all known examples!!LOL!Well as said you obviously only know what you have read in a book,where are you?I tell ya what,we will meet up,and you pay me $1 for each one I show you all on private property that I guarantee no Arcy has ever seen,and you can see with your own eyes that they certainly are not all perfectly round!You obviously have no clue how they were made!If you were to go to that park in that link you conviently picked two round ones from,you would see for free that the long used ones are oval...on that point whirlpool pot holes are not oval!!!!That is against how they are formed!Oval grinding holes are from a long pestlethat is not lifted,its dragged around the perimeter of the hole...hell you can go to Yosemite Park and watch demo's on them doing that!!See I know all this for fact,didnt read it!Never paid a dime for it!!

Kuger no one is doubting your reputation. Most of the members hunt artifacts as seriously as you hunt a nugget or search for color. We can agree to disagree and the one thing about artifacts that is always true is if we all agreed we would not be learning and having serious discussions. That being said I will say this. We will keep it civil and respectful in our discussions. Everyone has a right to their opinions in an open forum. Agree?

I have to ask a question that I always wondered. When they used these type of mortars......how did they get the food out of the holes when they were done mashing them? I know they did use these types because I have seen them in the past and I am not doubting anyone. Thanks, rock

TN what you dont understand is I have collected Indian artifacts longer than anything.....including gold,as have four generations of my family.We have donated over 100 baskets and over 1000 arrowheads back to the tribe.....I dont guess,I dont post anything NativeAmerican nor will I,you will just have to trust me on that,maybe sometime if your ever out this way you can swing by and see a little of my "small",collection....I venture to say you might be a tad impressed and will for sure realise I am not some rooky rock picker.I posted this because it is unique and not often seen,I guarantee what I have stated it is,without a doubt.If you choose to disagree thats your perogative but just answer the questions I have posed I feel they may open your eyes.If I didnt know what these were I have no problem asking questions.

Rock,the meal was simply scooped by hand or other instrument,great question ...which brings up another fact....with these deep holes the top had to be elongated to allow one to get the "scoop",down to the bottom.These holes were passed down from generation to generation,I have seen where the bottoms were worn through

Wow a person who really cannot stand criticism. Well let me tell you a thing or two since you love telling everyone you know what it is. This a natural act caused by Glaciers. Quartzite is made of silica and sandstone. Making the breakdown process much easier. I have attached a National Geological survey to show that your area was littered by these stones. By the pictures you have submitted of the area around that boulder i am inclined to believe that is glacier left stone. I want you to read the paragraph where is says, FEATURES AT GLACIER POINT OFTEN MISTAKEN FOR EVIDENCES OF GLACIATION, then I want you to look at the pictures that follow that paragraph and the littered location of this glacier mass which would cover pretty much of all of California and then say is it possible this is one of those stones?? I do not doubt the fact that your family may have come across a true mortar but this stone is not one..........................GTP(Chris)

Gentlemen it can be discussed, even disagree without an attitude. Please keep it civil and not confrontational...

Wow I guess you know it all.......I am always willing to learn a new thing but with this it is common sense. I just added proof. Yet you read the whole thing and understand how Quartzite breaks down. I guess you knew that the rain found its way to the shallow part of the stone. Then started breaking down through a process of freezing and thawing and rain. The Quartzite is made of Sandstone and Silica. Heck you are a panhandler you should know that. What happens when you ad common vegetation to the mix. Like ferns, pine needles and other things that would add more acidity to the mix. I guess that breakdown just might happen a little faster in a area of the stone that is shallow. I mean it is only Sandstone and Silica. You have added no proof but harsh words towards anyone who contradicted your statement. Show me proof that shows me the same type of free standing stone with the same type of asymmetrical oblong circle holes, where it is peer reviewed that says it is Native American, then and only then will your words mean anything. Anyone can make up a background such as yours yet with everything you have stated not once have you shown me where this type of stone was used by Native Americans. The link you posted showed true Mortars and had noticeable wear around the well and at the well circle. These do not!
