If you get a call from people identifying themselves as “The Shop”, I suggest you run.
OK I have sort of a pyramidal rock in my front yard. 1/3 x 1,25’ x 1.7’ x 3’ x 160 #/cu’ = 360 pounds. Not near as big, but still way too much to pick up. I have been waiting for somebody to ask how I got it there. Well I stole it of a high spot on state land.

Can anyone tell me more? You can zoom in.
That is, indeed, a kick-ass rock.
Could it be a geode?
I will take it in a truck to a landscape store. First I’ll drive there to measure the truck. What’s the easiest practical way to measure water displacement? Don’t say put it in my bathtub… It’s my woods! I saw 3x3" of visible white without dirt on it. It was off the trail.
Love the Tommyknockers! It reminded me of that story while I was digging it…
@thelabdude- I feel it’s lighter than it should be in our calculations above.
Is the rock African or European?
Either way it’s likely going to require more swallows then the OP has on hand.
What about building a square, wooden frame around it?
Figure out what the volume of inside the open topped “cube” is, then top it off with sand, (or dirt?) from a known amount, greater than the volume of the cube. Now just subtract the volume of the cube with what’s left over from the volume of the sand. Voilá!
Nice pic, it’d be cool if it does turn out to be a geode.
I can’t think of an easy way. You would need a water tight container large enough to hold it and a way to get it in and out. Put it in, fill the container full or to a mark, remove it, and measure the water you have to add it reach the level with it in the container. It is too big for a 55 gallon barrel?
Is it just me, or does that rock look like a frozen turkey to anyone else?
Cool stone!
Is this thread the antithesis to going down to the quarry and throwing stuff in?
It’s hard to tell from the picture, but it looks like orthoquartzite (that “rock sugar” look is characteristic) with some recrystallisation on the bottom- you can’t cut it into “crystals”, that’s not how that works, quartz crystals are found that way, not cut. But those recrystallization patches could be tapped out. Doesn’t look geode-y to me.
It might be a different rock, try dripping some acid (HCl or strong vinegar or lemon juice) on it. If it fizzes even a little, it isn’t quartzite, but some limestone.
Truth is, all you need to do is tell your children that they must leave the rock alone. I guarantee it’ll be gone by the evening.
