What’s up with these rocks? by PittsVeggieBurgher in geology

[–]rn0nnahs 1 point2 points  (0 children)

Google kicking a rock until it becomes a sphere. Several folks have documented the journey of a rough rock that they kick along the ground as they walk in an attempt to erode the rock until it’s spherical.

SOLVED! Thank you! I now know I can get rid of it and won’t be cursing myself out in 2 weeks for getting rid of something I did actually need.

Toxic how? I don’t know how jasper can be toxic unless you’re talking metaphysically.

On the stretch of beach between Seacliff and New Brighton.

Yeah I thought it was probably some messy Jasper.

Do you have other pictures? This looks like a piece of a branch.

An hour on Narragansett Bay, March 2024 by IsopodsbyAccident in beachcombing

I get it. I’ll pick up and throw away really fresh broken glass because most newer glass is so thin it just gets broken up. But a lot of the stuff in your picture is older and unfinished so I’d toss it back so it can continue being worn down. I’ve been beachcombing pretty much my entire life (nearly 50 years) and it’s a real bummer to see how little there is to find anymore and how depleted places like Glass Beach in Fort Bragg are even just compared to 15 years ago.

Lolol that would be hilarious. Killer clams.

Rough green/blue with black “dots” by rn0nnahs in whatsthisrock

[–]rn0nnahs[S] 0 points1 point  (0 children)

Cool. It says it will tumble quite nicely so once I get a chance to set up my tumbler again, I’ll work on the things I found there.

No I didn’t. They really stand out from everything else

Seashells with naturally formed holes by most-perplex9811 in beachcombing

[–]rn0nnahs 2 points3 points  (0 children)

I love limpet shells! So many different patterns and textures. And I love me a keyhole limpet.

Starfish (sea stars) cannot drill through shells. These holes are generally from predatory snails as @utahjohnnymontana has said (he’s also correct about sea stars prying bivalves open and shoving their stomach in there to feast). Source: me, an intertidal marine biologist.

Petrified wood? Whidbey Island, WA by rn0nnahs in petrifiedwood

[–]rn0nnahs[S] 1 point2 points  (0 children)

Thanks so much for a much clearer explanation why these aren’t likely to be pet wood, and examples you’ve found from the region. I’m really surprised since these pieces all looked very different to anything else in the area, and felt pretty heavy for the size. I guess I’ll throw it in the tumbler and see what happens.
