In a previous entry, I posted about the Canterbury brook, and discussed searching out the above-ground section of the stream. Since a picture really is worth a thousand words, I figured I should post a nice satellite map to show what I found - and more.
**Note: the satellite pictures are cropped a little on this page. To see the full image as I describe it, please expand it to full size.
In the first image, Canterbury brook - a dark line here - starts on the right side at Morton st just under the route 203 marker and flows left through the old State Hospital property to American Legion Highway, under the road to the St Michael's Cemetery property. Follow the dark line over towards Canterbury st, and then back towards the Legion Highway to what is Walk Hill st. Under the road, it appears again - difficult to see in the picture - and goes underground at the car wash at the very lower left corner of the picture.
The second image continues upstream from the first. The brook goes under Morton st as before, and turns along Morton in the north side of the State Hospital site and seems to run right up to Harvard st opposite Hansborough st. I've yet to drive over and look at that property, but the picture does suggest a question: if the brook comes from Harvard st, where does that water ultimately come from? Is Canterbury brook just the outflow of a Mattapan storm drain? If you saw the stream bed as it flows through the State Hospital property, you'd think it came straight from a factory. Have you ever seen black algae? Yuck.
