What could have caused those holes in that stone? They are about the size of a little finger.
erosion.especially the change from cold to warm weather and vice versa.stone expands on warmth, then shrinks on cold = destruction.
one of those holes....it kinda looks like me. I think I should investigate this more.
>>94593NO DON'T!
Looks like the result of erosion, but specifically two different types of rock with different hardness. The hard one (granite?) erodes slower than the soft one (fuck knows what) and the soft rock leaves holes as it erodes.
The mixture would of course be due to interesting volcanic adventures millions of years ago.
So pet rocks count in /an/ now?
>>94672Rocks might be boring, but they're still nature... Especially when erosion is involved.
>>94672In after DDR-DDR-DDR!!!
>>94672nature too, fag
Might be Penitella Penita, or some other rock-boring mollusc.
>>94611Probably said it best. I suspect the holes contained softer organic material or materials that did not form into rock and were blown or flushed out over time. It could even have been air holes if it's a "fire rock". Do you know if it's light and soft? It may not be granite.
>>94672this isn't /pet/, moron. you're the cancer that is killing /an/.
