I don’t know the purpose of these holes

Drilled in the rock on the edge of the mesa, not far from a Pueblo.

Not sure about those but I know of similar ones used for blasting/dynamite.

I have came across these to and they are out in the middle of nowhere and have no idea what they are about, also they are in southeast Colorado.

How deep are they? How big around? Are they perpendicular to the ground or sideways into the rock.

Bed Rock mortars, blasting holes from mining, natural, lots of options.

They are about 1-2 inch in diameter, bored down into the surface rock that is on top of the bluff. I haven’t cleaned them out but they are not deep - maybe couple inches. They are definitely not modern.

No clue but thanks for sharing, I’d want to get to the bottom of those holes as well.

Are they (unusually deep) cupules?

Now that the weather is getting nice I need to head back out there and clean out the debris to get a better look at them.
