triangle rock.

Yes a triangle rock, no need to be obtuse about it, I'm acutely aware that...ok enough triangle puns, let's get right to it:

That 3rd picture even though we all know that it is a natural rock formation actually looks like a "Dinosaur" skull...

Imagine if that rock formation was on Mars??

Kindest respects

Nice pic, really cool. But no not the reason. There was another thread that happened to mention triangle rocks on mars ( a triangle on a triangle was the phrase), I kid you not!....I had just been out prospecting to Fossils in a Miocene lakebed on Sunday, and had seen some similar formations. And it prompted me to start the thread
I'm going to go back if its not 105 degrees this weekend...and BTW I found 1 Leaf fossil.

ah here we go

PS forgot to add., in this case, you are not "right" LOL

I must get some sleep...thank you all for your contributions so far in our Rock Show!

Go to Google images and search - ventifacts- that will keep them busy for a long time!
For example

Here's a rock formation that looks like Snoopy! This is in Sedona, AZ.

Love this thread.
Sorry no rocks from me at this point,
not even a pebble.

Here's a picture I took the other day of the gravel in the driveway....




I thought the one that I circled looked like it had a face carved on to it.

Of course each of these is about 2 inches long, and is "Crush and Run" from a gravel pit.

reply to post by eriktheawful

Thing is. Just from being crushed, all kind of interesting shapes can appear, based on where the rock decides to cleave under pressure.

I found this in a pile of fill dirt that had some shale chunks in it. Lo and behold, a 300 million year old "tree"..really more of a fern like plant.

reply to post by 1MrMarc


So that would probably denote a sandstone formation, that eroded away slower than the surrounding rock?
Which shows that these are deposited into water?
