Blomfelt Conservation Land, Harvard MA

On my way back from an unsuccessful exploration in Pepperrell I figured to stop somewhere in Harvard - since those woods rarely disappoint. Went to the end of Glenview Rd and spotted (by coincidence) a conservation land entrance. This led into the woods and up a hill: I explored the eastern side of the hill, saw an interesting feature, where a stone wall ended at a boulder:
And, from there, I cut diagonally uphill. Surprise! Here was a rock pile near the top of the hill facing northeast.I poked around the area and found a cluster of maybe twenty rock piles, mostly very beaten down and smeared out.Some of these piles appeared to be rectangular. This is in contrast with the many sites I saw this summer and fall where the rock piles were triangular.Others?Looking at these pictures now, I am noticing they tend to be a bit lower towards the center: each one seems to consist of a slightly raised rectangular rim of rocks, surrounding a lower middle portion. Perhaps these are small piles with hollows? At the time, I was thinking these were a bit like the wedge-shaped piles of the day before (Tuttle Rd). I did notice a bit of three-in-a-row of evenly spaced piles ("markers").When I see marker pile characteristics, I look for a common vantage point. In this case there was a boulder at a few feet uphill that looked over the site:After taking photos, I continued along this part of the hill and found some other clusters. I was not sure if these were visible from the overlooking boulder. The furthest from the boulder, was the tallest pile I saw:This site was an interesting data point, in my surveying of piles with hollows, wedged-shapes, triangle-shapes, etc. It fit nicely with what came the day before and made me think I am starting to break away from the "tyranny" of always seeing triangular rock piles. Back at home, when I went to record the site as a "dot" on my topo maps, there was already a dot there. Good to be back and see more than before.
