I found this in an Indian camp in the middle of the desert. The artifact in the area date to before 1300 AD. I will let you guys post your opinions, and then I will let you the opinion of the local experts on the find. Yes, I do know the answer with 100% certainty, so I won't leave you hanging...

Re: Artifact or geofact? Opinions?

i wasn't clear enough, sorry...i meant that the cracks look very old, fossilized and worn down. if you look at round nodules as bubbles in the rock, you can see that some of the cracks run around the edges of the bubbles, which seem to be ancient cracks also. it would be nice to know if the lines are incised at all, but they look too natural to me and i would guess that they are worn down smooth.
his hand is obscuring a large part of the rock also, so it would be interesting to see more pics of the rest of the piece. maybe its a hammerstone with those cool markings on the back? or a nutting stone? hard to tell w/o looking at the other side.
it could be an awesome carved effigy on the other side for all we know :wink:
cool thing in any case

I,ll go with a geofact turned artifact!

Utah is known as a location for septarian nodules.
I think the material is a botryodal septarian nodule and the markings are natural.

Now, with that in mind, I will guess that a native individual found the geofact. The markings reminded him of a turtle shell. He worked on the stone until it resembled a turtle. He ended up with a septarian shelled turtle fetish that was the envy of the community.

That's what my vivid imagination has come up with. Now, move your fingers! LOL
 

Re: Artifact or geofact? Opinions?

Just another 2 cents worth, and I am probably just talking out loud to myself but the context of the comparison would seem to be "A natural minerial formation" and "a natural mineral formation that has been intentionally modified by human activity".

Or when does something in a natural form become an artifact? Per the dictionary ;when it has been intentionally modified by humans at a much earlier time then later recovered by an archaeological endeavor".

The term geofact is defined as "(from a combination of "geology" and "artifact") is a naturally-formed stone formation that is difficult to distinguish from a man-made artifact".

From the picture provided I interpret the shape of the rock as being natural, but as others have pointed out only one side is viewable. The consistency of the patina would seem to indicate the base of the rock is natural and not modified by humans. Based on this I would not categorize it as a geofact only a rock formation.

The top of the item is subjective particularly when you can not see the back side, If it were essentially the same on both sides then one may tend to think it was natural. If it is a solid patina on the back and the front patina has been etched or incised then you may conclude it was intentionally modified and could be categorized as an artifact.

If the markings on the front are superficial (not incised) but only a discoloration that could have been the result of natural chemical interactions (acidic solutions) or abrasion, then it would probably just be a rock with odd weathering patterns.

From a distance it can not be accurately determined.

You Must Tell US! PLease, I can't take it anymore...

Give me 15 minutes to take a few more pictures and I will have the answer. I will say you guys are good... :wink:

Natural rock. But one that even I would have to keep, cool looking-
 

Re: Artifact or geofact? Opinions?

Here you go, the pictures tell the full story. The markings are 100% natural and formed that way in the septarian nodule. My clue about it being found in the desert was a hint on what the material may have been. Looking at the back and comparing the patina and other factors to the front of the stone, it is clear that this rock has been polished in some fashion. The white quartz is harder than the the surrounding rock, so it is raised ever so slightly. On the back the quartz is sharper and sticks up more.

You guys are good, putting the clues together, and knowing there was a good reason I didn't show the back and hid part of the front with my fingers ::)

I am lucky to have gotten 2 artifacts from the camp only searching for a very short time. We were there to see the Uranium mines my Grandpa owned and hunt the petrified wood.

Thanks for playing, come again soon...Ryan

.......it is clear that this rock has been polished in some fashion.


I wouldn't think that was an indicator. 10 million years or longer in the desert is enough to polish ANYTHING if it is only sitting on one side. ;D

Take a microscope to it. If the grinding marks are in a circular motion then the natives did it. If it is in a straight or slightly curved line from one end to the other ... nature did it.

Natives sanded and ground things by mixing sand and water to make a paste on top of a flat rock. They would run it around in a circular motion and added sand and water as needed until they got the finish they wanted.

Looking at it under a scope will tell you if it's an artifact or natural. No way of knowing otherwise.
 

Interesting! Hi, other Utah person. I am north, where are you? :)

I am in Cedar Hills, right by the mouth of American Fork Canyon. How about yourself?
