They were located up in Woodland on the corner of Minneapolis Avenue and East Mankato Street. The old pump house is still there as are the two concrete cisterns (or sewage tanks?) located just behind the pump house. They were replaced with a smaller, mushroom-style tower. Not sure when they were torn down, but they were still there in when I left town in 1973. There were many who were dared to climb the towers, but we were always fearful of the elderly lady who lived across Mankato Street who, we were told by the older kids, would call the police at the slightest sign of activity. There was also a large, five-foot nest of tangled barbed wire stuffed into the cage that surrounded the ladder. Here is a link to an old photo taken sometime between 1925 and 1935 from Woodland Avenue. The cemeteries are on the right and on the left is where Concordia Lutheran Church will be built several decades later. Minneapolis and St. Paul avenues are straight ahead. You can see the towers at the top of the hill directly above the car.
