Bore hole or what exactly is this from?

a reply to: ignorant_ape

Yup I agree, looks very much like a core drilled hole.

No idea why they would bother to do it there though.. Unless it's just for s#%ts and giggles.

never under estimate the alure of :

because i can .

although - on a " sensible " note - i would have drilled it to create an astronomical alignment on an equinox

It looks like a hole they drilled for a stick of dynamite. Ive seen those in Sutter creek while panning for gold. I also found a giant drill bit they used. It is about 20 inches long, pointed, with square sides. I think it is in the garage

Of course it's a core hole.... The picture looking up at the pile has bore holes at three o'clock all over the face where they blasted. No mystery here.

I don't think it was queried, on the other side of the rocks from where these pics were taken on the cliff face is the opening to a large cave. The opening looked to be 5-10 feet across.

This image clearly shows that the area has been subject to quarrying - note the striations on the rocks in the foreground.

Yes I saw that too.
OP great job on spotting that rock though, it does give one pause for thought, it must have had something to do with the other work done at that site.

Seems a curious place to drill a hole. There's no way it would be any use for draggies in that near end position, or blowing it up for that matter. Maybe they stick a flag in it if they are detonating

So construction workers do have a sense of humor. "Hey Marv does this new drill work horizontally?? Dang if I know try it!!"

Agreed. The vertical bore holes in the foreground are clearly present in the up close rock (before the hole rock.)

I'm not sure why someone would bore a hole that large on the upper background rock, but it seems they felt the need to do so.

Looks like someone wanted a sample of the rock. Used a borehole cutter to get it. Geologist, artist, etc.

Or perhaps it was done by a hitman/sniper to "pop" someone when they drove past.

To eliminate the possibility of this having an Equinox alignment you may need to go back during the winter or summer Equinox and see if the sun can be seen through it on sunrise or something.

A typical core drill isn't light weight so if this was just a prank then I imagine it wasn't easy to do. In quarries they jack hammer holes for dynamite.
Core drills are usually used for sampling the stone to test makeup and hardness.

A core cutter? That looks like a typical bore hole to me. JMO

Op- im a mining engineer and see this stuff everyday.

Kandinsky is correct, that hole is from the road being blasted out of the rock.
Left over holes are called bootlegs.
So what you are seeing is a bootleg hole.

Nice find!

Do you have compass reading...?

Would be intresting if the hole is ligned up with something...

Solar solstice or other

Hello everybody!

You asked for a geologist, here I am.
So I can confirm that the pictures show a standard size bore hole. The rock seems to be a basalt.

Nothing out of the ordinary folks

ALRIGHT ,who's playing with the damned alien weapons?
THAY can SEE that crap from ORBIT you know...

Could it have been made by Predators spaceship firing a laser beam just like in the film?

I live very close to an area with definitive quarrying, they got millions of dollars from the gravel. I take walks back there with friends or on dog walks and these holes are abundant out there.
Hey maybe aliens haven't figured out fuel yet so they use gravel?
Or, we're both seeing something left over from the drilling the quarry workers did.

a reply to: w810i

From building and cutting the road out would be my guess..

:-)

My guess is when they built the road they had to blast away material to clear the way. Could just be a hole from the drill used to put the explosives in.

I have no idea how deep they drill holes to do this, but if that rock was once the top layer it COULD of survived the blast I am guessing.

Cool pic tho!

I thought it might be from blasting, just seemed so out of place being so high up off the ground.
