High Ridge Wildlife Management Area Westminster

I located a wonderful large mound here, mainly by hunting systematically. I covered the area at the lower part of the map and saw a couple of possible rock piles next to the brook. But when I dove back in I found a large mound connected to short stretch of stone wall, in a pattern something like this:

It was hard to photo the whole structure. It was maybe a 40 feet long wall , with a 12 foot mound at one end (here the mound is one the left):

This is one of the biggest rock piles I have seen. When it gets big enough, let's call it a mound ("it's a beaut"):

Here is a view from the end of the stone wall:

 Hmmm. Big. Might have had more structure once.

I was curious if there would be a hollow on top. Indeed there was a small compartment:

Here is the video:

I suppose the wall led off in a particular direction which I should have noted. Here is one more view of where the pile connects with the wall:

There were a few traces of smaller piles in the area:

For the sake of the memory, let me mention that just before finding this mound, I interacted with a baby wren and had to reassure it I meant no harm.
