"Fat L" rock piles

Here is a standard design, one of the forms of rectangular piles with a "hollow":

Here is one beside Falulah Brook:

I wrote about that site here.

Here is one from High Ridge Wildlife Management Area. It is beside an un-named brook feeding the Whitman River:

 

I wrote about that site here, where this is located at the lower blue mark on the map.

I take it this is another. It is from near Brush Bush Hill Rd in Hudson NH. It is on a bluff overlooking Second Brook.

I haven't written about the site yet.

I am sorry they are hard to see in the pictures. They are not easy to photograph and not easy to see in the first place. I believe these are old burial mounds. It is no wonder people do not know about them.

So let's call these "fat L" piles, a variant of the "lazy 9" piles I wrote about here.
