Likely granite, the broken bits makes me pretty sure it is, very common landscape boulders here often used as a hill landscape terrace retainer wall.

Looks like Granite to me.

Man, if BV doesn't know, we're in trouble. ;):D

The horizontal fracturing should be a clue, but sometimes we just take that for granite... ;)

I don't think it's granite, I'm from NH(The Granite State). My Grandfather owned a mountain there and I've never seen granite like that

Looks almost sedimentary, because of the layering but also melted at some point in it's history

I want to use it on a hillside in back and a big berm out front

Yes looks like some sort of shale/slate.. not a conglomerate, because it looks like it was formed from fine silty deposits..

You can see the wet periods... and the droughts..

Looks lime stoney to me. A close up of a fresh surface would help.

I vote for slate, a big hunk of slate

Molalla Boulders?

Hard to tell, but I bet its one of the three type of major rocks. I rule out Igneous due to the lack of (cant see it in the photo)small minerals that are usually associated with it. No veining or striations that are normal in Metamorphic ricks. My only bond head conclusion, some type of granite? It looks like they have been weathered pretty well. Judging by the chunks that are missing, its gray under there. I know, the nut case comes out:D in me when it comes to rocks. I was a geology major for a few years then quit due to lack of jobs.

Also, depending on the area, I bet most rocks come from local area. I can't see them shipping a bunch of rocks across the country say, from AZ to up state NY?

My money is on weathered limestone

Bill Douglas 12-26-2021 06:17 PM

I don't think it's schist (close though) but do a google images of schist because it may be the landscaping look you are after.

Blue stone

MBAtarga 12-26-2021 06:40 PM

As Bill mentioned above - that is not granite. The world's largest outcropping of granite is about 15 miles from where I'm sitting at home right now...

What part of the country is that photo from?

pavulon 12-26-2021 09:09 PM

Decomposed granite

ckissick 12-26-2021 09:54 PM

It looks like limestone to me. The rounding is from chemical weathering and the layering is from the original deposition. Of course, I would need a hand lens for a closer look and hydrochloric acid to see if it fizzes. I'm a geologist so...But I still may be wrong.

rusnak 12-27-2021 04:18 AM

it looks like sections of mortared together fieldstone from an old wall.

javadog 12-27-2021 04:27 AM

Weathered limestone.
