Re: the "mortars":
I finally topped out at a peak with a house-sized boulder perched on top. I peeked around in the little caves at the base of it and noticed two deep grinding holes in the underside.
The first question is, were the holes ground in situ/with the boulder already in place, or did the boulder move into its current position after the holes were already ground.
From the brief description above, it is unlikely that the boulder moved, with the holes ending in a position fortuitously oriented with a small cave. (is at the peak, house sized, holes are completely smooth without prior weathering, etc; geologic process to "flip" such a boulder 180* in place. Sisyphean to roll it up, and so on)
More likely ground in its current position--which is not conducive to mortar utility for grinding acorns and such. ("Esmeralda, the acorn meal keeps falling in my hair and eyes! D'OH!")
(additional physical description can also help discern between mortar/metate/cupule)
Holes ground in non-horizontal rock surfaces have been associated with fertility rituals, and as portal representations, e.g. facilitating a portal for spirit travel.
Speculation with the paucity of evidence presented, and absent scientific rigor:
Atop a peak, 'neath a house-sized boulder, is this a spirit portal to the heavens?
In a cave...with *two* grinding holes... is this a couple of cupules as part of a fertility rite?
Might it reflect tree-carving geology-style, memorializing of a coupling in the cave, "Spencer loves Katherine?"

The romantic in each of us can decide for oneself.
(Pardon me for not doing homework for the board; a starting point would include work by Sr. State Archaeologist Breck Parkman)
Thanks very much for the TR, Robert, and please keep private any "special" locations.
kind regards,
