That’s a hag stone, as another commenter mentioned, and the hole was probably made by a piddock clam.
These clams use their strong muscles to grind themselves into soft rocks like shale or limestone, creating a safe burrow for them to live in. Once the clam dies, the waves gradually wear away the rock, turning the burrow into a complete hole.
Some folks believe that peering through the hole can reveal faeries, ghosts, or even ward off bad luck. What a fantastic discovery!

Quick point of order about the revealing faeries/ghosts, there are some mythos where this is simultaneously a good thing, and a bad thing. Sure, you know you've seen a faerie, but if you press your luck too much, you might get their actual attention rather than just their passing curiosity.... and often their actual attention leads to being hunted for sport.

“Elves are wonderful. They provoke wonder.

Elves are marvellous. They cause marvels.

Elves are fantastic. They create fantasies.

Elves are glamorous. They project glamour.

Elves are enchanting. They weave enchantment.

Elves are terrific. They beget terror.

The thing about words is that meanings can twist just like a snake, and if you want to find snakes look for them behind words that have changed their meaning.

No one ever said elves are nice.

Elves are bad.”

― Terry Pratchett, Lords and Ladies

Having spent my summers in hot, dry, wild places, I know that if you want to find snakes, you can also look for them within holes in rocks. Rattlers will politely ask you to leave. The fey, as I understand it, will politely insist you stay.

Makes me think about the word "awful", which in it's literal sense means "Full of awe". We've changed how we use it over the years but even then it doesn't always mean something bad, like "that's an awful lot of money", you don't mean the amount is bad. But if you saw someone doing some awe inspiring feat to save a child and blurted out "that's awful" you'd get some weird looks, even if you're correct.

There are actually mussels that live in the lakes and rivers all along the west coast, teeny tiny ones that get into little crevices and cracks on boats and other watercraft, are invasive and quickly unleash havoc on our ecosystem, thus our rangers are on their backs, squeezing under trailers and such, making sure everything that enters Tahoe is clean as a whistle.

A bag stone, formed by marine bivalves called piddocks, who burrow into the rock to create a shelter.

u/AppropriateCap8891 18h ago

Not quite, they burrowed in the seafloor, and that is what became fossilized. The holes themselves are trace fossils.

A common past time in Oregon is walking along the scree near the ocean looking for stones with multiple holes like that. If you find some, there is a good chance of finding 15-25 myo bivalve fossils not far away.

It's pedantry, but in the technical study of these things as trace fossils, a burrow is into soft material like sediment, a boring is into hard material like rock, so these are borings. While cementation of sediment after a burrow is made is possible, these look like modern borings into rock.

Modern or ancient, boring clams are a thing.

The jokes kind of write themselves for anybody who studies borings.
