Another Rock Pile with Rectangle Anchor Stone - Double Sunken Mound

This is another example of a type of rockpile that seems to use a 'rectangle like' rock as a type of anchor or signature. Along with a triangle shape on the other end. If this is a rock clearing pile, why would you take the time and effort to do something like this.

Could it be that maybe it was made by the same person? Almost like an artist signing his work or could it instead have some religious meaning? For more on this subject of Native American symbolism - http://stonestructures.org/html/symbolism.html.

Or could it be a type of burial or remembrance pile? Here is an example from a wall I talked about here.

There is so much to see on this site. Everytime I go I spot something different. Things like this double sunken mound or rock pile:

I've written about this site alot. From the walls that snake up and down the ravine to things like this:

Most of the records here in Johnstown state that the Native American's had abandoned the area by the 1700's. I don't believe that in the least. If anything, I believe that alot of would be remnants are long gone because of our history of floods. Indians weren't stupid, I believe they just headed up higher. I will be posting more on this subject soon. But until then if you would like to learn more about the history of Indians especially the Monogohela Culture in Cambria County - just check out my other blog at: http://cambriahistory.blogspot.com/2010/02/browns-farm-johnstown-lower-yoder.html.
