Most of my images of Atherton Brook, which is inside Quabbin’s Gate 15 in Shutesbury, are of cascades. Following to the end of the road gets us to the mouth of the brook and the reservoir with this little sand bar island that is most likely a leftover of sand and rocks from the days of construction.
Clicking twice, I believe, will yield a much larger view. This is one of my favorite Quabbin images. I may have posted this a few years back, not sure, but I reprocessed it and converted to black and white, so a little different if I did.
