More west of Lovell Reservoir Fitchburg

A bit south of the first mound group I discussed here and through more than a little bit of raspberry, I came out into clearer spaces with more rock piles. Damaged.

And more particularly:

I was quite taken with the next one, and have panoramas from various angles:

It is a complicated structure - a genuine ruin.
Finally, some are more smeared out than others. It would be interesting to know why.

Quite a busy place, that otherwise inconspicuous bit of map.
