A friend and I came across this and couldnt figure out what it is. It is maybe a mile or two away from Martha Furnace. Idk why the picture keeps coming up sideways....
I would like to add that there is a dim canal that appears to have feed the Cutts bogs from reservoir(s) behind the cellars at Calico. Maybe these pools were easier to use than the pump station.
(I may be using the name Calico in reference to the wrong area.)
