Could this be a grinding slab, or is it more likely just a natural feature?

That looks natural. It is incut too steeply. Features like this are common as potholes in granite.

Manos and metates

I have seen one ancient site where three corn grinding stations were still intact. They consisted of  flat square stones with adjacent vertical stones or walls in contact with the grinding stone - sort of like the trough type in the archaeological link.

How about a bedrock mortar?

(Don't do an image search for that term if you suffer from trypophobia :-)

Didn't see similar erosion patterns in other rocks in the area (on top of a ridge), hence my suspicion that it could be human-made...

One question in my mind: why would someone haul something to the top of a ridge to grind it when there are most likely rocks and stones closer to the food source?

It's a wide ridge with meadows and stands of trees, so it's conceivable that there is (or used to be) a food source there...

Super pretty!
Maybe there were (huckle)berries there at one time?

For the First Nations various places on the land were sacred. The holes could be human in origin and might not have anything to do with food. Unfortunately much of the oral history has been lost due to the upheaval caused through immigration by those of European heritage. The Mountaineers made an attempt to locate these sites but their efforts came up empty.

I could be way off base with this, but my guess that the reason they "came up empty" is that the tribes would not willingly disclose certain areas, especially "micro-sites" that are sacred to them, unless forced by something massive, like threatened development. I would not trust divulging info to any non-native entity and expect that the site would remain secret, and not eventually draw the curious.  Of course some sites are impossible to keep secret, like Devil's Tower.
