Nick Martinelli@lizzard Pinacles National Park has the best small and large boulders. And little boulderers.

@JonDThompson or maybe not so huge if true, we can't know

Inmod@nancywisser @lizzard such beautiful boulders
peachfront"I am a large boulder in spirit, and you need to be looking beyond the limits of mere physical side, kthnx."
Here's my 20-pound "yard dog" specimen of Pitkin Limestone purchased in Arkansas from the family that found it. (There are no natural boulders to be had in my part of Southeast Louisiana.) You can see some Archimedes corkscrew among the fossils...
carter@lizzard from Zion National Park a few years ago, now those are some good boulders
Howard Chu @ Symas@lizzard it's rumored there's a coyote under there https://twitter.com/resisthaters/status/1617940083772116994
Rob@lizzard ahh , memories- i was living there at the time!
@leisuretime for some reason I got so into the spirit of it that I tried to find the exact spot on Google streetview

@kinyutaka amazingly small and large at the same time!!! Great Bouldering
Shield Maiden@lizzard Spotted on the walk back from Castle Rigg to Threlkeld, Lake District, UK. It almost seemed like it'd been placed there.
@Judeet88 Maybe by a large and small glacier!

@schardl8 this small boulderer the size of a large boulderer has small and large skills!!
CaptainSmartass@lizzard it's not the size of the boulder in the road, it's the size of the road in the boulder.
@captainsmartass that's what she said
Eff M@lizzard I think this was in West Bend, Wisconsin, USA several years ago. I'm not sure of the size, so it's definitely indeterminate sized!
@awfulhorrid what a beauty! I can't zoom in enough to guess what it is. Granitic maybe?
@lizzard Even looking at the full size picture, I'm not completely sure, but I do think you're right. West Bend if very firmly in the Kettle Moraine region of Wisconsin - "... composed of glacial sediment ..." so there are often huge chunks of rock (boulders, one might say!) displaced several hundred miles from their point of origin. That can make identification interesting when you don't have the sample in hand (or even when you do!)
Absolutely gorgeous area, too! I'm reasonably sure that was from a geocaching event.
@awfulhorrid I was thinking maybe the square looking bits are chunks of feldspar
cetan@lizzard @awfulhorrid it's Wisconsin. This is a block of cheese. 🧀 😆
@awfulhorrid @lizzard as a fib I'm very familiar with the many wonderful things Wisconsin has. 😎
I, Brash Saturn Ring TechTycho crater is known for its bright rays of ejecta and striking central peak. Turns out there's a boulder on the central peak. Just... sitting there.

The Unusual Boulder at Tycho's Peak | Science Mission Directorate
Why is there a large boulder near the center of Tycho's peak? Tycho crater on the Moon is one of the easiest features to see, visible even to the unaided eye (inset, lower right). But at the center of Tycho (inset, upper left) is a something unusual -- a 120-meter boulder. This boulder was imaged at very high resolution at sunrise, over the past decade, by the Moon-circling
@BrashTech omg I think that boulder is so famous and cool. It's in great company here on #BoulderDay
@BrashTech also much respect for your hashtag game
John Jenkins@lizzard Am I the only one who wanted this to have been in Boulder, Colorado?
@JohnEastLothian It should be a city wide celebration and the mayor of Boulder could go visit the og rock star to award it the key to the city
Gabrielle Cappelletti (G.K)@lizzard can I laugh?
@archangelic23 it is a holiday to celebrate the absurd and beautiful thinks the internet brings us, so yes!! Please laugh!!!!!

Ludibriumventis@lizzard Here are three boulders the size of boulders, hiding under the blankets (of moss).
Edit to add - my photo, taken in Whister, BC, Canada, June 2022
Andrew Feeney@ludibriumventis @lizzard Beautiful. I'm curious what size would you say that moss is?
@andrewfeeney @lizzard It was a bunch of different types! Shaggy mosses, pincushion mosses, mosses that looked like itty bitty pine trees...
It was so soft and I wanted to lie in it for hours, but alas, I only had a little bit of time for moss loafing.
@ludibriumventis @lizzard Look I don't know much about mosses, but I'd have to say to me it looks about the size of a medium sized er ... conglomeration of mosses.
@ludibriumventis they look like cozy friends snuggling up
